[[caption-width-right:320:6.5% increase in total damage done, what do you mean it's not deadly?]]

->''"Tavius was right about one thing. I do have a fair knowledge of poisons."''
-->-- '''Otho''', ''Series/StargateAtlantis'', after [[HoistByHisOwnPetard getting nicked]] [[LastWords with his own knife]].

[[ExactlyWhatItSaysOnTheTin When a weapon is poisoned]] for added lethality. The weapon is frequently a dagger, but often an arrow, dart, or even a sword. Expect from such a weapon to ooze a [[TechnicolorToxin purple or green]] and possibly [[PoisonIsCorrosive stone-melting]] liquid. The poison is likely to either act instantly, or be [[AlmostDeadGuy timed to]] the FinalSpeech.

Poisoned weapons are typically [[PoisonIsEvil used by villains]] (and HungryJungle natives, who get a free pass), since they allow an easy victory or a spiteful revenge despite losing, especially in a duel. TheHero is usually too {{honor|BeforeReason}}able or [[LawfulStupid stupid]] to use it himself. Heroes down the SlidingScaleOfIdealismVersusCynicism and {{Combat Pragmatist}}s sometimes use poison. A literary device as old as time is to have a confrontation involving a poisoned weapon which the audience knows is poisoned, but the [[DramaticIrony characters involved do not]].

It should be noted that the poison being ''fatal'' isn't always the case. Often times, the poison will be nonlethal and merely intended to weaken, paralyze, or disorient the target instead. Reasons why vary from wanting to capture them alive, to avoid accidentally killing oneself, to wanting to actually kill them with their own hand but knowing they only stand a chance against them if they're weakened. It's almost never for safety's sake, where the villain doesn't want to risk killing themselves with an accidental nick of their own blade outside of combat. If the poison is actually lethal, it normally depends on who is hit with it whether or not the poison will actually kill them. If a hero is infected, the poison will normally be slow acting enough to permit a FindTheCure by his allies, but not always. If it's the villain, they're more likely to die. If an [[TheUndead undead]] is infected, they are immune to poison so it doesn't matter.

** One Bankai is revealed to be hiding the ability to leave a piece of the blade behind in an opponent's body whereupon it breaks down into a poison that destroys the enemy's cellular structure.

When Himari is grazed, Kuesu reveals the bullets have been coated with a potion that strips an ayakashi of their human mind and fills them with murderous bloodlust, the idea being that win or lose, Yuuto would reject Himari for turning into what he hates, a killer. Himari manages to resist the potion and escape.

If Akame faces robots or zombies, her sword is just a sword.

** ''Film/IndianaJonesAndTheKingdomOfTheCrystalSkull''
* The Na'vi of ''Film/{{Avatar}}'' dip their arrows - which they use primarily for hunting Pandora's megafauna - in a neurotoxin that will stop a human's heart in a minute.

* In ''Literature/TheLordOfTheRings'', the Witch-King stabs Frodo with a Morgul-blade. If Elrond hadn't cured him, the poison of the blade would have turned him into a wraith. It's also mentioned in the books that orcs sometimes put poison on their blades.
* In one of ''Literature/TheStainlessSteelRat'' stories, a character gets into a fight with an assassin, and the knife barely touches the assassin and he dies, it turns out not only did he have a ''very'' nasty knife but the knife was coated with a neurotoxin that would kill anyone on skin contact.
* ''Literature/ASongOfIceAndFire'': Oberyn Martell (aka The Red Viper) is infamous for using poisoned weapons, and it allows him to deliver an ultimately fatal wound to the [[TheBrute Brutish]] Gregor Clegane.

* ''Literature/SherlockHolmes'': The villain of ''The Adventure of the Dying Detective'' is a doctor who has killed his nephew by surreptitiously injecting him with a deadly illness. He later on tries to do Holmes in the same way by sending him a package with secret spring-loaded, virus-tipped needles, but Holmes is able to see through his scheme. (Having a lot of enemies tends to make the detective overly cautious of the mail he receives.) Holmes pretends to be infected, and he soon manages to lure the evil doctor over to his apartment and trick him into a confession in front of witnesses.
* When the anti-hero protagonist of ''Literature/AlteredCarbon'' goes to the armorer, among the weapons he buys is a poison-coated knife.
* ''[[Literature/TheBelgariad Mallorean]]'': [[MasterPoisoner Sadi]], one of the heroic party members carries a variety of poisons, and his major weapon in battle is a poisoned dagger. When [[TheMentor Belgarath]] asks the group to minimize casualties during a fight with {{Mooks}}, he's responsible for two of the three deaths at its close - "It's a little hard to unpoison a knife." (The third was [[CombatPragmatist Silk]] taking out an ambusher.)
* ''Literature/{{The Sword of Shannara|Trilogy}}'': Menion Leah, a heroic protagonist, poisons some arrows when the opportunity arises, just in case. He uses them in the very next scene to try and kill a dragon.
* A prequel to ''Literature/DeptfordMice'' series has enemies who wear golden claws with an impossibly nasty poison that causes you to pretty much dissolve into goo. When one character finds an unconscious one of them, HoistByHisOwnPetard is subverted by WhatAnIdiot when the guy decides to put on the claw and kill him with it, but accidentally scratches himself. He then runs away from the incurable poison already in his veins, and dies very quickly as opposed to using his remaining time to say, ''kill the one he poisoned himself getting ready to kill''.
* In some versions of ''{{Tristan and Isolde}}'', Tristan is poisoned by the Irish knight Morholt's spear (but wins the duel), and [[MosesInTheBulrushes sent on a craft without oars or sail]] as a last-ditch effort.

* Valeri Petrofsky of ''The Fourth Protocol'' by Creator/FrederickForsyth carried a handgun that fired hollow-point bullets ''[[AbnormalAmmo filled with cyanide]]''.
* ''Literature/TheCabinetOfCuriosities'' reveals that the [[DiscOneFinalBoss thought to be]] BigBad was [[spoiler: poisoning weapons, clothing, and other objects in an effort to find an effective means of destroying humanity, research he stopped only because he felt the creation of Hydrogen Bomb made him think the rest of humanity was perfectly capable of destroying itself on its own]].
* ''This Immortal'' by Creator/RogerZelazny: assassin Hasan (who has been forcibly disarmed) is forced to fight [[ImplacableMan the Dead Man]] and spends the time filing his nails. To really sharp points. His bullets (which weren't taken away) had meta-cyanide on them. He scratched the Dead Man at the start of the fight, and stalled until it dropped. Then he got the leader too.
* ''Literature/TheSaint'': The Saint himself discovered a poison-dart launcher built into a doorbell once. He avoided getting shot, kept the dart, and later used it in a booby-trapped parcel to [[HoistByHisOwnPetard prick the finger of the villain]].
* ''[[Literature/MrsMurphyMysteries The Tail of the Tip Off]]'': A rather ingenious example is found in Rita Mae Brown's novel. When H. H. Donaldson drops dead after going to a basketball game, an autopsy shows he was poisoned through an injection in the neck, but the poison would have had to have been administered during the game for it to kill him when it did. No one saw anything despite the bleachers being packed, and Donaldson didn't react in any way as he would have had someone jabbed him in the neck with a needle. [[spoiler: It turns out the killer froze the poison into an ice dart, and was able to kill Donaldson by shooting it our of a noise maker into his neck. No weapon was found because the ice melted, releasing the poison.]]
* In Creator/EdgarRiceBurroughs's original ''Literature/{{Tarzan}}'' books, Tarzan uses poison arrows that he steals from the natives, at least until he scares them into leaving a bundle out with some food every so often as 'tribute' to the forest spirit they think they've angered.
* In the ''Franchise/ConanTheBarbarian'' story ''Literature/BlackColossus'', Shevatas poisoned his blade to deal with the snake.
* In ''Literature/FromRussiaWithLove'', Rosa Klebb had a poisoned dagger at the toe of her shoe. She nicks James Bond with it and he passes out from the poison in seconds. The novel ends at that point. (Compare with [[Film/FromRussiaWithLove the film]].)
* In ''Literature/MemorySorrowAndThorn'', [[MagicalNativeAmerican Binabik]] carries a hollow walking stick, a small roll of poisoned needles, and a bundle of loose wool. When combined, these make a blowgun that shoots poison darts, allowing the diminutive [[OurTrollsAreDifferent troll]] to pack a lethal stealth attack.
* ''Literature/TheHungerGames'': How Maysilee Donner got so far during her games; she fought using poison darts. She was good enough with them to be able to kill a Career.
* In ''Literature/TheIronTeeth'', Saeter and his slave/apprentice Blacknail occasionally use weapons coated with paralytic [[GiantSpider timber spider]] venom.
* In Creator/MichaelMoorcock's ''Erekose/John Daker'' story ''The Eternal Champion'', Erekose uses the poisonous (or radioactive) sword Kanajana. The toxicity of the blade will kill humans and eldren with a slight scratch. Kanajana is so dangerously "radioactive" (Erekose himself isn't sure if it's radioactive or supernatural) that it needs to be kept in sheathe and can only be safely used by him.
* In ''Literature/HarryPotterAndTheDeathlyHallows'' it turns out that the sword of Godric Gryffindor is made from "goblin silver" that repels dirt and dust and "imbibes that which strengthens it", meaning that [[spoiler: since Harry stabbed a Basilisk in the head with it back in ''Chamber of Secrets'' it is now imbued with basilisk venom, one of the few things that can destroy a Horcrux]].
* In ''Literature/DarthBane: Dynasty of Evil'', the Huntress manages to capture Darth Bane by cutting him with knives coated in a fast-acting but non-lethal neurotoxin.
* According to ''Literature/StarWarsPhasma'', the eponymous character is a fan of these, [[spoiler:using a poisoned dagger to seemingly kill Cardinal, and also using a particularly nasty poison on Hux's father]].

[[folder: Live-Action Television]]
* In ''Series/XenaWarriorPrincess'', Gabrielle gets hit by a poisoned arrow. Xena has to look after her and find the antidote in time whilst fighting off an entire army.
* One episode of ''Series/GetSmart'' had some YellowPeril villain with long, poison coated fingernails. It probably best summarized that show, too, with him getting defeated because Agent 99 randomly had a bottled mosquito in her purse, which she used to get him to accidentally scratch himself upon swatting it.
* In ''Series/StargateAtlantis'' episode "[[Recap/StargateAtlantisS02E15TheTower The Tower]]", Sheppard ends up with the EvilChancellor trying to kill him in the climax. When Sheppard disarms him, Otho is cut with his own poisoned dagger and dies in moments, after providing the quote up above.
* ''Series/BuffyTheVampireSlayer'': Faith poisons Angel by shooting him with a poisoned arrow.
* [[OurWerewolvesAreDifferent Monroe]] uses an elephant gun with bullets coated in a special poison to take a [[OurOgresAreHungrier siegbarste]] in ''Series/{{Grimm}}''.
* PlayedForLaughs in ''Series/TheHeroYoshihikoAndTheDevilKingsCastle'' where a random {{Mook|s}} [[LickingTheBlade licks]] ''[[http://i.imgur.com/G3qokFu.jpg his very own poisoned knife]]''. TooDumbToLive indeed.
* It's mentioned in ''Series/BabylonFive'' that the [[TheReptilians Drazi]] often poison their blade tips.
** Centauri actually have jeweled hypodermic needles. In other words they treasure poisons the way humans treasure swords.
* In ''Series/{{Charmed}}'', darklighters are the only beings capable of killing whitelighters. They use arrows coated with a substance that is toxic only to whitelighters.
* In ''Series/{{Sliders}}'', Remy is shot by a Kromagg particle weapon. The wound isn't fatal, but the radiation poisoning that come with being shot would have been had he not been healed by a friendly Kromagg half-breed.
* ''Series/StarTrekDeepSpaceNine'' has a futuristic variant. Dominion weapons carry an anti-coagulant with every shot. Anyone they don't kill bleeds to death unless they can get off the battlefield and to a doctor.
* ''Series/TheDefenders2017'': Sometimes, the Hand's ninjas dip the blades of their weapons in a special poison that can kill their opponent.
** ''Series/Daredevil2015'': Said poison is used to wound Elektra when she and Matt are attacked investigating Midland Circle. Stick is forced to revive her at Matt's apartment using various ingredients from his kitchen. Elektra spends several days bedridden as she recuperates.
** ''Series/IronFist2017'': Said poison ends up getting into Colleen's body when she gets nicked in the shoulder by a ninja during a fight at one of Madame Gao's factories in China. It doesn't take effect until after she and Danny are back in New York City. Fortunately for Colleen, Bakuto is there to teach Danny how to use the Iron Fist to suck out the poison. That he knows the Iron Fist cures the Hand's poison is justified, since he is one of the Hand's Five Fingers.

[[folder:Mythology and Religion]]
* Hercules uses arrows dipped in the blood of the Lernean Hydra; wounds from these arrows are deadly as there is no cure. [[spoiler:He died when he wore clothes his wife had drenched in the blood of the centaur Nessus ([[{{Irony}} or in hydra blood in some versions]]), who had told her it would make Hercules faithful to her]].
* Paris used a poisoned arrow to kill Achilles when he shot him in the heel.

[[folder: Newspaper Comics ]]
* The Bandar Pygmy tribe, allies of ComicStrip/ThePhantom, are infamous for their envenomed arrows. A [[FantasticSlurs less polite term for them]], used by their neighbours, is The Poison People.

[[folder: Tabletop Games ]]
* The [[OurElvesArebetter Dark Elves]] in ''Warlords Battlecry'' will use poisoned weapons.
* Poisoned weapons are a game mechanic in ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}''. The latter has guns which fire ninja stars coated in a poison so horrible it ''makes the target's blood explode''. Generally used by the [[BlackAndGrayMorality even more evil races]], though in ''Warhammer'' they're a specialty of the close-as-you-get-to-good Lizardmen.
** Representing their love for this one, the Dark Eldar have poisoned weapons as an upgrade in ''TabletopGame/{{Warhammer 40000}}: VideoGame/DawnOfWar [[{{Sequelitis}} Soulstorm]]''. Note that according to the fluff it's usually nonlethal, as Dark Eldar want to take [[FateWorseThanDeath prisoners]]. [[GameplayAndStorySegregation In-game, it just makes their weapons deadlier]].
** This sometimes seems a little unnecessary, given the tech levels in TabletopGame/{{Warhammer 40000}}. For example, the Callidus Assassin is armed with a gun that rips your brain apart, a sword that can cut through anything in the universe except the Great Old Ones who invented it... and a poisoned knife. Which in some circumstances is [[RockBeatsLaser exactly what you need]].
* ''TabletopGame/{{GURPS}}: Ultra-Tech'' has a shuriken made of "coherent sound" that can be used to deliver poison when it attacks.
* ''TabletopGame/{{Exalted}}'': [[GreenThumb Wood Aspected]] Dragon-Blooded are capable of producing a magical plant toxin from their [[BattleAura anima]]. They can poison you with a simple touch or unarmed attack, or with a very basic Charm can also channel this toxin through a weapon.
* Essentially, virtually every action adventure-based tabletop [=RPG=] (which is to say, most of them) will have at least a few paragraphs on the effects of poison on player characters -- from a simple "save or die" to lovingly detailed descriptions of a given poison's exact effects over time. Some systems (notably early editions of [[TabletopGame/DungeonsAndDragons (A)D&D]]) then promptly go out of their way to make the use of poison ''by'' player characters in turn as impractical as possible or even ban it outright, while others won't bat an eye.
** In D&D Fourth Edition, poison use is one of the main shticks of the Executioner Assassin player class. The class makes a certain number of uses of poison each day (determined by level) which can be applied to weapons or used directly on enemies. Other classes have access to poison-based powers as well, but since the poison damage type is resisted by more creatures than any other damage type, it's not the best type of damage to specialize in.
** 3rd Edition has a 5% chance of accidentally poisoning yourself when applying acid to a blade, although certain classes, such as Assassins, are trained to avoid this. It's still not very practical, however, as the good stuff is expensive, and by the time you can afford it in mass quantities, most enemies will make their Saving Throw easily.
* In ''TabletopGame/HcSvntDracones'' pretty much everything out of Spyglass's weapons division is poisonous. The Fang is a dagger with pores in the blade and a reservoir in the hilt, Shardshot a glove-dart launcher, while the Shrapnel Gun only has the "Poisonous" effect because it's close to having your body filled with shards of jagged metal. Though the description for "Poisonous" ammo notes that bullets would need to be too hard to shatter to be useful and the explosion and velocity would strip most coatings so only a few weapons can use Poisonous ammo, like Spyglass products, and compound bows.

[[folder: Theater]]
* Poisoned weapons featured in a number of Shakespeare's plays, perhaps most prominently in ''Theatre/{{Hamlet}}''.

[[folder: Videogames ]]
* In a flashback of ''VideoGame/SuikodenII'', it is revealed that a previous border-skirmish between the Highlands and the Jowston Alliance was to be settled with a [[CombatByChampion contest of champions]] - a duel between the greatest hero of both sides. That those two happened to be personal friends was supposed to make it into an honorable fight. However, when the battle was joined, the hero of Jowston, Genkaku, refused to even lift his sword. Eventually, Highland's hero had no choice but to simply disarm him and claim victory. Genkaku was condemned as a traitor and banished to Highland... but later, it was revealed that the Major of Jowston had surreptitiously poisoned Genkaku's weapon in order to ensure a victory - but Genkaku had realized this. If he had let this subterfuge be known, it would have triggered renewed hostilities between Jowston and Highland, so instead, he simply refused to swing his poisoned blade...
* In ''VideoGame/SuikodenV'' [[spoiler:Lyon]] is stabbed and near-killed with a poisoned dagger.
* Some weapons in the ''Franchise/FinalFantasy'' series inflict the "Poisoned" [[StandardStatusEffects status effect]] on enemies when they hit.
** In ''VideoGame/FinalFantasyV'', Sword Mages/Mystics can enchant their swords with the poisonous Bio spell, adding magical poison to their attacks.
** In ''VideoGame/FinalFantasyVII'', any weapon with two linked materia slots could be associated with an element or status effect, including poison.
** In ''VideoGame/FinalFantasyIX'', the Rune Tooth and the Poison Knuckles can both inflict poison, while the Scissor Fangs can inflict the more dangerous venom.
** In ''VideoGame/FinalFantasyX'', you can give any weapon this ability.
** ''VideoGame/FinalFantasyXI'' has poisoned weapons as well, but they're generally [[AwesomeButImpractical not that useful.]]
** In ''VideoGame/FinalFantasyMysticQuest'', {{ninja}} Tristam's shuriken are imbued with poison and paralysis abilities. The various claw weapons you find on your journey also inflict poison and paralysis, with the stronger ones adding even more status effects.
* [[KarmaMeter Possible]] hero example: [[Franchise/MassEffect Commander Shepard]] can equip his/her weapons with Polonium rounds (if you can handle enemies breaking down into [[NightmareFuel green vapor]] after death).
* The Assassin class in ''[[VideoGame/BaldursGateII Baldur's Gate II: Shadows of Amn]]'' can poison their weapons. There are also poisoned arrows. The poison is also applied to any traps the assassin deploys while under the 'poisoned weapon' effect.
* ''Franchise/{{Castlevania}}''
** The Hrunting in ''[[VideoGame/CastlevaniaChroniclesOfSorrow Aria of Sorrow]]'' is an example of a poisoned sword.
** If you have the right combination in ''[[VideoGame/CastlevaniaCircleOfTheMoon Circle of the Moon]]'' (Manticore and Mercury), you can make your whip poisonous. Another combination (Manticore and Mars) turns it into poisonous claws.
* ''VideoGame/DungeonsAndDragonsOnline'' features weapons with the poison trait, doing extra 'poison' damage and some kind of ability damage. Rogues also have an enhancement available that adds additional 'poison' damage to their attacks. The MasterPoisoner Ninja Spies are the most dangerous with their own brand of poison that increases in toxicity while worsening damage from stock poison weapons. Enemies are worse; one poisonous sting or bite from some medusas or demon will outright kill you if not immediately treated.
* ''VideoGame/WorldOfWarcraft'' has a number of notable examples:
** Rogues can apply various poisons to their weapons, granting extra damage or certain special effects when an attack lands.
** Hunters have special shots called "Stings" which are loaded with various toxins that can cause InstantSedation, DamageOverTime, ManaDrain or loss of accuracy. These work like the Rogue's poisons, but unlike them, only one Sting can be in effect on a target. In ''Warlords of Draenor'', Stings were largely removed except for the sedative version, although a new optional ability called Exotic Munitions was added, which plays with this trope.
** During a duel between Garrosh and Cairne for leadership of the Horde, Magatha Grimtotem poisoned Garrosh's weapon (taking advantage of his ignorance of the pre-fight blessing tradition) so that a single lucky blow defeated the almost victorious Cairne. Garrosh was less than pleased.
** Some of the buffs you can get from the Mantid Paragons while questing in the Dread Wastes poison your weapons. For example, Xaril the Poisoned Mind coats your weapons with a poison that after eight hits on a target, severely damages the target and stuns nearby enemies.
** In Mists of Pandaria, [[spoiler:Vol'jin]] gets stabbed with a weapon that interferes with his regeneration capabilities. It's up to you to find the herbs necessary to heal him.
* Players in ''VideoGame/RuneScape'' can create poisons to use on daggers, arrows, spears and a few throwing weapons using the Herblore skill. There are three poisons, each stronger than the previous, and they're made from a herb and a dragon scale, a cactus spine and spider eggs, and poison ivy berries and belladonna respectively, from weakest to strongest. Belladonna is potent enough to strongly damage the player just when it's touched with bare hands.\\
Additionally, a small octopus caught on a tropical island, and when somewhat heated it becomes as poisonous as the strongest poison - then it can be ground into a paste that can be applied to spears only, though. The reason of such a limitation? [[ObviousRulePatch There is no real one.]] Only the mentioned select few above weapons can be poisoned, too - many other bladed weapons can't be.
* Poisoned weapons are featured frequently in ''VideoGame/FireEmblem''. There's usually no way for you to get one though, making them UnusableEnemyEquipment (or rather, Unobtainable Enemy Equipment). In games that allow you to steal or otherwise obtain an enemy unit's equipment, the poisoned weapons are converted into [[GoodWeaponEvilWeapon plain old iron weapons]] when in your possession.
* In ''[[VideoGame/FireEmblemTellius Radiant Dawn]]'', you can disarm an opponent and steal them and they'll still be poisonous. Not really worth it, since they do less damage than iron weapons, but it is still possible should one want to use them. A unique weapon of this type is the Valaura, a poisonous {{Light|EmUp}} [[HolyHandGrenade Magic]] tome. Explained that it's corrupted magic.
* Arrows in ''VideoGame/NetHack'' can be poisoned, which can lead to much frustration since poison can sometimes cause instant death.
* ''VideoGame/{{Magicka}}'' has several poisoned weapons. They also are the only way to create poison elementals.
* ''VideoGame/DiabloII'' allows low-level Necromancers to enchant daggers with poison. Poison enchantments on weapons was also quite common, even though these enchantments were generally far from lethal in any way.
* There's Bruno from ''Quest for Glory I'' and [[spoiler: the same Bruno's]] in ''VideoGame/QuestForGloryV''. The poisoned daggers were a plot point in the second. The hero could obtain and even use one. Not recommended if you're playing a [[LawfulGood paladin]].
* ''VideoGame/DeusEx'' features poisoned crossbow bolts, which serve as tranquilizer darts (though they kill ''you''). In [[VideoGame/DeusExInvisibleWar the sequel]] there is a similar dart gun, but also a hidden, poisoned dagger. Striking your enemies with it makes them cough from the poison in addition to extra damage. This is especially useful as continuous strikes will have your opponent hacking so much he won't have the chance to fight back.
* ''Franchise/TheElderScrolls''
** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' allows you to [[ItemCrafting Enchant]] the Poison spell effect onto your weapons. Unlike most instances of this trope (where one dips or coats the weapon in poison), including those from later games in the series, this makes the Poison effect permanent (as long as the weapon has Charge).
** ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'', in a more traditional use of the trope, lets you apply poisons to your weapons which will deliver the poison's effects on the next enemy it strikes. Poisons can be found or purchased, and you can also create them yourself through the [[AlchemyIsMagic Alchemy]] PotionBrewingMechanic. This causes [[FridgeLogic some confusion]] as to how a [[DropTheHammer warhammer]] - [[CarryABigStick or other blunt weapon,]] which [[MindScrew has no method of actually transmitting the poison into the host's body]] - can be poisoned in the same manner as, say, [[HeroesPreferSwords a sword]] or [[AnAxeToGrind an axe]]. (It can also be applied to a ''bow'', although its implied that you're actually applying to the next arrow fired.) Further, "poisons" can have effects beyond simply dealing damage. Poisons can drain [[{{Mana}} Magicka]] and Stamina, or inflict "weakness to" [[ElementalPowers certain elements]], or inflict other StandardStatusEffects such as Silence or Paralysis.
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', poisons are used similarly to ''Oblivion''. In addition, one can apply them directly to [=NPCs=] by, for example, reverse pickpocketing the poison vial into their inventory without them noticing.
** Poison also appears in the {{MMORPG}} [[GaidenGame spin-off]] prequel, ''Videogame/TheElderScrollsOnline'', [[RuleOfThree where yet again]], it delivers another case of FridgeLogic. Poison is made with the Alchemy skill line, which creates vials to be equipped neatly next to your weapon of choice, which in turn are consumed 20% of the time you attack with your weapon to apply their effects. This happens even if you are equipped with a magical staff that shoots fire and lasers. Some learnable skills also include poison in their attack; the Bow line, for instance, has three skills morphable into poison versions.
* ''VideoGame/BattleForWesnoth'' has a Poison weapon special, used (in mainline) on Orcish Assassins' throwing knives, and Ghouls' claws. This ability turns both, especially Orcish assassins, into DemonicSpiders.
* The Dart Gun from ''VideoGame/{{Fallout 3}}'' utilizes Radscorpion venom, and will instantly cripple the victim's legs as well as causing damage over time; the effect stacks up with the number of darts hitting the enemy. Interestingly enough, a sting from an actual Rad-Scorpion does not cause the crippling effect, only the initial damage and HP drain.
** The Ant-Agonizer's Ant Sting knife also has a poison effect.
** ''Point Lookout'' has the Fertilizer Shovel.
** ''VideoGame/FalloutNewVegas'' ups the ante, by allowing you to craft numerous types of poison and apply them to any melee weapon. It wears off after one use, making it less useful on standard weapons, but kickass on thrown ones.
* ''VideoGame/MystIVRevelation'': According to Achenar's journal, he used poisoned spears to kill the two large sea monsters (known as Cerpatees) in Haven.
* In ''VideoGame/AssassinsCreedII'', Ezio can get a poison upgrade for his hidden blade. It's the quietest weapon in the game, and because it has a delayed effect, you can poison a target and then get long gone before the target finally dies. An [[GoodBadBugs interesting bug]] in the game means that if the poisoned target, while flailing around uncontrollably, hits anyone, all the guards will blame you and go into high alert.
* ''VideoGame/MonsterHunter'' series: Poisoned weapons do exist, but they behave a little differently from the norm. First, each monster has its own tolerance to poison -- Bnahabra die instantly from poison smoke, while bigger monsters tend to resist it more readily. Also, each monster takes a given amount of damage maximum from the poison, and no weapon can inflict more or less. That said, a weapon's Poison attribute is in fact its virulence - a higher attribute means that the poison starts doing damage with fewer blows. Neurotoxins (paralysis) and sleeping agents (sleep) behave in the same way.
* ''VideoGame/{{Exile}}'' and ''VideoGame/{{Avernum}}'' give players the ability to poison melee weapons or arrows. Handy for taking out that nasty spellcaster hanging out in the back, as multiple hits from poisoned weapons makes the poison worse. There's also the Alien Blade, which constantly drips poison.
** There are enough enemies dealing poisoned attacks to make poison resistances and cures necessary. Same with the ''VideoGame/{{Geneforge}}'' series.
* Early FPS/RPG ''VideoGame/{{Strife}}'' allows you to use poisoned bolts for your crossbow, turning it from your weakest weapon to a OneHitKill weapon on grunts.
* ''VideoGame/CommandAndConquerGenerals'' allows the [[{{Qurac}} GLA]] to infect their tank shells with toxins given the proper upgrade. [[MadScientist Dr. Thrax]], in the ''Zero Hour'' expansion, takes it UpToEleven and places poison on ''everything'' in his arsenal.
* The Latin Junta in ''VideoGame/MarchOfWar'' have a similar combat philosophy to Dr. Thrax.
* ''VideoGame/DarkSouls'' has some poisoned weapons, throwing knives, and arrows. Also, enemies in Blighttown use poison darts and giant clubs. Rotten Pine Resin can also be applied to almost any weapon to temporarily add a poison effect.
* In ''VideoGame/LeagueOfLegends'' [[BadassAdorable Teemo]] uses a blowgun with poisoned darts, [[RodentsOfUnusualSize Twitch]] uses poisoned crossbow bolts, and [[{{Pirate}} Gangplank]] soaks his blades in grog - which is apparently pretty strong stuff, because it deals damage over time and slows enemies it hits. [[SnakePeople Cassiopeia]] and [[MadScientist Singed]] cut out the middleman and simply blast people with contact poison or gas.
* The Viper Blade and Scorpio Staff can inflict poison on targets in ''VideoGame/KidIcarusUprising''. And any weapon can be made poisonous with powers and customized abilities.
* One of the robots in ''VideoGame/TheJourneymanProject'' shoots the player with a tranquilizer dart that will kill them if they try to leave the laboratory without finding an antidote first. The same dart gun is used to neutralize the BigBad at the end.
* Certain ''VideoGame/BattleRealms'' units have weapons that have poisoned. The Serpent Clan's Zen Master Shinja dual wields poisoned swords, while the Crossbowman and Bandit can have their crossbow bolts tipped with poison. Lotus Clan Diseased Ones exude a poisonous gas to attack.
* In ''VideoGame/SyphonFilterTheOmegaStrain'', Lian Xing gets to use poisoned shurikens while on a ninja-style stealth mission disguised as a Sherpa.
* The [[GameBreaker Game Breaking]] Nightglow Sword in ''VideoGame/JadeCocoon'' delivers a guaranteed poison status to nearly any enemy and all but one of the ''bosses''.
* ''VideoGame/DwarfFortress'' has various syndromes that can be carried by monsters. [[http://www.bay12forums.com/smf/index.php?topic=139121.0 !!Science!!]] has shown that these syndromes can be applied to weapons for lots of [[UnusualEuphemism fun]] for both [[VideogameCrueltyPotential your enemies]] and [[HoistByHisOwnPetard your dwarves]].
* ''VideoGame/WarcraftIII'' has two main kinds of poison: Envenomed Weapons does damage over time (but can only reduce HPToOne if the target runs away) and Slow Poison slows the target's movements. The Undead's Disease Cloud also deals low damage for a long time without killing, the Night Elves' Orb of Venom gives the hero Envenomed Weapons (and an anti-air attack if melee) and the Warden's Shadow Strike hurls a poisoned dagger for massive damage, damage over time, ''and'' slow.
* ''VideoGame/DragonsCrown''
** The Toxic Extract skill of the Elf allows her to add poison to her arrows and daggers. [[AllThereInTheManual The Dragon's Crown artbook]] mentions that elves specifically use poison harvested from Hydeland's cat-sized scorpions for their weapons.
** The [[SpreadShot Cranequin]] crossbow the characters could pick up use poisoned bolts as ammo.
* From ''{{VideoGame/Bayonetta 2}}'' there's the [[Creator/FranzKafka Kafka]], a large bow crafted from a demonic dragonfly that can shoot out venomous spears or even infernal insects, all of which can poison an enemy and slow their movement. Also, when she uses the Tetsuzankou technique when wielding the [[MorphWeapon Rodin]] the weapon will turn into a poisonous whip that can hit multiple enemies at once.
* One of the targets in ''VideoGame/HitmanCodename47'' and it's "remake" ''VideoGame/HitmanContracts'' (The same target) wields a poisoned sword that he will use in combat if he spots 47. This acts as a one hit kill in the first game, and deals a lot of damage in the remake. In the remake, 47 can take the sword, and use it against guards, although it's not a very good idea, as the sword cannot be hidden or taken into other levels. In addition, the target's personal bodyguard is immune to the sword, either for unexplained reasons or [[Kevlard]].
* In ''VideoGame/{{Evolve}}'', Val and Abe's adaptations both carry guns that inflict poison damage. in addition, both hunters and monsters have access to perks that add a poison DOT to their attacks.
* ''VideoGame/FortuneSummoners'': In the StoryWithinAStory, ''Magical Girl Merrin'', Part 4/12:
--> goblins descended on Merrin from all directions. Their swords were bent and rusty, their bows and arrows small and ridiculous... but even these could be deadly when coated in terrible poison, and the weapons lashing out at Merrin were.
* ''VideoGame/{{Chantelise}}'': As the FlavorText for the Poison Crystal says:
--> Coats your sword in poison.
* In ''VideoGame/{{Gigantic}}'' Voden can poison his arrows with toxic spores, while Ramsay can coat his Whipblade with the poisonous juices of a Juju fruit. In both cases the enemy struck with a poisoned weapon is inflicted with the Poison status effect which deals damage over time and makes healing less effective.
* In ''VideoGame/MordheimCityOfTheDamned'', this is the other specialty of the Skaven warband besides being the FragileSpeedster choice. Their unique racial skills allow any of their troops to poison their weapons, and their heroes can also equip Weeping Blades (sinister curved blades dripping with a sickly glowing poison) and Warplock Pistols (matchlock pistols which fire ''poison-coated bullets''). Yes, they ''do'' stack. A Night Runner with Warplock Pistols and mastered poisons and pinning or crippling shot is a ''nasty'' combo that can leave even a mighty [[GiantMook Impressive]] to die slowly, powerless to move or fight back, round after round.
* Anyone in ''VideoGame/NexusClash'' can use weapons coated with lesser poisons regardless of their position on the KarmaMeter, including a variant in armors that poison anyone who hits the wearer. The truly nasty poisons are the exclusive domain of [[NamesToRunAwayFromReallyFast Defiler]] demons, who don't ''need'' weapons.

[[folder: WebAnimation]]
* The [[https://vimeo.com/236345931 pilot animatic]] for ''WebAnimation/KnightsOfAllRealms'' focuses on the "Sick Sabre", a weapon owned by the legendary bandit Burdis the Butcher. He never took the time to properly clean the blade after every fight and would rub it with mud and garbage. Covered with centuries worth of filth and bacteria, it is so potent that the slightest touch of the blade will leave a man violently and perhaps fatally ill.

[[folder: WebComics]]
* In ''Webcomic/RiceBoy'', T-O-E (one of the good guys) carries a poison blade, possibly anticipating that he would have to fight Golgo, and that poison was the only thing that could kill Golgo.
* ''Webcomic/TheOrderOfTheStick'' has Daimyo Kubota using a poisoned ring to kill [[spoiler: Therkla after she decides to act in a way that is not in his best interests]].
* ''Webcomic/GirlGenius'' not only [[http://www.girlgeniusonline.com/comic.php?date=20110907 hints]] that [[McNinja Smoke Knight]]'s weapons are poisoned, but shows how it can be used for an insult (what with those poisonous frogs and all):
--> '''Tarvek''': Violetta -- have you been licking your ''knives'' again?
** Violetta also uses a variation. Zola high on "[[SuperSerum Movit]] #[[UpToEleven 11]]" receives a blowdart in the back and mocks the attempt... until Violetta explains the nature of the poison.
---> '''Violetta''': Tsk, I know that. That wasn't poison, that was more Movit #11. Now all I have to do is [[ExplosiveOverclocking watch you combust.]]
*** More people with Smoke Knight training have shown up, and every time anyone has been hurt by them, a poison was involved. It's like they don't have any ''non''-poisoned blade.
** [[http://www.girlgeniusonline.com/comic.php?date=20120523 Wulfenbach commandos]] had poisoned dirks. Fast-acting stuff, apparently.
* In ''Webcomic/{{Strays}}'', [[http://www.straysonline.com/2011/10/page-191/ Feral's foe uses them.]]
* In ''Webcomic/{{Digger}}'', Boneclaw Mother augmented her NaturalWeapon by coating the claws of her left paw in poison, in case things got desperate. Afterwards, she had to clip them down to the quick to remove the poison.

[[folder: Web Original ]]
* ''Roleplay/SurvivalOfTheFittest'': Blood Boy's assigned weapons are an Ida (an African sword) and a vial of poison meant to be applied to the blade.
* Phase (Ayla Goodkind) of the ''Literature/WhateleyUniverse'' is now carrying some poisoned throwing darts. When chided for it by an instructor, she shows she also carries a syringe of antidote.
** By way of contrast, the instructors never bothered to even ask MasterPoisoner Jobe about this; it's simply assumed by everyone that any of the dozens of holdouts she is carrying is coating in something potentially lethal, and the fact that she's known to carry antidotes for them only goes so far given the sort of nastiness she uses.

[[folder: Western Animation ]]
* In one episode of ''WesternAnimation/TheSimpsons'' with Homer's brother, Herb, Bart is given a membership card to the NRA as a present from Herb so Bart can buy a machinegun when he's older. He asks if he can get armour piercing cyanide-tipped bullets to go with it. Herb replies, "It's in the constitution, son."
* In ''WesternAnimation/{{Sandokan}}'', one evil tribe uses poisoned spears.

[[folder: Real Life ]]
* Generally speaking, poisoned weapons were not very commonly used in warfare, as they were an unreliable and overly complicated way of killing a person. Any injury inflicted with a poisoned weapon is more than likely to bleed out faster than the poison could be absorbed; even if were to be absorbed in sufficient amounts, it would take some time before the effects actually come into play. Typically, poisoned weapons were mainly used for hunting, in which case the poison can be given enough time to take hold and debilitate an animal, so that a hunter can catch up and deliver the final blow. For obvious reasons, this requires a poison that is relatively benign and/or destroyed by the heat of cooking.
** In exception to the above, poisoning darts and arrows was a fairly common practice in ancient times; in fact, the word ''toxic'' comes from the Greek ''toxikon'', a poison made from yew extract for use on arrows (''toxa''). However, this was mainly done to make up for their lack of power and wounding potential: as projectile weapons became more powerful and more deadly, the practice became less and less necessary for warfare. The only place where poisoned projectile weapons remain in widespread use today is the Amazon, where local tribes use poisoned blowdarts hunt small animals; popular toxins of choice include [[https://en.wikipedia.org/wiki/Curare curare]], as well as the secretions of certain frogs called...well...[[https://en.wikipedia.org/wiki/Poison_dart_frog poison dart frogs]].
** Though poison itself is a common method of discreetly killing people, poisoned weapons have been rarely employed for assassinations. However, there are noticeable exceptions: Bulgarian dissident Georgi Markov was assassinated in 1978 by a ricin-filled pellet, which may have been shot into his leg by a KGB agent using a modified umbrella.
* Prior to the 20th century, most casualties in warfare were not caused by enemy action, but rather by secondary causes. Wounds could easily get infected, leading to illness and eventually, death; insanitary conditions in cramped conditions allowed for illness to spread easily. Some people realized that the risk of infection through injury could be increased [[DungFu by smearing their weapons with feces]], which was employed by the Viet Cong during UsefulNotes/TheVietnamWar in combination with traps using [[SpikesOfDoom sharpened bamboo poles]], commonly known as Punji sticks. Likewise, [[GrievousHarmWithABody corpses were often used as projectiles]] during medieval sieges, in hopes of spreading disease.
* In 1973, an African-American school superintendent by the name of Marcus Foster was shot multiple times by the Symbionese Liberation Army. During the coroner's examination, it was discovered that all eight bullets contained cyanide. Somewhat unsurprisingly however, [[RealityEnsues the cause of death was from being shot eight times]].
* British scientists during UsefulNotes/WorldWarII worked upon a grenade shooting dozens of poisoned needles instead of your common shrapnel. The project was scrapped; the [[CoolButInefficient sadism-to-usefulness]] ratio was too wide.
* Early bullets were usually made entirely out of lead, which is a toxic metal. Assuming that a gunshot victim lived long enough, secondary poisoning from the bullet lodged in their body may become an issue. It is for this that "lead poisoning" became a common euphemism for getting shot. Modern bullets are generally made out of lead as well, but coated with copper (which tends to be less toxic).
* Depleted uranium, a byproduct of enriching uranium for weapons or nuclear reactors, is used by a number of countries for military purposes. The density of uranium (which is much higher than steel or lead), along with its propensity for spontaneous ignition and self-sharpening on impact, are all ideal qualities for armour-piercing ammunition. Depleted uranium is chemically toxic and mildly radioactive; while the residue from a single round is unlikely to do lasting harm, firing thousands of them across the battlefield can leave enough toxic dust to cause long-term health problems in those exposed to it.
* A development called Dense Inert Metal Explosive (DIME) uses powderized tungsten alloys to limit the size of an explosion while maintaining lethality. While intended to reduce collateral damage, there are concerns that the metal particles ejected by the explosion could potentially be highly carcinogenic.
* Poison bullets exist but aren't very popular. They would be illegal to use in war are intended for varmint control. They reach major MasterOfNone territory since there really isn't a reason to use them over poison traps or just normal bullets.
