Or, if they are a smoker, you can poison their tobacco. This has the advantages of being a substance they will willingly take into their body without any urging from you, and may smoke it some time after you poison it; meaning there is no immediate link between you and their death.
This is most commonly done with cigarettes, but can also involve cigars, pipes, chewing tobacco, snuff or even E-cigarettes and vapes.

The cigarettes had been laced with opium, and the Turkish soldiers were too stoned to fight. Given that Meinertzhagen is pretty much the only source of this story and the dubious accuracy of said diaries, it's entirely possible this story was entirely made up (though it's certainly an amusing story nonetheless).
