In fiction, having to use an inhaler at all immediately alerts the audience that this person is a nerd. It is rare or almost impossible to see anybody considered to be cool using one.

This is usually not TruthInTelevision, because whether or not you need to use an inhaler has little to no bearing on your personality. However, if you have asthma or some other kind of breathing problem, it might prevent you from participating in strenuous sports, fitting with the nerdy stereotype. This probably accounts for the association.

Before inhalers, some people with weak health/lung problems (notably Creator/RobertLouisStevenson and Creator/HGWells) turned bookworm to entertain themselves when confined to bed and ended up with literary careers. Improved technology (visual media and inhalers) now gives us this trope as visual shorthand.

A SicklyNeuroticGeek is also likely to use an inhaler. Compare GeekPhysiques.

* A Virgin America ad invokes this: A woman is on a plane sitting next to a handsome, chisel-jawed dreamboat until she drops her phone and he turns on the light to pick it up. When he comes back into the light, she's shocked to see he's a nappy-haired, scrawny geek with an inhaler. She turns the light back out, and he immediately goes back to the hunk.

[[folder:Film - Live Action]]
* Mikey in ''Film/TheGoonies'' has one that he throws away at the end of the movie, insinuating that now he's had adventures he's less nerdy. This is probably justified due to the fact that he was misusing it before, and has realized it's time to stop focusing on his weaknesses if his life is going to move forward. Treating an inhaler like a security blanket leads to over-medication, and ultimately, worse asthma.
* Averted by Wheezy Joe in ''Film/IntolerableCruelty'', [[HandicappedBadass a killer for hire with asthma]] whose VaderBreath is heard whenever he's onscreen. [[spoiler: He dies when he accidentally puts his gun instead of his inhaler in his mouth during the confused fight between him and the attorneys and pulls the trigger.]]
* Subverted in ''Film/BlackHawkDown'' as nobody would try to claim any of the soldiers were the nerdy type.

* Played with in ''Literature/TheRepublicOfTrees''. Louis has asthma. Although he certainly doesn't look like a nerd, he is the idealist responsible for the group's "revolution" and, at least initially, the brain of the operation [[spoiler: it is also a symbol of his poor grip on reality - he wants to create a perfect society but he has no way of getting new inhaler in the forest. As the result, his health gradually deteriorates, finally causing him to go badly sick and be declared "unfit to rule" at the worst possible moment ]]
