Not so much in the category of illegal or questionable substances, but somewhat related: two things I've made mention of in RP are willow bark and Shroud lace.
Willow bark is just that. It has had RL uses as a substance for reducing pain and inflamation and is, in fact, a precursor to aspirin. The bark contains salicin. Not that the technicalities would be well known in Eorzea except to, maybe, alchemists.Â
That said, alchemists might be able to distill the salicin from the bark and turn it into drops or another form. Otherwise, the bark can be chewed, but it's slower to act in this form.
As for Shroud lace, IRL known as Queen Anne's lace, it has been used as a form of birth control by chewing the seeds of the plant, or grinding the seeds and mixing them into a tincture or tea. I wanted to come up with a name for it which fit the game's setting, and Shroud lace came to mind. Chewing the seeds tends to be less pleasant because they're bitter and gritty, mixing it with a liquid makes it more bearable.
