So in FF XIV, we have at least two kinds of illegal narcotics in Eorzea: Somnus and milkroot. If there are any others, I don't recall them, but please apply the following questions to them as well, for me, with citations too.

I'd like to know more about these drugs: Who produces them? How are they made? Where are they made? Who usually consumes them and where? What effects do they have on the user? How are they used (smoking, inhaling)? What form do they take (e.g: liquid, plant, or solid)?

Any information would be appreciated.
