Ironclaw has some.
We've created "new" drugs, because we want the roleplay of drugs, crime etc. without making it too close to home for the other players. The primary drug in use is called an "exotic grain" which looks like a grain of rice that is swallowed.

That helps us avoid the problems of players OOC having strong opinions. In another game where pot was introduced, you'd get problems where some players would strongly oppose the drug, while others would strongly endorse it - which is fine from a game perspective, but bad when the players OOC feelings are too strong on the matter. Keeping it that little bit distant helps the players react as their characters rather than as themselves.

Our drugs are primarily just emits to the player to let them know how they're feeling, as well as emits to the rest of the witnesses. The emits might not always match (so one drug may make the character feel confident and suave, while the audience may see them drooling and slurring their words.)

We also have a lot of drugs used for medicinal purposes (which some characters are addicted to)

And, of course, tobacco and alcohol...

Amusingly, since our characters are anthro animals, most of the cat players roleplay that they treat catnip as a drug, too.
