More drugs.

[Sundance]

There's also bath salts and cat drugs. And cocaine exists as an admin-spawned item. The bag you stuff your face in, then go apeshit.

Though I would like even more botany drug plants.

I did mention cat drugs silly.
But I totally forgot about bath salts, that evil evil drug.

Yeah, being able to produce some more drugs in botany/outside chemistry would be pretty neat. That's why I mentioned being able to grow poppy's for morphine. You could ghetto mess with it to make heroin.
Or ghetto make amphetamines and cocaine like suggested.
Glitter could be cool as it could be synthesized through bees somehow.
