Liked the concept and as others have said the hand-drawn menu is really cool. The game fits the theme as well.
Some general ideas, that popped to my head:
maybe it would be interesting to have the drugs be part of the game some more? Like you have the lines under the table to snort, but if you decide not to, you get signs of withdrawal: paranoia, can't focus, some irritating noise etc. If you take another line, momentarily you are hyper focused, but the more you take the more you get messed up so you try to balance it, but there really isn't good balancing with these things, so yeah.. :D
Fun game overall!
