Idea's for various drug effects?

I’m working on a drug manufacture system, and i have got to the part where i’m making the drugs it can make.
How ever i can’t think of any other drug effects besides setting player health&armor, so i was hoping some of you could give me some ideas?

Death by explosion
Death by ignition
Death by drunken brawl

How about some visual stuff? Like crazy colours or maybe limited Vision, very high mouse sensitivity for a short amount of time. You could also change their movement speed and all that good stuff.
