When you're on Jet, it's like your brain and body are in overdrive. Time seems to slow down, or you feel like you move faster, or something, like you can do so much more than you usually can. Super dangerous, super addictive. Buffout does...pretty much what it says on the jar. Steroids, makes you buff, can also make your heart stop. And Psycho, fuck, Psycho makes you feel powerful, invincible, like nothing in the wasteland can touch you, like you aren't just some pathetic and weak person in a fucked up world. It also makes you feel like murdering everything in sight. And it makes you agitated and makes your gums bleeds, so, you know, that's attractive.
