I haven't been ON anything for almost a year. But my drug of choice would be weed. It tastes good, it's fun, and taken in moderation, it's almost harmless. Alcohol is fun, but that can be pretty hazardous. And trying Absinthe is a secret dream of mine.
Actually me and my friend tried morninglory seeds (same effect as acid, except they're legal) but they taste like crap and you have to take a LOT to feel anything. That's about it for my drug stories.
