I've done some bumps and went on a binge with some crystal a while back. It was pretty fun, until I was coming down and thought it would be fun to drop acid. 3 days with no sleep + tripping... wee. :-\
I don't really like amphetimines anymore... I don't even touch cocaine. I just feel gross and disappointed in myself whenever I give into the craving.
But, anyway... I think demonizing a person for their choice in intoxication is rather silly. To the outside world, all you are is a worthless stoner.... yet, you accuse someone else of being a worthless meth-addicted loser. wtf.
