I never cared what they were doing - didn't hang out with that crowd. A buddy of mine and I did shave the "T" off of Tylenol, dunked them in food coloring and made a few bucks selling them to a druggy classmate that swore he was really getting "F'd up" on them. We'd only sell two at a time to him so he couldn't down a pile of them and have that come back on us!  ;)

A better question to ask would have been "What were the rest of my friends parents doing when their kids were engaging in those practices?". I had some fear of my parents.
