I think EVERYONE was anti-drugs at one point. Its like graph said, kids aren't bright and will believe anything. And since we were all told "drugs are bad" at some point, we believed it for awhile. So in a sense, EVERYONE was like this at SOME point, even if you first smoked weed in the 3rd grade, i'm sure you were against drugs in kindergarden through 1st or 2nd grade atleast.

Depends what you consider a "pothead". Would going to school everyday make you a 'schoolhead'? I think not. Because what the hell is a 'schoolhead'.
