1. Yes, I was like this growing up. I sucked down everything the DARE cops told me and swore I'd never do drugs. As I got older and more confident in thinking for myself, I made educated decisions as to what I would and would not do.

2. IMO, a 'pothead' is someone whose life revolves around smoking. Someone whose day is not complete unless they 'wake and bake' or they have to smoke every hour, on the hour. Not to say there is anything wrong with that, to each their own. But like with alcohol, would you call someone that has two beers a day after work an alcoholic?
