I smoked all through high school.. a year or so out of high school too. Couldn't find a good job because all I could do was sit around and smoke pot. Working at walmart. I quit the shit, got a nice job.. then I turned 20, and started drinking. A lot. I've pretty much gave that up too.. down to just weekend drinking.
I don't look down on anyone who smokes pot though, you do what you want.. but don't come complaining to me when you need money.
