I would rather trust a man whos laid back and smokes some pot from time to time than a man who snorted coke and had a drinking problem (George W Bush.)
I may have my own misgivings about drug use to...enhance one's life, whether they feel it adequate without them or not, but if the choice came down between trusting a pothead and trusting coke fiend, I'll take the stoner any day of the week. The worst they do is listen to shitty music, buy fractal artwork, and eat.
