Smoking pot hypocrisy
While California (and liberal places) hate smokers with a blind, seething, "we know better than you" passion... they make an exception for slackers and pot-smokers. Those are OK, so get a special exemption from harassment. Which shows the hypocrisy of their position. They don't care about smoking, they want to tell you what to do. Cigarettes they don't like, so bad. Pot they do like, so OK. Any one with moral convictions against smoking would ban both. (Eat the weed). Those who support the exemption are hypocrites. (Or bay area Democrats, which is the same thing).
