In response to a few emails let me say, I don’t for a moment think pot is harmless. I don’t really care what studies you cite, I know way too many people who permanently frazzled their brains smoking too much pot, particularly when they were teenagers, to say its harmless. But I also know plenty of fully-functioning decent people who display almost no negative consequences. Whether it’s a chemical thing or a psychological one, pot does make lots of people slow and burny (that’s right: burny). But people don’t rob liquor stores for weed and it’s reached a point in the culture where I think it could be profitably regulated through non-criminal means. Anyway, we can have a fuller argument about that another day.
