I believe in legalizing marijuana. I feel like as far as drugs go, it's pretty harmless. If anything, it's less harmless than alcohol. More violence occurs (domestic violence, rapes, etc) under the influence of alcohol than marijuana.
That being said, I don't exactly think pot turns people into "go getters". In fact, quite the opposite. If you want to sit around your house and smoke pot all day, that's your business. But don't expect me to have any respect for your lack of ambition.
