Y'know, I have nothing against people smoking pot if that's their thing, but I don't want to be randomly confronted with clouds of pot smoke as I make my way through downtown as a pedestrian. I'm very sensitive to that shit, and I don't appreciate the secondary 'high'.
Pot should not be treated like cigarettes in terms of open public use. It's bad enough on my nose and lungs since smoking was forced to become a 100% outdoor phenomenon by our enlightened lawmakers, but pot is a drug. I don't wish to be involuntarily drugged because someone else needs to exercise their rights at the expense of mine.
If it's going to be legalized, do it the Dutch way and make it illegal in public, but legal in your home and in 'coffee shops'. That way, everyone's freedom is served as much as possible.
