I'm watching this one closely. I think there's been a tectonic shift in the public attitude towards marijuana, beginning in the 90's (the backlash to the whole 'just say no! One joint will fvck you up for life! And pot smokers are commies!!' 1980's) and I don't really see anything stopping the progressive relaxation of marijuana laws.
I know a lot of you younger people on here don't realize how many functional people you know smoke weed, because they hide that from you. When you get my age, your eyes will open: and unbelievable amount of people who you'd never think would ever touch the stuff smoke up on a regular basis. I personally know teachers, law enforcement officers, doctors, physicists, and even clergymen (well, man) who fire up at least occasionally. Of course most hide it from the eyes of the young, because it is still illegal and the young have loud mouths.
It's no big deal, and I'm glad people are finally realizing that. I look forward to the day I can walk down to the local smoke shop and pick up some dro as easily as picking up a 6-pack.
