I agree with Snoseek that legalization is coming but I'm less optimistic about how long it will take. Once the old guard dies in great enough numbers it should happen. I think alot of older folks are just misinformed and the attitudes are so ingrained that there is absolutely no convincing people that it's much ado about nothing.
On TV these days you notice much greater pot use than in the past. Regular, everyday folks getting stoned because that's just what many people do. Non-violent, tax-paying, educated, pay their bills on time kind of folks.
I've often wondered how much of a hand the alcohol industry has in preventing legalization.
