Look at what Marc Emery is doing in Canada with his political group in BC. From what I noticed when I was there over Canada Day and the 4th-o-July, it doesn't seem like marajuana is an issue and they were openly smoking and selling pot all over the place.
It seems like they are on their way legalizing it there, might be a good "field test". Canadian and American culture is really close in many ways....... so ya never know.
