You guys make it sound like everyone will smoke pot. I think if it becomes legalized it will just be like alcohol but with slightly less damaging effects to your body and environment. Obviously some people will abuse it but most won't. And I'm pretty sure anyplace that is so accepting of weed like California or places in Canada already have such easy access weed that the legal matters isn't stopping many.
Legalizing it is more like removing relatively innocent people from prison's and reduced funding for crime with less people make money off grow ops.
Pardon my possible ignorance on any of these views as I neither smoke weed or drink alcohol.
