I think it should be kept from being used for bad purposes, cannabis does have good purposes but if its in the wrong hands it can be deadly(I had a friend die from tainted marijuana) its criminal past is what destroys it rep.
How many people can you think of who have died from alcohol abuse or drunk driving? Probably more than just that one person who supposedly died from some tainted pot, I'm guessing? How many people do you know that have died from lung cancer because of smoking, dipping or chewing tobacco? :dunno:
I know a guy who's now blind because he drank some bad moonshine when we were in high school. Yeah, that was "illegal" liquor, but until a few years ago, you could still legally buy Ever Clear here. And everyday (especially this time of year), there are stories about people who leave parties after only having "a couple of beers" and kill a family in their mini-van.
So let's be honest, prior to 1937 or '38 (someone correct me if I have the date wrong), marijuana didn't have a "criminal past"... because it wasn't illegal to possess or grow hemp! This whole thing came about (ONLY) because paper and oil interests wanted to eliminate the competition.
Reefer Madness was a propaganda movie. And that's all it was. But it was successfully used by the Federal government and American lemmings to send us down the road to Stupidville.
