I've heard it's less dangerous than alcohol, so I don't see why not. We already waste a lot of police resources of this reletively harmless drug. But then, I'm no expert.
It is. I'd have to dig up the Lancet article, but marijuana is less addictive and less harmful than either tobacco or alcohol, both of which are legal. Marijuana contains tetrahydrocannabinol (THC) which, as we know, has various health benefits, up to and including staving off cancer.
Legalizing Marijuana and levying a tax on it could save us a huge amount of money... not only by making a major cut to spending on the Drug War (I think possession of marijuana is actually classified as a greater crime than possession of
cocaine, but I could be wrong on this one.), but also by raising revenue from sales of marijuana.
Legalizing and taxing marijuana is a good thing. End of story. I also believe that if you oppose its legalization, you should also be in favor of illegalizing tobacco and alcohol, but this is personal opinion.
