Cannabis Sanity

Joe Klein wants to end this Prohibition era:

...why not do it? There are serious moral arguments, both secular and religious. There are those who believe with some good reason that the accretion of legalized vices is debilitating, that we are a less virtuous society since gambling spilled out from Las Vegas to "riverboats" and state lotteries across the country. There is a medical argument, though not a very convincing one: alcohol is more dangerous in a variety of ways, including the tendency of some drunks to get violent. One could argue that the abuse of McDonald's has a greater potential health-care cost than the abuse of marijuana. (Although it's true that with legalization, those two might not be unrelated.) Obviously, marijuana can be abused. But the costs of criminalization have proved to be enormous, perhaps unsustainable. Would legalization be any worse?
