Decriminalization Or Legalization?

Marijuana

Matt Steinglass was for marijuana legalization before living in countries with lax drug laws. He now prefers  decriminalization:

In the Netherlands, marijuana possession for personal use remains illegal. It's just never prosecuted. And indeed this seems to be the case for all the European countries with relatively permissive marijuana policies...It would be nice if we could arrive at an ethically and logically consistent legal stance on drug use, but it may be that in practice that's very hard to do, and not actually very important. Basically, while Sarah Palin's position on this issue, as on many others, is semi-deliberately incoherent, it is in this case a semi-deliberate incoherence that has proven to be effective policy in many countries, and I'm not even sure it's the wrong stance on the issue.
