A lot of comments about why decriminalization of drug use is a no brainer. I'd like to point out that it's not that simple. From what I understand from different "experiments" like Portugal, it's a lot depending on context (eg culture) and how it's done. For example, easier access (lower taxes) on alcohol caused a rise in alcoholics and alcohol related deaths in Finland). Not everyone living in Colorado is happy about the outcome there either (sorry for no references, but please look it up if you'd like).

I'm not saying it shouldn't be done but like a startup venture, an idea is worth very little and the environment/market + how it's realized makes all the difference!
