>> If the U.S. spent even a fraction of its war on drugs budget on rehabilitation we would have far fewer addicts, not more.

Rehabilitation and legalisation are distinctiv issues. When someone talks me about legalisation I think of cannabis-like legalisation where corporations make a profit not rehabilitation clinics like in Portugal.

If the gov wants to put the drug dealers out of business they could offer free shots for users as a free/affordable medical service. Along with campaigns and hard work the usage may even drop.
