I've always been for decriminalization of drugs. Just look at what happened with alcohol prohibition. Alcohol illegal? Violent crimes, gangs etc. Alcohol legal again? All that shit went away again.
Some time ago Portugal decriminalized drugs and the results are in: War on drugs is a massive failure, decriminalization is vildly succesfull.
