As a Soldier I know very well how a gun in a good-guy's hand can counter a gun in a bad-guy's hand, that's our job, but how does cocain in a good-guy's hand counter cocain in a bad-guy's hand? I don't see how increasing availability of hard drugs is going to solve any problem.
For people worried about prison population size, my answer to that is to exicute repeat offenders who can't or won't complete rehab and stay off it. We don't need that kind of person on the planet. We have enough problems with jihadfags trying to blow everything up to put so much effort into dealing with coked up loosers.
