5. Why not free beer?
The difference between booze and drugs is the fact we don’t have a widespread illegal trade in alcoholic beverages that is fueling crime (unlike during the Prohibition).
My primary interest is crime reduction. For this, we must target the source of this crime. Cost reduction to government agencies is only secondary. If the current drug cartels switched to alcoholic beverages, they will have to compete against established producers - odds are they won't be able to compete - hence no need for free booze (sorry guys).
Why would drugs be any different? When legalization occurs won't the widespread illegal trade cease to exist?
Similarly, with the legalization of narcotics crime would be reduced almost to nothing. And the price would come down a great deal. That is until the government goes through a few tax hikes ala cigarettes to get the price back up to combat "teen use".
If a drug addict is a drug addict is a drug addict, then regardless of the drug of choice they should be provided free drugs under your plan. Unless you are of the mind that some drug addicts are more worthy than other drug addicts solely because of their drug of choice.
