From a purely cost standpoint I honestly don’t see how treatment programs would cost more than than the war on drugs.
Just think of the costs to house one prisoner, multiplied by the amount of prisoners in jail for minor drug offenses. Multiple police agencies who do nothing but drug busts. All of the associated court costs to process minor drug offenders.
The war on drugs has cost hundreds of billions of dollars and there is no evidence of any positive effect.
Personally I would legalize everything that can be grown naturally, and keep harsh penalties for manufacturing chemical drugs, aka meth and acid.
I agree.
