Some countries have the death penalty for possession. If your hypothesis was correct, drugs wouldn't exist in those countries. Deterrents do nothing.<quoted text>
Crime is rampant because of people like you - that are soft on criminals.
Criminals feed off of the "understanding" of society.
And we as a society are not at all soft on crime. Most of us believe in retributive justice, and we have ridiculously harsh penalties for stupid things like drugs. Yet we abuse drugs at a higher rate than pretty much the entire world.
