Ok, here is my beef with marijuana illegalization, despite me not being a smoker myself, I do not see much sense in declaring the drug "unsafe". Many times, "Above the Influence" advertisements would quite blatantly display completely incorrect information about marijuana. But why should I be pro-legalization if I myself do not partake in using it? I can sum it up in one word. Crime. People are going to use the drug (which is quite harmless if not a little senseless) regardless of regulations against it. My major gripe is that when people buy marijuana, they are essentially funding criminal organizations that participate in MUCH more illegal activities than mere marijuana trafficking. I am talking about woman-trafficking, weapons trafficking, violence, hard drugs trafficking and others. Even when legalization won't eliminate the threat completely, it will remove a large income to these criminal organizations. They WANT it to stay illegal, or else they would lose control of their product.
TL; DR Should be legalized to help weaken criminal organizations
