I'm tired of the US thinking that military forceful action is the way to resolve conflicts, especially the way to win the "war on drugs." We should be much more effective at reducing drug addiction if we realized that it's not so much about the drugs, it's about our growing culture of conflict and emotional avoidance. When a population lets itself feel sadness, feel pain, and reinterpret conflicts from the assumed "they don't care about me" to "they care more about me than I may ever realize," then I am willing to bet the drug industry will shrink significantly.
Punishing those who sell drugs often just perpetuates this idea that punishment resolves conflict, which I'm very willing to bet actually _increases_ our tendency to be addicted to drugs.
