The harm caused by the war on pot extends beyond its 15 million prisoners; its cost has exceeded a trillion dollars.
For almost 40 years, the United States has waged a war on its own citizens who have used marijuana as a part of a drug culture originally encouraged by the government. The war was commenced despite the government's own findings that marijuana posed less of a risk to American society than alcohol, and that the greatest harm that would result from criminalization would be the injury caused to those arrested for possession and use. The harm caused by the war extends beyond its 15 million prisoners; its cost has exceeded a trillion dollars, and it has benefited only those who profit from the illegal cultivation and sale of marijuana. see Government Responsibility for the Drug Culture
