Meanwhile Marijuana for medical use is already legal in 19 states, not counting Colorado and Washington, and Washington DC for a total of 22. Marijuana prohibition enforcement costs the government 13.7 billion dollars annually, and puts well over 500,000 people in jail every year (sources cited below).
