...be it resolved that:
The United States spend Billions!! of dollars per year on the War on Drugs. Total reduction in drug use: 0.
Obviously there are problems with drugs, big problems. The Real Problem isn't drug use itself, but addiction and the way society deals with drugs. Drugs are shoved into the shady corners of life, of course there will be crime related. Three's crime enough in those areas anyway, drugs are merely an exacerbating factor.
If drugs were legalized (aside from ones which cause direct, personal, incontrivertable harm), this would no longer be the case. People would enjoy them with impunity and they would be awarded no greater affect than soda, cigarettes, or sugar-laden junk food. For the most part, drugs cause no problems, the War on Drugs causes problems. I don't know if you've ever tried any, but it's a fairly personal experience. A few stragglers aside, most drug use wouldn't be out in the open even if it were legalized.
