I agree, cocaine is not #1 by volume. I was talking about terms of money. Prescription drugs will always be #1 followed by weed. When you talk about opiates, that is too wide a pool. Heroin is different from oxy and other opiate-based painkillers.

You're right the smart thing to do is to legalize, regulate, and tax weed like alcohol and tobacco. There is also a prison-court-police system that depends on creating criminals that doesn't want it legalized. I don't think weed is totally harmless as some claim, but it certainly isn't bad enough to put people in prison over.
