Why stop with weed? If you legalize all drugs, meth will disappear completely. Crack may even go away on its own too. We won't need the DEA anymore, which will save the government a bundle of money. There would be about half as many people going to prison. Addicts could be properly weaned off drugs in hospitals. There might be a few more car wrecks, but not as many as alcohol produces. I think things would be ok.
