in fact legalization of ONLY marijuana, regulation of it and legal production and sale of it and its by-products (count in all hemp-derived products as well) can do much good for the nation

1. Save up a gigantic amount of money used on war on marijuana
2. Focus on other crimes better
3. reverse convictions of simple possession marijuana offenders, currently costing federal and state govts and taxpayers money whether in programs or in jails
4. Quit focusing on corn-ethanol, make fuel alternatives from hemp >>> this will lead to a drop in food prices overall and also gasoline (currently benefiting only a few states and a few bunch of lobbying farmers, they can simply switch the crop)

just imagine if in the current situation, we can pioneer in hemp-derived fuels and impose a worldwide monopoly for a while, saving money by avoiding buying foreign oil, creating jobs here at home and going for exporting as well

this wont "solve" the problem, but it will be of much help
