What would happen if weed was legal?

That is a question with a lot of answers. In short, it would solve a lot of problems. You can find the full text of the major government commission reports that have tried to answer that question at http://druglibrary.org/schaffer/Library/studies/studies.htm These are the most comprehensive and definitive studies of the subject ever done. They all agreed that the marijuana laws were based on racism, ignorance, and nonsense. They all said the marijuana laws should have been repealed long ago because they do more harm than good.
