Great post. Nobody should be able to regulate what you can do with your own body. To this line: "If you follow the money you will see the alcohol and tobacco industries throwing millions into keeping cannabis illegal."
I think the existing black and gray markets for cannabis have actors with more to lose than the tobacco and alcohol industries. From what I've seen, lots of people use all three or some combination at the same time. For example, I used to only smoke cigarettes when I drank, and some of my friends smoked weed before drinking to avoid the inevitable nausea that results from over drinking, and they also smoked cigarettes while partying. The black and gray market actors in Cannabis on the other hand would be completely out of business if it was legalized for recreational use. Do you know if any research has been done on this?
