Re: Supply and demand question about drugs.
It would be A, a increase in supply and demand. I think the supply would actually move more, as people would start growing their own weed. Demand would rise slightly, but I don't think non weed smokers would all the sudden decide to become smokers. The increase in demand would mostly come from the people who already smoke. For instance, I don't smoke weed, nor would I if it became legal.
