Thanks to the growing number of states that allow medicinal marijuana, California's Oaksterdam University has taught 7,000 students the law and science of marijuana and has a waiting list of 1,100 more. "Ten years ago I couldn't get a room full of people to talk about this," said chancellor Jeff Jones. "Now, people from across the country come to learn how to legally grow, distribute and profit with pot, even though it remains illegal under federal law."
