Hillary Clinton supports the use of cannabis for medicinal purposes under appropriate circumstances and thinks medical marijuana should be researched, she said in a Tuesday interview with CNN's Christiane Amanpour. Clinton said she's taking a wait and see approach to recreational use. At the risk of committing radical candor, I have to say I think we need to be very clear about the benefits of marijuana use for medicinal purposes, Clinton said on CNN. I don't think we've done enough research yet, although I think for people who are in extreme medical conditions and who have anecdotal evidence that it works, there should be availability under appropriate circumstances. - CNN
