cocaine has medicinal uses?

Interesting HuffPo post about the politics and science of Plan B and marijuana laws (explains my subject line, too). The author suggests that pot be moved to a Schedule II drug, and makes a pretty convincing case for it. Not totally sure this will solve the problems (victimless criminals, a money sinkhole, etc.) related to marijuana illegality as well as fully legalizing it would, but maybe it's more realistic. I'd be interested to hear what you guys think.
