Fashawn's new track might be titled "Medicine Man (Drug Free)," but don't let that make you think this isn't about drugs. In fact, it's the total opposite, as "Medicine Man" rides out with some synths, 808s, and lyrics dedicated to marijuana. As such, it's only right that Wiz Khalifa guests here. You can stream the Champagne & Styrofoam Cups joint (lulz) below.
