You love to hate her, but Miley Cyrus still happens to be one of the loudest voices for marijuana in the celebrity world right now. Most recently Cyrus stopped her show at the O2 Arena in London to give a bizarre and impassioned speech in favor of marijuana over cigarettes. She remarked, "It smells like someone's smoking in her, but you're not smoking the good stuff. Weed has never killed anybody; you guys know that, right?" She continued by telling the crowd that she used to smoke cigarettes for three years and during those three years it made her look older and smell worse -- thus preventing her from getting guys (and girls). But once she started rolling joints...that all changed. Check out her P.S.A. below:

Moral of the story: smoke out of your vaporizers, roll your joints in RAW papers, and get laid.
