London (ANI): American musician John Mayer has defended his decision to sing about smoking marijuana in his new single. Mayer, 32, is releasing 'Who Says" as the first song from his new album 'Battle Studies", which boldly begins with the question, “Who says I can"t get stoned?"

And he hopes his controversial lyrics will spark debate among listeners as to why the drug has yet to be legalised in the U.S. “It"s not a dirty word. It"s not a curse word. It"s a presentation of an idea that makes people think a little harder about what they"re listening to, which I don"t think is the worst thing in the world," the Daily Star quoted him as telling PopEater.com.
