Miley Cyrus isn't afraid to speak her mind, and when her mind is set to the topic of drug use, then she is even more open and revealing than usual. So when the topic came up in her recent interview with Rolling Stone, you can bet that the 'Wrecking Ball' singer wasn't going to hold back on the details of her drug-related exploits.

The interview, which was accompanied by a racy photo-shoot that included a topless front cover picture, saw Miley discuss her love of marijuana and MDMA, two drugs that she has already admitted to using, the latter being mentioned in her song 'We Can't Stop.' But her interview wasn't all pr-drug use though, as she went on to discourage cocaine use, and discuss her hopes for upcoming release Bangerz.

"One time I smoked a joint with peyote in it, and I saw a wolf howling at the moon," Cyrus told Rolling Stone contributor Josh Eells. She continued, "Hollywood is a coke town, but weed is so much better. And Molly, too. Those are happy drugs - social drugs. They make you want to be with friends. You're out in the open. You're not in a bathroom."

Speaking of cocaine, she said, "I really don't like coke. It's so gross and so dark. It's like, what are you, from the '90s? Ew."

There was also time to clear up her obsession with sticking her tongue out all the time, a reasoning that was actually quite understandable. She explained, "I just stick my tongue out because I hate smiling in pictures... It's so awkward. It looks so cheesy. Now people expect it -- like, 'Put your tongue out!' It's just easier that way. Taking pictures is so embarrassing."

It was an engaging and revealing chat, where much more than drugs and tongues were discussed. By the end of the interview though, Miley demonstrated that she can do more with her tongue than lick sledgehammers and try to reach her chin with it; she can also strike up an engaging conversation too. Who would have thought! The full discussion with Miley is available at RollingStone.com.
