Lady Gaga admits she dabbles in drugs.
"My schedule is such that I don't get very much time to eat. But I certainly don't have an eating problem. A little MDMA [Ecstasy] once in a while never killed anybody, but I really don't do drugs," the singer, 24 -- who has been rumored to be on a baby food diet -- tells the UK Times Online. "I don't touch cocaine any more."
Continues Gaga, "I don't smoke. Well, maybe a single cigarette - with whisky - while I'm working, because it just frees my mind a little bit. But I care about my voice. The thrill of my voice being healthy on stage is really special. I take care of myself."
The "Telephone" singer says she stays sane by taking "prescription medicine."
"I can't control my thoughts at all. I'm tortured," she says. "But I like that. [Spanish poet] Lorca says it's good to be tortured. The thoughts are unstoppable -- but so is the music. It comes to me constantly."
Gaga says she has heart palpitations. "It's just from fatigue and other things. I'm very connected to my aunt, Joanne, who died of lupus. It's a very personal thing. I don't want my fans to be worried about me."
