She told Anderson Cooper that she doesn't say no when it comes to drugs, though now she mainly smokes weed.
“I smoke a lot of pot when I write music,” she said. “I’m not going to sugar-coat it for 60 Minutes that, you know, I’m like some sober kind of human being because I’m not. I drink a lot of whisky and I smoke when I write. I don’t do it a lot because it’s not good for my voice. I don’t want to encourage kids to do drugs... I have built up goodwill with my fans and they know all I am.”
