The singer said that although she tried various substances, she didn't feel happy taking them because she wanted to look after her body.
The star, 56, told Mojo magazine: 'My problem is I don't have the stamina to take drugs. I feel terrible afterwards. I'm destroyed for days and days. I can't do anything and I don't want that inconvenience in my life. So I don't feel it's worth the price you have to pay,' she said.
'Even when I was younger and in my 20s, trying this and that....I mean, I never really did that many drugs,' she told the mag.
'I'm too big of a p***y. Also, I'm a dancer and I don't want to destroy my body. I want to feel physically good. So it never came naturally to me to get out of my brains or get so high that I couldn't get out of bed for three days. And that's what happened to me if I did anything.'
