Naomi Campbell has spoken out about her previous cocaine addiction - and about those that exposure stars for taking drugs.

Naomi, who went through rehab in 2001, told GQ recently that she first took cocaine in 1994 when she was 24 years old: “I was at a concert in a European country and I was offered cocaine.”

“It made me feel invincible. Like I could conquer the world. I was just completely over-confident, but it’s all a misconception because when you wake up the next day it’s all gone and you feel awful.

“And the more you take drugs, the more you want. And that’s how you become an addict.”

“I’ve not taken drugs for ages. I’ve put all that behind me.”

But even as she tried to deal with her addiction, her public status made it hard for her to deal with the problem and the Daily Mirror published photographs of her leaving a Narcotics Anonymous meeting in 2001. She added that her friend Kate Moss is in a similar position now: “She is hurting herself and when it’s exposed she doesn’t have the space or time to help herself because everyone is looking at her. It’s hard.”

“I don’t think anyone should be exposed for taking drugs. That person is ill, they are sick.”
