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.”

After all these years, Naomi Campbell is still the baddest b@#ch in the game! The face, the body and the walk equals fire at the age of 36! Just the other day I was having a conversation about Naomi and someone dared to mentioned Tyra Banks in the same sentence! Blasphemy!
