Legendary rocker Stevie Nicks spent more than $1 million (GBP500,000) on cocaine during her hellraising heyday.
The Fleetwood MAC star consumed huge amounts of the drug during the 1970s and 80s and even thanked her dealer on the band's album credits.
She only kicked the habit during a stay at the Betty Ford Clinic, after a doctor warned her she would lose her nose if she continued to snort the drug.
Nicks says, "At $100 a pop - that's a gram - and we were the ones who were buying it for everybody else; not only us, but all our friends. I would say millions."
