World heavyweight boxing champion Tyson Fury has admitted to regularly using cocaine in the past few months after opening up about his battle with depression.
In a dark interview with Rolling Stone, the 28-year-old appears to confirm recent reports of a positive test for the drug.
Fury has not fought since taking Wladimir Klitschko's heavyweight belts off him last November, with their proposed rematch now cancelled twice at Fury's request.
Injury was cited the first time and ahead of an October 29 date Fury was declared medically unfit, with many in the boxing world fearing for his mental well-being.
Furthermore, on Monday he wrote on his Twitter account that he had retired, only to reverse the decision within three hours.
There had been no comment from Fury's camp on the cocaine reports - said to have come from a test done by the Voluntary Anti-Doping Association - but the fighter himself appears to have confirmed them to Rolling Stone.
In an interview the magazine conducted on Monday and before his retirement U-turn, Fury says: "Listen, I've done a lot of things in my life. I've done lots of cocaine. Lots of it.
"Why shouldn't I take cocaine? It's my life isn't it? I can do what I want. Yeah, I have done cocaine. Plenty of people have done cocaine as well."
Going on to explain why the fight has been called off again, he added: "I've not been in a gym for months. I've not been training. I've been going through depression. I just don't want to live any more, if you know what I'm saying. I've had total enough of it.
"They've forced me to the breaking edge. Never mind cocaine. I just didn't care. I don't want to live any more. So cocaine is a little minor thing compared to not wanting to live any more."
In further quotes which would appear to support the reports of a failed test, Fury added: "I never took other drugs, ever, in my life. I only started to take cocaine in the last few months."
Fury believes there has been a witch hunt against him since he dethroned Klitschko in their first meeting, taking his IBF, WBO and WBA titles.
He was stripped of the former when it became clear he would pursue a rematch and not fight mandatory challenger Vyacheslav Glazkov.
A member of the travelling community, Fury says there are people who want him thrown out of the sport and fears he may not live to see the end of the year as he battles his demons.
In the interview Fury talks about his decision to retire, something he later reversed on Twitter and followed up with a declaration of better health.
