As previously reported on BoxingScene.com, Tyson Fury claims he has taken "lots of cocaine" over the past six months and does not know if he will see the year out, saying: "I hope someone kills me before I kill myself."
In a dark interview with Rolling Stone, the 28-year-old appears to confirm recent reports of a positive test for the drug and opens up on the depression keeping him out of the ring.
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 magazine.
In an interview the magazine says was 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."
Fury's comments could well be of interest and general concern to the British Boxing Board of Control, but it was unavailable for comment, as were Fury's camp. He did, however, claim he has been clean since the first of the month.
Fury, a member of the travelling community, believes there has been a witch-hunt against him ever since he dethroned Klitschko, taking his IBF, IBO, 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.
There is also another controversy hanging over his head. UK-Anti Doping (UKAD) had charged the champion, over a urine sample taken in February 2015, with a doping offence.
It was alleged the sample - taken nine months before Tyson Fury's defeat of Klitschko - contained traces of the banned substance nandrolone. Fury was provisionally suspended, but that ban has since been lifted, and his legal team said they would be suing UKAD over the allegations. His hearing will be held in November.
While Fury admits to using cocaine, he denies that he every used any type of performance enhancer. He doesn't know why his critics wants him stripped over using cocaine - stating to the magazine - "[cocaine] ain't a performance enhancing drug."
"No drugs at all [in my system when I was fighting], no drugs at all. I have never ever taken a drug to help me boxing in my life. Never took a performance enhancing drug ever. Never even took an aspirin for a cold. I'm a natural. The only person that can beat me is me," Fury said.
"I've been out, I've been drinking. I'm on the verge of becoming an alcoholic. I'm drinking Monday to Friday to Sunday. I can't, I can't deal with it, and the only thing that helps me is when I get drunk out of me mind and that's it. I don't tell lies, I've no need to tell lies. I've taken drugs, cocaine, on many many occasions for the last six months. Not to enhance my performance – cause I've not been performing."
