Golfer Dustin Johnson said in a magazine interview that cocaine is not the reason he chose to sit out the last six months to get his life in order.

"I did not have a problem," Johnson told Sports Illustrated when asked about cocaine. "It's just something I'm not going to get into. I have issues. But that's not the issue."

Johnson said in August that he was taking a leave of absence from the PGA Tour to seek professional help for what he called "personal challenges." reported that he had failed a drug test for the third and time and had been suspended. The PGA Tour denied he had been suspended.

The interview was the first for Johnson since he took his leave of absence. He missed the final major, the FedEx Cup playoffs and the Ryder Cup. He was not expected to return until his fiancée, Paulina Gretzky, had their first child. That child, a boy, was born Monday morning, making hockey great Wayne Gretzky a grandfather for the first time.

Johnson is an eight-time winner on the PGA Tour. He said he didn't go to rehab during his break from golf, instead hiring a team of experts, such as a life coach, to help him understand how to get the most out of his talent. Johnson is regarded as one of the best American players and the most athletic.

He said he learned he didn't handle stress the right way.

"My way of getting rid of it was drinking or partying," he told the magazine. "Yeah, that might work for that day or the next week, but eventually everything keeps piling up."
