In fact, when he was asked specifically about cocaine use in a new interview with Golf.com, Johnson said, "I did not have a problem. It’s just something I’m not going to get into. I have issues. But that’s not the issue.”
So, what WAS the issue? Sounds like booze played a role ... with Dustin saying he's cut back on the alcohol and is trying to learn how to drink in moderation.
"I don’t miss waking up with a hangover, and I didn’t drink very often. It was just when I did it was a little too much."
DJ says he even had a $1,000 bet with Wayne Gretzky and eight other pals to see who could go into January without drinking.
Dustin is also adamant he never entered a rehab center -- but says he did hire a team of experts, including a life coach, to help him get his life back on track.
He's expected to return to the PGA circuit next month.
