Olympic Medalist, Micheal Phelps, acknowledged that he engaged in “regrettable” behavior and shown “bad judgment” after a British tabloid published a photo showing Phelps smoking marijuana from a glass pipe.

Marijuana is a banned “in-competition” substance, so it’s unlikely that Michael Phelps will face any punishment.

“I’m 23 years old, and despite the successes I have had in the pool, I acted in a youthful and inappropriate way, not in a manner that people have come to expect from me. For this, I am sorry. I promise my fans and the public — it will not happen again.” This was Phleps statement posted by Octagon, his management firm, on his Facebook site.

Michael Phelps won 8 gold medal in the last Olympic game, the most medals won in Olympic history. Phelps will return to training and is hoping to compete in the Austin Grand Prix from March 5-7.
