A Traverse City district judge has taken an indefinite voluntary leave of absence after being spotted smoking marijuana during last month's Rolling Stones concert at Ford Field, Local 4 reported.

A woman reported seeing District Judge Thomas Gilbert smoke a marijuana cigarette being passed down a row at the concert.

The Traverse City Record-Eagle newspaper published a written statement from Gilbert on Friday.

"I broke the law by twice puffing on a marijuana cigarette during a rock concert," Gilbert wrote. "I deeply regret this error in judgment, for I have let down my fellow judges, the court staff, my family, and the community."

Gilbert's leave became effective on Wednesday after he admitted to the drug use, the newspaper reported.

The judge is expected to be on voluntary leave until at least Nov. 15.
