BERKELEY -- A high school teacher who was arrested and charged with LSD possession and drunken driving in December after a traffic stop in San Rafael is no longer employed in Berkeley schools and his teaching credential was revoked, officials said Wednesday.

Douglas Haight, 51, of Berkeley pleaded not guilty to all charges Jan. 16 and will reappear in a Marin County court Feb. 4. He was charged with two felonies -- possessing LSD and bringing it into the Marin County Jail -- and one misdemeanor count of DUI, the district attorney's office said.

"We were notified by the state that his credential had been pulled; it's automatic for something like that," said Berkeley Unified School District Spokesman Mark Coplan. "If you're charged, you get your credential pulled, and he was charged with a felony."

Coplan declined to say if Haight was fired, but added "he's no longer a part of the district here because he can't teach without a credential."

Contacted Wednesday, Haight declined to comment.

Haight worked as an adviser to high school students in Berkeley who are in the independent study program.

The case began Dec. 1 when San Rafael police stopped a Toyota Camry that went through a red light. After being arrested for DUI and going to jail, Haight turned in his belongings for storage, including a bottle of breath mint that was in his pants pocket, police said. A jail deputy suspected it might contain drugs, and the liquid tested positive for the hallucinogen LSD.
