FORT EDWARD, N.Y. (AP) – Arrested on drug charges during a Dec. 15 traffic stop, former Phish singer Trey Anastasio pleaded not guilty Tuesday and was released on bail.

Anastasio, 42, of Richmond, Vt., is charged with felony counts of illegally possessing prescription painkillers and driving while impaired. He is also charged with possessing heroin and an anti-anxiety medication prescribed for someone else, which are misdemeanors. He could get 14 years in prison if convicted on all counts.

Attorney Steve Coffey said Anastasio has a drug problem and is seeking treatment. He attended a 28-day treatment program in January and is attempting to overcome his addiction, Coffey said.

Coffey also said Anastasio instructed him not to fight the charges. Anastasio and his wife Susan left without commenting to a crowd of media.
