FORT EDWARD, New York - Former Phish frontman Trey Anastasio received a reduced sentence of three years' probation for a drug conviction after he successfully completed a counselling and treatment program.

The musician had pleaded guilty to a felony charge for possessing painkillers without a prescription during a traffic stop in December 2006. He faced up to three years in state prison if he failed the drug program, which he began in April 2007.

The 43-year-old's guilty plea was reduced to a misdemeanour Wednesday because he will graduate the drug program next month and has completed community service. He spent two days in jail in January for missing a scheduled drug counselling session.
