Trey got nabbed by the federalies with some pharmies. He likes his Zannies! Here's what The Smoking Gun said:
Former Phish frontman Trey Anastasio was arrested in December 2006 by upstate New York cops for driving while intoxicated and illegal possession of a variety of medications (Xanax, Percocet, and Hydrocodone) prescribed in someone else's name. Anastasio, 42, whose real first name is Ernest, was nabbed by Whitehall police just miles from the Vermont border following a traffic stop. He was charged with criminal possession of a controlled substance, DWI-drugs, and driving without a license.Trey has a new chapter in his E Hollyweird story. You're not really a rock star until you get a DWI or a drug bust anyway. More details in this article where Trey admitted to smoking hashish before driving.
