STONE TEMPLE PILOTS Singer Failed Drug Test Within Past Two Weeks

STONE TEMPLE PILOTS singer Scott Weiland had entered a rehab facility within the past two weeks but left early after failing a drug test, according to Buddy Arnold, co-founder of the Musicians' Assistance Program, which helps provide treatment for musicians addicted to drugs and alcohol.

"The last time I saw him," Arnold told MTV.com, "I couldn't get him to sit down or look at anything, he's so wired all the time. He needs to be somewhere for quite some time so they can address what's wrong with him psychologically."

In addition to his struggle with addiction, Weiland suffers from bipolar disorder, a serious mental illness (also known as manic depressive disorder) for which he said he refuses to take medication due to its dulling effects on his personality.

Weiland, who was charged with cocaine and heroin possession in Los Angeles earlier this week, faces up to a year in county jail if convicted. A spokesperson for the district attorney's office told MTV that his prior convictions on drug charges in California could "more or less preclude him from being diverted" into a drug program to avoid jail time. He is scheduled to be arraigned on June 2.

Weiland, who recently cut two songs with three former members of GUNS N' ROSES and was widely believed to be the top candidate to land the lead singer slot in what's currently dubbed "THE PROJECT," has been arrested on drug charges twice before in California, in 1995 and 1997. He was also busted in New York in 1998, and the next year served prison time in Los Angeles after a heroin overdose that a judge found violated his probation. After his release, Weiland tried to go clean, but was arrested in Las Vegas in 2001 after an argument with his wife Mary over a prescription turned into a domestic violence charge. The Weilands filed for divorce last September.
