Jamie Wachtel, widow of ex-Stone Temple Pilots singer Scott Weiland, is denying any speculation about her husband’s drug use. Although Weiland, 48, had a long history of struggling with addiction, Wachtel insists that he was clean prior to his death Thursday night.

TMZ broke the news Friday morning that Weiland was found dead on his tour bus in Bloomington, Minnesota. The musician was in the area to perform at the Medina Ballroom with his band, Scott Weiland & the Wildabouts. A statement on his official Instagram account explained that he “passed away in his sleep.” A later report from TMZ stated the cause of death as cardiac arrest.

Since news of Weiland’s death, sources have come forward stating that his friends were worried that he had fallen off the wagon again. There were also reports about drugs being found on the tour bus. However, Wachtel told TMZ that her husband has not been involved with drugs for some time. According to his wife of two years, the band made a “pact” not to do drugs.

Weiland “was the best he has ever been,” she said.

Weiland’s former publicist, Diana Baron, added to Us Weekly that Wachtel “saw the absolute best in him.”

Weiland and Wachtel, a photographer, met on the set of his music video, “I’ll Be Home for Christmas,” in 2011. They got engaged in 2012 and wed the following year on June 22. He had two children from his first marriage.

Prior to his relationship with Wachtel, Weiland had a very public battle with drugs and alcohol. According to Billboard, he was convicted of buying crack cocaine in 1995, and was arrested for DUI in 2003 and 2007. In 2007 he also reportedly entered a rehab facility for heroin use.
