Scott Weiland, the former Stone Temple Pilots frontman, died of a toxic combination of drugs and alcohol, the Hennepin County coroner said Friday.

Weiland, 48, died of “mixed drug toxicity,” the coroner’s report said. Cocaine, alcohol and methylenedioxyamphetamine (MDA) were found in his bloodstream. MDA, also known as “sally” or “the love drug,” is chemically related to the drug ecstasy.

The report noted “other significant conditions,” including atherosclerotic cardiovascular disease and a history of asthma and multisubstance dependence.

Weiland’s death is considered accidental.

He was found dead Dec. 3 in his tour bus at the Country Inn & Suites at the Mall of America in Bloomington.

Police said cocaine was found in the bedroom of the vehicle.

Weiland had been scheduled to play a tour date in Rochester.

He had fronted the San Diego-launched Stone Temple Pilots, best known for the hits “Plush” and “Interstate Love Song.” Stone Temple Pilots would go on to be one of the bestselling rock acts of the mid-1990s.
