Toxicology reports obtained by TMZ have shown the cause of Scott Weiland’s death: an overdose on cocaine, MDA (a form of ecstasy), and alcohol. The report from the Hennepin County Medical Examiner also mentioned that heart disease and asthma were “significant” factors, as was Weiland’s “multi-substance dependence.” The former Stone Temple Pilots frontman had a history of addiction.

Weiland died at the beginning of the month, and was found on his tour bus before a show in Bloomington, Minnesota.
