A proverbial cocktail of drugs has been found on Scott Weiland's tour bus, where the celebrated singer passed away on Dec. 4. It was initially revealed that cocaine had been discovered aboard Weiland's bus, but now an additional six or seven drugs have been added to that list.

A toxicology report isn't expected to be released for another four to eight weeks, so we can't say for sure if the substances found belonged to Scott Weiland or contributed to his death, but the singer did have serious battles with addiction for over two decades.

TMZ reports they've acquired a copy of the search warrant drafted to inspect Weiland's bus and it details the substances in question. Along with two bags of white powder, which tested positive for cocaine (and briefly landed Weiland bassist Tommy Black in jail for possession), a generic version of Xanax, two different brands of sleeping pills, Viagra, Buprenorphine (a synthetic opiate painkiller) and Ziprasidone (used to treat bipolar disorder and schizophrenia) were all inside Scott's bus. A bag of a green, leafy substance was also taken into evidence.

According to TMZ, all of the substances listed above were found in Weiland's back bedroom of the bus, where Scott's body was reportedly discovered.

The outpouring of tributes for Scott have come in droves, including ones from his former bands Stone Temple Pilots and Velvet Revolver, who Weiland was unfortunately unable to reunite with before his death, despite his repeated desire to do so.
