Philip Seymour Hoffman was killed earlier this month by a deadly mixture of heroin, cocaine, and several other drugs -- this according to the NYC medical examiner.
The medical examiner just released the official cause of death -- listing "acute mixed drug intoxication" as the reason PSH died earlier this month.
The examiner lists heroin, cocaine, benzodiazepines (anti-anxiety) and amphetamines (uppers like Adderall).
Mixing heroin and cocaine is often termed "speedballing." It's the same mixture that killed Chris Farley, River Phoenix, and John Belushi.
