Philip Seymour Hoffman Died From Overdose Of Heroin, Cocaine, Prescription Drugs

The New York City Medical Examiner's Office has released the cause of Philip Seymour Hoffman's death.

The actor died of what the ME called "acute mixed drug intoxication." The drugs were heroin, cocaine, benzodiazepines and amphetamine.

Hoffman's body was found on February 2, with a syringe in his arm. Dozens of glassines of heroin were also found in his apartment, as were prescription drugs for anxiety, high blood pressure and attention deficit hyperactivity disorder.

TMZ notes, "Mixing heroin and cocaine is often termed 'speedballing.' It's the same mixture that killed Chris Farley, River Phoenix, and John Belushi."
