Hoffmanâ€™s death in his Village apartment earlier this month was an accident and due to an â€œacute mixed drug intoxication,â€ including heroin, cocaine, benzodiazepines and amphetamine, the office said. A speedball is the intravenous injection of cocaine with heroin or morphine in the same syringe. Benzodiazepine is best known as an anti-anxiety medication and is commercially marketed as Valium. The deaths of comedians John Belushi and Chris Farley, baseball player Eric Show and several rock performers has been blamed on speedballs. A deadly mixture of drugs was suspected in Hoffmanâ€™s death at age 46 after police found dozens of bags of heroin and prescription drugs inside his apartment. A needle was stuck in the arm of the Oscar-winning star of the 2006 film â€œCapote.â€ The exact composition of the fatal injection was not known until tests led to Fridayâ€™s announcement. Hoffman had overcome the drug addiction he developed as a college student but relapsed after a period of more than 20 years when he began taking heroin and prescription drugs in 2012. He spent 10 days in a drug rehab center in 2013 and claimed he had kicked the habit again.
