Back in high-school health class (AKA: “don’t do drugs, don’t have unprotected sex” class), they told us horror stories about how easy it was to OD on intravenous drugs, especially heroin. This included gory stories about how frequently drug users were found dead with the needle still in their arm.
Obviously, I know that shooting heroin is dangerous, but - is this true? I mean, is there a statistically significant occurrence of such instant death because of drug overdose? If so, how is it possible for a drug to kill someone so quickly?
