How Do Drug Overdoses Happen?Last Updated: Monday, November 6, 2017
(National Institute on Drug Abuse) When a person dies due to a drug overdose the medical examiner or coroner records on the death certificate if the overdose was intentional – purposely self-inflicted (as in cases of suicide) – or unintentional (accidental).
Unintentional drug poisoning deaths can happen when a drug or drugs are taken on purpose (or mixed together). They can also happen when a drug or drugs are accidently taken or given to a person in the course of a medical procedure. Total overdose death numbers also include cases where drugs are given to a person in a criminal act (a homicide, if a death occurs.) With most drugs, there are more accidental deaths than suicides or homicides.
Some overdoses happen when people leave drug treatment. During treatment, a person goes through a detoxification (“detox”) process---getting the drug out of the body. If a person has gone through detox, and then takes the same amount of drugs they took before, they can overdose because the body is no longer used to the same dose.
