"The heart of the challenge is the possibility that things could be different: overdose is a public health problem that can be solved. Unlike many of the other leading causes of death, death from opioid overdose is almost entirely preventable,21 and preventable at a low cost.22 Opioids kill by depressing respiration, a slow mode of death that leaves plenty of time for effective medical intervention.23 Overdose is rapidly reversed by the administration of a safe and inexpensive drug called naloxone. Naloxone strips clean the brain’s opioid receptors and reverses the respiratory depression causing almost immediate withdrawal.24 A growing number of harm reduction organizations in the United States are offering overdose prevention programs that provide injection drug users with resuscitation training and take-home doses of naloxone.25"
