The idea
Opioids relieve pain and produce euphoria by binding the receptors the body's own endorphins use.
In practice
Prescribed opioids and heroin act at the same receptor sites, differing in delivery speed and dose control.
Where people slip
Tolerance to euphoria outpaces tolerance to respiratory suppression, which is the mechanism behind fatal overdose.
