Heroin injection associated with respiratory disorder

This 5-year NIHR Maudsley BRC study followed a 62-year-old man with a 45-year history of opioid use who has been injecting pharmaceutical heroin (diamorphine) daily for several decades but who has not smoked or taken illicit drugs or alcohol for over 10 years. It saw heroin-induced slow and ineffective breathing, as well as apnoea.
