Methadone, IV use and crack


Methadone is used world-wide as a first choice treatment for opioid dependency, and higher doses are generally associated with higher rates of treatment retention, heroin abstinence and wider improvements in health and social life.

Research suggests that heroin use in methadone treatment is more common for dual users of heroin and crack/cocaine. In addition, more frequent intravenous (IV) use and poor technique increase the risk of health complications. Dual users injecting drugs might therefore be at higher risk of physical health deterioration even when accessing opiate substitution therapy.


To explore the physical health and heroin use of IV drug users in methadone treatment.
