There is strong and consistent evidence that this package of harm reduction interventions significantly reduces injecting drug use and associated risk behaviours and hence prevents, halts and reverses HIV epidemics associated with injecting drug use. Conversely, there is no convincing evidence of major negative consequences of such interventions, such as initiation of injecting among people who have previously not injected or an increase in the duration of frequency of illicit drug use or drug injection.
