In this paper Moore & Dietze use data from their study of street-based injecting drug users and sex workers in the Melbourne suburb of St Kilda to challenge the dominant emphasis of drug policy in Australia. They remind us that while existing harm reduction strategies that encourage individual behaviour change should be continued, these measures need to be complemented and extended by further attention to the environmental aspects of drug-related harm. This is a timely call. Responses targeting individual behaviour change are relatively easy to implement and less politically challenging. However, if we are really serious about reducing drug-related harm in the Australian community, then broader systemic and structural barriers which undermine these efforts must be addressed.Simon LentonEditor, Harm Reduction Digest.
