Decreased heroin availability in Sydney in early 2001.

AIM

To examine the veracity of reports of a substantial decrease in the availability of heroin in Sydney in January 2001.

DESIGN

Cross-sectional survey.

SETTING

Sydney, Australia.

PARTICIPANTS

Forty-one injecting drug users (IDUs) and 10 key informants (KIs).

FINDINGS

Almost all IDUs (93%) reported that heroin was harder to obtain at the time of interview (mid-February 2001) than it was before Christmas 2000 and KIs concurred. IDUs (83%) and KIs (70%) also reported that the price of heroin had increased since Christmas, and that the purity of heroin had decreased (IDUs 73%; KIs 80%). Almost all IDUs reported a reduction in their heroin use and a subsequent increase in other drug use, particularly cocaine, benzodiazepines and cannabis. Similar reports about IDUs came from nine of the 10 KIs. Over half the KIs reported an increase in both property and violent crime as a result of the heroin shortage. This crime was reportedly occurring mainly between heroin suppliers and/or IDUs. Reports from other Australian jurisdictions suggest that the shortage was not specific to Sydney.

CONCLUSIONS

The reduction in the availability of heroin provides a unique opportunity to investigate the impact of supply reduction.
