Media reports of heroin overdose spates: public health messages, moral panics or risk advertisements?

This article reports on an investigation of the public health utility of media messages concerning spates (temporal clusters) of heroin-related overdose (HOD) from the perspective of some injecting drug users (IDUs). In-depth qualitative interviews were carried out with a convenience sample of 60 IDUs, in the setting of two Needle and Syringe Programs in an Australian regional city (Geelong) between April and May 2000. Very few interviewees reported that they had personally experienced a spate of overdoses. None of the interviewees reported communicating the existence of a killer batch to other IDUs. No interviewees reported having changed either their injecting practices or the amount of heroin they used following such a media alert. Indeed, a substantial minority of the interviewees reported seeking out these stronger batches and participant narratives illustrate that, for a substantial group of interviewees, the media reporting of a hypothetical 'killer batch' of heroin may have implications for their drug-seeking and health-related behaviour. It was found that the accuracy of information available to IDUs is mixed and that the flow of information within this social network was slow. Findings demonstrate that media reporting of killer batches of heroin has little value as a public health strategy and provide an example of how some activities that are proposed as public health measures may in fact have the opposite effect.
