The paper reports the findings of survey research recently completed in Melbourne, Australia, among a sample of 455 club and rave festival patrons. This research aims to provide a clearer account of the prevalence of drug driving within such settings in Melbourne, as well as identifying relevant 'predictors' of this drug driving. Just under half of the sample (48%) indicated that they had driven a motor vehicle within four hours of consuming an illicit substance at least once in the past year; 22% of respondents reported driving while 'knowingly intoxicated' in the previous year. Fifteen percent reported such behaviour 'several times' or more in this time. Relatively permissive attitudes towards drug driving, coupled with higher than average prevalence of drug driving in one's peer group, were found to be significant predictors of drug driving. So too was the reported frequency of the use of cannabis and ecstasy, and the propensity to use these substances in 'rave' and 'party' settings. Given the levels of drug driving revealed in this study, the paper closes with a series of recommendations regarding the design and delivery of more effective anti-drug-driving strategies within rave and club settings.
