There is considerable debate in Australia concerning the effects of cannabis on driving and whether it has a causal role in traffic accidents. Sixty-seven cannabis users in Melbourne were surveyed and questioned at length about their patterns of cannabis and alcohol use and driving, and their attitudes regarding driving while intoxicated. Sixty percent of these participants use cannabis at least once every two days. These participants drive more frequently after using cannabis alone than after using cannabis with alcohol. In terms of the effects of these drugs on driving skills, these participants believe that cannabis with alcohol is much more dangerous than cannabis alone. The findings from this study are discussed in relation to legislative changes around cannabis and driving planned for Victoria, Australia.
