Compiled annually by the Australian Crime Commission (ACC) with data gathered from all state and territory police services, the Australian Federal Police, the Australian Customs Service, and the state and territory analytical laboratories, this report provides a national picture of the illicit drug market in Australia and is the only report of its kind. Data is offered by drug class and, in most cases, includes domestic and international trends and an analysis of the national impact. Main drug classes analyzed include amphetamines, phenethylamines, cannabis, heroin, cocaine, and other drugs such as mushrooms and ketamine. Key findings for the 2003-2004 report indicate an increase in demand for amphetamine-type stimulants, which are associated with high levels of harm to individuals and the environment. Demand for phenethylamines, such as MDMA, also continues to rise in Australia and recent seizure data suggest its local production and availability are increasing as well. Cannabis production and availability remain at high levels throughout the country while estimates on heroin seizures are the lowest they have been for the past decade. Estimates on the price, availability, and seizures of cocaine indicate that the market for cocaine remains stable in Australia while a number of other drugs are becoming more prevalent, including steroids, anaesthetics, and pharmaceuticals obtained for illegal use.
