title: Route of administration and adverse effects of amphetamine use among young adults in Syndney, Australia.
abstract: The relationship between route of administration and the adverse effects of amphetamine use (dependence symptoms, treatment-seeking, adverse psychological symptoms and violence) were examined among 231 Australian amphetamine users, half of whom usually injected amphetamine. Although 87% of users were recruited from non-treatment sources, a third had experienced symptoms of dependence on amphetamine, and a third had experienced an amphetamine-related health problem for which one in four had sought medical attention. There was also a high prevalence of psychological symptoms, such as depression, anxiety, paranoia, hallucinations and violence which were related to frequency of amphetamine use, and use by injection. Amphetamine users need to be better informed about the potential adverse effects of amphetamine use, and about ways in which they can reduce their risks of experiencing these harms by avoiding injecting use, and the regular use of high doses of amphetamines.
