Resumo Aims. To examine transitions in the route of administration of cocaine and the variables associated with them. Design. A cross-sectional study undertaken between January 1996 and October 1997. Setting. Fifteen different services that offer treatment, counselling or assistance to drug users or HIV-positive patients in the State of São Paulo, Brazil. Participants. Two hundred and ninety-four current or ex-cocaine and crack cocaine users. Measurements. A structured interview schedule was developed consisting of 246 questions covering socio-demographic details, drug history, cocaine transitions and HIV-risk behaviours. Findings. Eighty-seven per cent of patients began using cocaine by snorting and 74% subsequently underwent a transition of route-68% towards smoking and 20% to injecting. Half of all transitions occurred in the first 3 years following initiation into cocaine use. Factors associated with transitions were: younger age at cocaine initiation, more frequent use at peak usage, initial use of cocaine by snorting or injecting, a lower level of scholastic attainment and experience with a wider range of drug classes. A cohort Effect was apparent with younger cocaine users and those who had begun using after 1990 being more likely to undergo a transition to smoking crack and less likely to start injecting. Conclusions, Cocaine transitions are very common and are usually rewards routes associated with a higher dependency potential and increased HlV-risk behaviour. Further research is needed to see if transitions can be prevented by early identification of potential cases.
