Drug use functions predict cocaine-related problems in young people

Over the last decade, concern about young people and stimulant drugs has primarily focused on the use of amphetamines and ecstasy. In the United Kingdom, this concern has recently expanded to include the use of cocaine hydrochloride (powder cocaine). This study examined patterns of illicit substance use. with a particular focus on cocaine consumption, among a sample of 364 young drug users aged between 16 and 22 years, The sample was recruited using snowballing methods and respondents were interviewed in informal settings by peer interviewers. Over half the sample reported lifetime use of powder cocaine and just over 40% of these had used crack cocaine, A seven-item scale was used to measure cocaine-related problems. The three most common problems endorsed by the cocaine users cr ere impaired control, 'prioritizing spending money on cocaine over other things' and being pre-occupied with using. In a multiple regression analysis, 50% of the variance in cocaine-related problem scores,vas predicted by the perceived functions for cocaine use, the number of times of lifetime cocaine use and the total number of days of recent stimulant use. Use of cocaine to alleviate depressed state or negative mood was the most powerful predictor of cocaine problems. The inclusion of a functional appraisal component could be usefully incorporated in further research studies and in service assessment protocols for young people.
