Scottish cocaine users: wealthy snorters or delinquent smokers?

Ninety-two cocaine users were interviewed in Scotland. Most were middle-class nasal users, also used other drugs and generally gave cocaine a positive rating. One half of them had at some time used cocaine more than once a week. For some, this period lasted some months, when as much as 30 'lines' of cocaine were used per day of cocaine use. More of these heavy users reported adverse effects of cocaine than was the case for light users. Nonetheless, most heavy users had reduced their use by themselves to the point that their current cocaine use was no different from that of light users. Possible explanations for this apparently spontaneous reduction are discussed.
