Changes in the characteristics of clients admitted to an Australian therapeutic community, "The Buttery", 1980-92.

Data are presented on the characteristics of clients admitted to an Australian therapeutic community, The Buttery, between 1980 and 1992. The typical client was a 28-year-old male with a primary opioid drug problem complicated by polydrug use, particularly of alcohol and stimulants. Prior treatment experience was common, with one in three having been enrolled in methadone maintenance treatment. The average age of clients increased by about 7 months per year, and there was an increase in the prevalence of alcohol, stimulant and polydrug problems over the period of study. There was also an increase in the exposure of clients to methadone maintenance treatment prior to admission to the Buttery. Overall, the characteristics of patients in this drug-free treatment programme were strikingly similar to those observed among patients in methadone maintenance treatment over the same period.
