J Addict Dis. 2001;20(1):43-8. doi: 10.1300/J069v20n01_05.


Objectives: To investigate the 2-year outcome of the first 131 crack cocaine users who had been admitted for a period of inpatient treatment.

Design: Follow-up study of consecutive patients admitted between 1992 and 1994.

Setting: Inpatient detoxification unit of a public general hospital in São Paulo City, Brazil.

Participants: 131 consecutive crack cocaine users.

Measures: Reported crack use during last 12 months, incarceration and death.

Findings: After 2 years, 50 patients reported crack use in the last 12 months, 29 said that they had not used it during this period, 9 were in prison, 13 had died, 2 had disappeared and no information was available on 28.

Conclusions: Crack cocaine use seems to be associated with a high mortality rate and criminal involvement but about one-third of patients give up using the drug within 2 years of inpatient treatment.
