A 12-year follow-up of a treated cocaine-dependent sample

The study examined long-term outcomes (mortality, substance use, mental health, employment, criminal involvement) among a cocaine-dependent sample. This 12-year follow-up study, conducted in 2002–2003, updates information obtained at intake and two face-to-face interviews conducted in 1990–1991 and 1991–1992 among 321 male cocaine-dependent veterans admitted to drug treatment in 1988–1989.At the 2002–2003 follow-up, 28 had died and 266 were interviewed. A mixed model examining the longitudinal relationships demonstrated that treatment was associated with lower levels of cocaine use over the 12-year follow-up period after entry into the index treatment and more stable recovery (i.e., continuously abstinent from cocaine for at least 5 years). Few measures at intake predicted stable recovery at follow-up: only being White (vs. being African American) and having greater confidence in ability to avoid cocaine use in high-risk situations.Individuals achieving stable recovery reported less psychiatric symptoms, criminal involvement, and unemployment during the year prior to the interview. Adverse outcomes were apparent for a significant number of cocaine-dependent users who continued to use cocaine for a long period.
