This study examined the impact of prison-initiated methadone maintenance at 12-months postrelease. Males with pre-incarceration heroin dependence (n=204) were randomly assigned to: 1) Counseling Only: counseling in prison, with passive referral to treatment upon release; 2) Counseling +Transfer: counseling in prison with transfer to methadone maintenance treatment upon release; and 3) Counseling+Methadone: counseling and methadone maintenance in prison, continued in the community upon release. The mean number of days in community-based drug abuse treatment were, respectively, Counseling Only 23.1, Counseling+Transfer 91.3, and Counseling+Methadone 166.0, p <.01; all pairwise comparisons were statistically significant (all ps < .01). Counseling +Methadone participants were also significantly less likely than participants in each of the other two groups to be opioid-positive or cocaine-positive according to urine drug testing. These results support the effectiveness of prison-initiated methadone for males in the United States. Further study is required to confirm the findings for women.
