The two follow-up interviews conducted after release from prison involved 56 and 40 participants, respectively. Results revealed some indication of an initial flurry of injecting risk behavior among participants soon after release; a minority reported injecting after release from prison. However, over time, patterns of injecting were variable. The incidence of sharing injecting equipment was low. The post-release risk behavior among the participants was generally low, perhaps contrary to expectation. In addition, neither community-based nor in-prison drug treatment programs had a major effect on patterns of drug use. The analysis concluded that caution is needed in making generalizations based on these findings. Overall, findings indicated that contact with in-prison or community drug services did not predict lower-risk behavior and that more enduring local factors may be just as influential on levels of risk behavior.
