Using data from the California Civil Addict Program, the study tested hypotheses about the possible conditional nature of the process of maturing out of heroin addiction. Hypotheses were tested in a five-way contingency table using the log-linear model. Results show that maturing out of addiction with increasing age is inhibited by high levels of involvement in crime and drug dealing.
