The present study evaluates the feasibility and preliminary efficacy of a community support intervention (CSI) designed to increase drug\u2010free social support and expand drug\u2010free network support.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Participants receiving methadone treatment and using illicit drugs (<jats:italic>n<\/jats:italic>\u2009=\u200933) were randomly assigned to a weekly CSI or education group for 12 weeks. CSI participants attended the group with a drug\u2010free family member or friend, and were scheduled to engage together in two community activities per week designed to meet drug\u2010free people. Education participants attended a weekly education group and were given two weekly written homework sessions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>CSI groups were well attended. CSI participation was associated with reduced conflict with the family member or friend, and with increased engagement in self\u2010help groups. No condition differences were observed in social network variables or urinalysis results, though four CSI participants (24%) compared to 0 education participants met criteria for substantial (&gt;75%) reductions in drug use.
