Pilot study of a social network intervention for heroin users in opiate substitution treatment: study protocol for a randomized controlled trial.

Background Research indicates that 3% of people receiving opiatesubstitution treatment (OST) in the UK manage to achieve abstinencefrom all prescribed and illicit drugs within 3 years of commencing treatment, and there is concern that treatment services have become skilled at engaging people but not at helping them to enter a stage of recovery and drug abstinence. The National Treatment Agency for Substance Misuse recommends the involvement of families and wider social networks in supporting drug users’ psychological treatment, and this pilot randomized controlled trial aims to evaluate the impact of a social network-focused intervention for patients receiving OST.
