The article describes an approach to the treatment of cocaine dependent patients in which the patient's social network is used to bolster his attempts to achieve stable abstinence. The network is drawn from persons close to the patient, typically members of his immediate family or close friends, and is used for social support in assuring compliance with the treatment regimen and in undercutting denial. The function of the regimen is explained to the patient and network members: It is conducted to assure the patient's abstinence from the outset of treatment, to mitigate against the occurrence of slips, and to support reintegration into treatment should relapses to alcohol or drug use occur.
