    Social networks and substance use after transitioning into permanent supportive housing

    Drug and Alcohol Dependence

    Year: 2018

    Substance use remained relatively stable among participants over their first year living in PSH, although illicit substance use reduced somewhat at six months compared to baseline levels (from 18.5%–14.5%) and marijuana use increased slightly at 12 months (from 26.6% at baseline to 32.9%). Substance use among social network members was consistently associated with individual-level substance use, both cross-sectionally and longitudinally. Specific network substance use characteristics, such as proximity, location met, and social support, had differential relationships with particular substance types.

    These findings provide longitudinal evidence that changes within substance-using social networks are associated with subsequent changes in individual use and underscore the importance of interventions aimed at promoting positive social relationships for formerly homeless persons and improving PSH’s social environments.
