We have previously reported (Scherrer et al., 2008, 2012) that offspring marijuana abuse/dependence is primarily associated with perceived drug use of friends and offspring nicotine dependence with perceived smoking of friends in models that accounted for perceived use of cigarettes, alcohol and drugs. The current finding that perceived weekly alcohol use by peers was only associated with the AUD class providers further support that type of substance use disorder is associated with type of perceived substance use. It is suggestive that social networks linked to substance use may be specific to those associated with drinking and those associated with drug use and smoking.
