ABSTRACT
The current study investigated the association between secondhand effects and personal consequences with substance use in a sample of rural college students (N = 412; 55.1% women; 92.2% white/non-Hispanic). The study extends the body of secondhand effects research by (a) investigating the association of marijuana use with the experience of secondhand effects; (b) examining the association of onset risk of substance use (< 18 years old) with the experience of secondhand effects; (c) exploring the multiplicity of experienced effects associated with substance use by employing a four-category typology that exhaustively represents exposure to secondhand effects and personal consequences. Bivariate and multiple regression analyses were used to evaluate the data. The majority of students (90.3%) experienced undesirable effects from substance use, with 15% reporting only secondhand effects, 28.5% only personal consequences, and 46.8% reporting both secondhand effects and personal consequences. Residing on-campus, onset risk, and past 30-day alcohol or marijuana use increased risk for experiencing personal consequences and the combination of secondhand effects and personal consequences. Secondhand effects are likely to compound the harm for substance users because they often experience both secondhand effects and personal consequences.
