For objectives 14, we investigated selection homophily and peer influence processes in terms of our smoking and vaping outcomes, namely: experimentally measured injunctive smoking and vaping norms (P2S2P2S9), experimentally measured descriptive smoking and vaping norms (P3Q1P3Q2), number of tokens donated to ASSIST/Dead Cool, self-report injunctive norms (IN1IN7), self-report descriptive norms scale 1 (DN1.1DN1.5), self-report descriptive norms scale 2 (DN2.1DN2.3), self-report smoking behavior, self-report smoking intentions, smoking knowledge, attitudes towards smoking, self-efficacy (emotional, friends, and opportunity subscales), perceived risks (physical, social, and addiction subscales), perceived benefits, perceived behavioral control (easy to quit), perceived behavioral control (easy to avoid), objectively measured smoking behavior, and smoking susceptibility (a binary outcome variable coded 1 if the individual was susceptible to commencing smoking and 0 if they were not susceptible to commencing smoking)

Having a graduate degree, an undergraduate degree, or education below the eighth-grade level demonstrated the lowest prevalence rates of smoking
