What this research studies

You'll be invited if you are a high school student in participating Mexican schools and will be followed over 2.5 years with six surveys. Each survey will ask about your cigarette and e-cigarette use, who your close friends are, who you interact with online, and you'll complete short choice exercises about product flavors and preferences. Researchers will map both friendship and online interaction networks and use computer simulations to see how use spreads through different kinds of social ties. The team will compare how strong friendships versus weaker online ties affect starting and progressing in vaping or smoking and model how different school or policy actions might change those patterns.

Who could benefit from this research

Good fit: Ideal participants are Mexican high school students willing to complete six surveys over 2.5 years and answer questions about their friends, online contacts, and nicotine product preferences.

Not a fit: Adults, children not in high school, or teens outside the participating Mexican schools are not included and would not directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could help schools and policymakers design better ways to prevent teen vaping and smoking by targeting the right social networks and product rules.

How similar studies have performed: Previous school-based network interventions have reduced bullying and cigarette use, but applying these network approaches to the recent rise in e-cigarette use and online interaction networks is newer.
