Happiness and Health Study

Happiness and Health Study logo

H&H is part of the Tobacco Center of Regulatory Science (TCORS) Population Core, which aims to understand the use and health effects of specific e-cigarette products across populations. More specifically, the H&H study aims to identify novel risk factors for adolescent and young adult substance use and examine mental and emotional health, and other health behaviors.

Participants in H&H were recruited in 9th grade from 10 high schools in the Los Angeles metropolitan area (N=3396). Data were collected every 6 months through high school, and we have completed three additional waves of follow-up post-high school. Data collection is planned annually through 2022.
