“This study used prospective nationally representative cohort data from the Population Assessment of Tobacco and Health study (19,009 youth across 38,163 observations, ages 13–22).

Relative to states with illicit cannabis, residing in states where cannabis was legal for recreational use or medical use was associated with 1.449 (95% confidence interval [CI]: 1.285–1.635) and 1.198 (95% CI: 1.006–1.427) higher odds of cannabis vaping initiation, respectively. Though comprehensive indoor vaping bans were not related to cannabis vaping initiation, the associated odds of cannabis vaping initiation were 8.07 times higher (95% CI: 7.170–9.072) for youth reporting e-cigarette use during the past month.

Within US states that legalized adult use of cannabis, efforts are needed to prevent diversion of novel products, such as vaping devices, from legal marketplaces to adolescents. Prevention efforts for cannabis vaping should focus on youth who already use e-cigarettes.”
