IntroductionMany jurisdictions have implemented different regulatory strategies to reduce vaping among youth. The objective of this systematic review is to synthesize the evidence of the effectiveness of different regulatory strategies for preventing and reducing nicotine vaping among youth.MethodsFive electronic databases were searched from January 1, 2004 to July 17, 2022 for primary studies examining state/provincial or national regulations targeting vaping among youth (aged 12-21 years) in high-income countries. The primary outcome was vaping prevalence. Included studies were qualitatively synthesized through systematic review.ResultsThe systematic review included 30 studies. There was insufficient evidence to recommend age restrictions (n=16), restrictions on location of use (n=1), and mixed/combined regulations (n=3). Flavor bans (n=4), sales licenses (n=2), and taxation (n=2) were generally shown to be associated with decreased rates of youth vaping. Warning labels (n=2) were associated with a decreased desire to initiate vaping. Included studies had moderate-to-serious risks of bias.DiscussionAlthough several regulatory interventions have been shown to be effective at reducing vaping among youth, evidence is insufficient to recommend a specific type of regulation. Regulatory authorities could implement various regulations targeting the price, accessibility, and desirability (i.e., flavors and packaging) of E-cigarettes.Copyright © 2023 American Journal of Preventive Medicine.
