This study presents the first regression discontinuity evidence on the effectiveness of e-cigarette MLPA laws. Using data on 12th graders from Monitoring the Future, we obtain robust evidence that federal and state age-18 MLPAs decreased underage e-cigarette use by 15-20% and frequent use by 20-40%. These findings suggest that the age-21 federal MLPA could meaningfully reduce e-cigarette use among 18-20-year-olds UR - https://www.nber.org/papers/w30614 UR - http://dx.doi.org/10.3386/w30614 ER -
