Federal tobacco 21 and young adult nicotine use: Quasi-experimental evidence on prevalence, cessation, and non-compliance from the NHIS.
When the US raised the legal tobacco purchase age to 21 in 2019, young adults aged 19-20 reduced their use of cigarettes and e-cigarettes by about 26-28% compared to slightly older adults. The law also showed signs of encouraging some young people to quit nicotine use entirely, though this effect was less conclusive.
