New research, published in Tobacco Control , from the Prevention Research Center of the Pacific Institute for Research and Evaluation investigated the effects of California’s 2016 law that raised the minimum tobacco sales age to from 18 to 21 (T21) and found evidence that the new law has had positive public health effects on students from across California.

Specifically, results show that T21 was associated with:

  • Reduced prevalence of lifetime smokeless tobacco and e-cigarette use, and past month smokeless tobacco use in the overall student population.
  • Increases in prevalence of past month e-cigarette use.
  • Reductions in lifetime and past-30-day use of all tobacco and nicotine products among Latinx youth.
  • Differential, but positive public health effects for other racial and ethnic groups.

Says lead author, Joel Grube, MD: “Our research shows that raising the tobacco purchase age to 21 years is a recommended strategy to reduce adolescents’ tobacco and nicotine use.”
