A recent study published in JAMA Health Forum on December 20, 2024, underscores the significant public health benefits associated with the early adoption of Tobacco 21 (T21) policies.

Conducted by Jamie Tam, M.P.H., Ph.D., and colleagues from the Yale School of Public Health, the research examined the impacts of T21 policies on smoking-attributable mortality.

The study analyzed data from all 50 U.S. states and the District of Columbia, focusing on smoking initiation, cessation, and mortality rates from 2005 to 2024, with projections extending to 2100.

The findings suggest that comprehensive enforcement of T21 laws across the nation could prevent up to 526,000 premature deaths and yield approximately 13.3 million life-years gained by the year 2100.

In specific states, the early implementation of T21 policies shows promising results; for instance, California is projected to avert over 27,000 premature deaths by 2100, while Kentucky's efforts could save around 15,000 lives.

Massachusetts is also expected to see a reduction of 8,000 premature deaths, largely due to municipal T21 policies that effectively cover most residents.

Conversely, Wisconsin, which currently lacks state or local T21 policies, could prevent up to 10,000 premature deaths if federal T21 regulations were enforced.

Even with just state and local policies in place, the study indicates that 442,000 premature deaths could be avoided, emphasizing the potential health benefits of T21 initiatives.

The authors of the study call for urgent action from federal and state lawmakers to enhance the enforcement of T21 policies in order to maximize these health benefits.
