The fight against smoking in the United States has seen significant progress over the years, with young adults playing a crucial role in driving the historic decline in smoking rates. A recent study conducted by researchers at the University of California San Diego, published in JAMA Network Open on April 25, 2025, highlights the positive trend in smoking cessation across the country. The study reveals that states with historically high smoking rates have experienced the most dramatic declines in smoking prevalence.
According to the lead author of the study, Matthew Stone, Ph.D., the rapid decline in smoking among young adults is a clear indication that the smoking epidemic is on track to come to an end in our lifetime. The researchers project that the national smoking prevalence will drop to under 5% by 2035. However, the slow progress in smoking cessation among adults over the age of 50, especially in states with high historical smoking rates, may prolong the burden of smoking-related diseases and death.
The study utilized data from the Tobacco Use Supplements to the U.S. Census Bureau’s Current Population Survey, analyzing responses from approximately 1.77 million individuals. The findings revealed that there were large differences in smoking prevalence across U.S. states in the 1990s and in 2022, with the most significant declines observed in states with high historical smoking rates. Disparities in smoking prevalence based on age, sex, race, and education levels persisted over the years, with young adults showing a larger decline in smoking compared to older age groups.
Since the 1950s, when the link between smoking and lung cancer was first established, national smoking rates have plummeted. In 1955, 56.9% of U.S. adults were smokers, but by 2022, that figure had dropped by 50%. The trend is expected to continue, with smoking rates projected to halve again by 2035. However, concerns have been raised about the tobacco industry’s success in recruiting a new generation of teenagers into e-cigarette use and nicotine addiction, highlighting the need for further research to assess the long-term impact of this shift.
In conclusion, while the decline in cigarette smoking is a significant public health achievement, efforts need to continue to address smoking cessation among older adults and prevent the uptake of alternative tobacco products among the youth. The study’s findings provide valuable insights into the progress made in reducing smoking rates across the country and emphasize the importance of sustained efforts to combat tobacco use and its associated health risks.
