Researchers from the University of California San Diego have found that local sales bans on flavored tobacco in California are associated with reduced youth vaping over time without increasing cigarette smoking. The findings, based on an analysis of more than 2.8 million middle and high school students, were published in JAMA Health Forum.

Why it matters

Flavored tobacco products have been a major driver of the youth vaping epidemic, with concerns that banning these products could lead young people to switch to more harmful cigarettes. This study provides evidence that local flavor bans can be an effective public health strategy to curb youth e-cigarette use without unintended consequences.

The details

The researchers analyzed data from the National Youth Tobacco Survey, which includes responses from over 2.8 million middle and high school students across the country. They found that in California cities and counties that implemented local bans on the sale of flavored tobacco products, youth e-cigarette use declined over time compared to areas without such policies. Importantly, the study did not find any evidence that these flavor bans led to increased cigarette smoking among young people.

What’s next

The researchers plan to continue monitoring the long-term impacts of local flavor bans on youth tobacco and nicotine use in California.

The takeaway

This study provides important evidence that local policies to restrict the sale of flavored tobacco products can be an effective public health strategy to curb the youth vaping epidemic, without the unintended consequence of driving young people to more harmful cigarette smoking.
