The FDA's ban on flavored e-cigarettes has not caused adults to quit vaping, and may have prompted some to return to regular cigarettes.
On February 6, 2020, the U.S. Food and Drug Administration banned the sale of e-cigarettes in multiple flavors, with some important exceptions.
The researchers point to policy loopholes as the main reason why policies fail to motivate people to quit smoking.
Fewer than 5 percent of the 3,500 adult e-cigarette users surveyed had given up vaping because of the flavored e-cigarette ban, according to findings published in the journal Tobacco Control. The remaining respondents switched to other forms or flavors of e-cigarettes or other types of tobacco products not covered by the ban.
"A growing body of literature shows that the flavors of e-cigarettes themselves cause harm when inhaled, so banning flavors makes sense," said Tobacco Research Specialist, Professor of Health and Preventive Public Health Sciences and Community Center at the University of Rochester Medical Center. Deborah J. Ossip said. "But the ban doesn't seem to be working. People - including young people - still have access to flavored products and are still using them."
According to lead author Dongmei Li, associate professor of clinical and translational research, of obstetrics and gynecology and of public health sciences, a big part of the problem is that the ban doesn't cover newer products, such as disposable e-cigarettes.
“Other forms of flavored e-cigarettes, especially disposable e-cigarettes, became very popular after the FDA policy,” Lee said. “FDA policy also does not ban mint or tobacco flavored products – our research shows that many people switched to mint flavored e-cigarettes after the ban. Many people seem to find menthol a nice flavor.”
According to the study, nearly 30 percent of survey respondents switched to canister or disposable flavored e-cigarettes, and another 30 percent switched to mint or tobacco flavored pods. Some reported switching to traditional tobacco products: 14% switched to combustible products, such as cigarettes, and 5% switched to smokeless tobacco (i.e. chewing or dipping). Less than 5% of respondents stopped vaping after the FDA ban.
Using statistical models, the researchers looked for factors associated with these changes in e-cigarette use behavior. Using fuel tank system e-cigarettes and disagreeing with the FDA flavor enforcement policy was strongly associated with switching to other flavored e-cigarettes.
Using mint-flavored e-cigarettes in the past 30 days was associated with switching to mint-flavored e-cigarettes. People who reported smoking on a daily or several days were more likely to switch to tobacco-flavored e-cigarettes or combustible tobacco products.
On the other hand, people who used flavored e-cigarettes without nicotine were more likely to quit. Although the study was not designed to show cause and effect, the association supports previous research showing that reducing nicotine levels in cigarettes can help smokers quit. However, further research is needed to better understand the relationship between low-nicotine e-cigarette use and smoking cessation.
Looking ahead, Lee believes the policy could be effective if it covers all flavors of e-cigarettes, including menthol flavors and all types of e-cigarettes, and if there is active monitoring of policy implementation and compliance.
"Both are important to help reduce the epidemic of vaping among young people in the United States," she said.
