A UT Southwestern study reveals a dramatic shift in U.S. public perception: 30% of adults now incorrectly believe e-cigarettes are more harmful than conventional cigarettes, up from 3% in 2012. This "perception gap" hinders smoking cessation efforts, as clinicians widely consider vaping a less hazardous alternative for adult smokers seeking to quit.
The Perception Gap: Analyzing 10 Years of HINTS Data
Researchers at the UT Southwestern Medical Center analyzed data from the Health Information National Trends Survey (HINTS) spanning 2012 to 2022. The findings, published in Nicotine and Tobacco Research, highlight a troubling trend: while the CDC reports that adult smoking has dropped to 12% in 2025, the public's understanding of harm reduction has regressed. In 2012, 51% of respondents correctly identified e-cigarettes as less harmful than combustible tobacco; by 2022, that figure plummeted to just 17%.
David Gerber, M.D., Professor of Internal Medicine and in the Peter O’Donnell Jr. School of Public Health, emphasizes that this shift has tangible public health ramifications. When smokers believe vapes are equally or more dangerous than cigarettes, they are significantly less likely to utilize them as cessation tools. This skepticism often leads to "dual use" or, more concerningly, a complete return to combustible tobacco, which remains the leading cause of preventable death in the U.S.
EVALI and "The Real Cost": The Catalysts of Misinformation
The study identifies two pivotal events that skewed public belief: the FDA’s 2018 "The Real Cost" youth-centric anti-smoking campaign and the 2019 EVALI (e-cigarette or vaping product use-associated lung injury) outbreak. Although EVALI was primarily linked to illicit THC cartridges containing vitamin E acetate, the resulting media firestorm created a lasting "halo effect" of perceived danger around all nicotine vaping products.
Cristina Thomas, M.D., Assistant Professor of Dermatology and Internal Medicine, notes that while e-cigarettes are not harmless—containing addictive nicotine and various toxicants—they lack the combustion products (tar and carbon monoxide) that drive cardiovascular and pulmonary disease. The current challenge for tobacco control strategies is striking a balance: discouraging youth uptake without alienating millions of adult smokers who require accurate risk-relative information to quit successfully.
| Public Perception Metric | 2012 Data | 2022 Data | Net Change |
|---|---|---|---|
| Viewed as "More Harmful" than Cigs | 3% | 30% | +900% Increase |
| Viewed as "Less Harmful" than Cigs | 51% | 17% | -66% Decrease |
| U.S. Adult Vaping Prevalence (2025) | N/A | 7% | Steady Growth |
| U.S. Adult Smoking Prevalence (2025) | N/A | 12% | Historical Low |
Implications for Future Cessation Strategies
Industry skepticism remains high regarding the FDA's ability to correct these misperceptions. Current research at the Harold C. Simmons Comprehensive Cancer Center indicates that e-cigarettes, when combined with behavioral therapy, offer higher success rates for quitting than traditional nicotine replacement therapies (NRT) like patches or gum. However, if the "Real Cost" of misinformation continues to rise, the U.S. may see a stagnation in the decline of smoking-related mortality. Future UTSW research will focus on whether these negative perceptions directly correlate with a measurable increase in relapse to combustible cigarettes among former vapers.
