Carcinogenicity Comparison: Heated Tobacco Products vs. Cigarettes
This study, titled 'A Comparative Approach to Assessing the Carcinogenic Impact of Tobacco Products: Heated Tobacco Versus Cigarettes,' examined eight carcinogens known to be present in emissions from both heated tobacco products and cigarette smoke. Usin
The title of this study is “Method for Comparing the Carcinogenic Effects of Tobacco Products: A Study of Heated Tobacco Products vs. Cigarettes”, focusing on eight known carcinogens present in both heated tobacco products (HTPs) and tobacco smoke emissions.<\/span><\/div>

Researchers employed a risk assessment method consisting of six steps to compare the harmful health effects of the two products. “The first three steps include a dose-response analysis of cancer data, generating relative potency factors with confidence intervals. The fourth step assesses emission data to derive confidence intervals for the expected emissions of each compound. The fifth step calculates the variation in cumulative exposure (CCE) probabilities, leading to an uncertainty range for CCE. The sixth step estimates the associated health impacts by combining CCE with relevant dose-response information.”<\/span><\/div>

The aggregated data indicates that when using HTPs instead of cigarettes, the estimated CCE is 10 to 25 times lower. Researchers noted that this difference suggests a much smaller reduction in life expectancy based on the dose-response information available to smokers. However, considering that only eight carcinogens were analyzed, this is merely a preliminary conclusion.<\/span><\/div>

Additionally, a 2018 study conducted by renowned anti-smoking expert Dr. Konstantinos Farsalinos analyzed and compared the carbonyl emissions from HnB devices, e-cigarettes, and regular cigarettes.<\/span><\/div>

Compared to cigarettes, HnB devices showed a 91.6% reduction in formaldehyde, an 84.9% reduction in acetaldehyde, a 90.6% reduction in acrolein, an 89.0% reduction in propionaldehyde, and a 95.3% reduction in crotonaldehyde.<\/span><\/div>

Regarding e-cigarettes, levels of propionaldehyde and crotonaldehyde were not detected, and other carbonyl levels were very low. When using 5 grams of e-liquid, carbonyl content was reduced by 92.2% to 99.8% compared to 20 cigarettes. When comparing 20 high-quantity cigarettes to the same number of cigarettes, the measured reduction was between 81.7% and 97.9%.<\/span><\/div>
