According to results published in Insights into tobacco use.

“Our results suggest that the unique way vapers and hookah smokers use their devices may expose the nose and sinuses to significantly more emissions than cigarettes, which may in turn increase their risk of respiratory tract disease. superior”, Emma Karey, PhDpostdoctoral researcher in the Department of Environmental Medicine at NYU Langone Health at New York University Grossman School of Medicine, said in a related press release.

Researchers recorded mouth-only, nose-only, and mouth-and-nose smoke exhalation patterns in 341 individuals in the New York tri-state area from March 2018 to February 2019. All individuals used tobacco products, including cigarettes (n=122), e-cigarettes (n=123), or hookahs (n=96).

According to the results, 62% of e-cigarette users and 50% of hookah users demonstrated nasal exhalation practices compared to 22% of cigarette users. Those who used e-cigarettes had a higher rate of exclusive nasal exhalation compared to cigarette users (19.5% versus 4.9%). In addition, e-cigarette and hookah users practiced exclusive mouth exhalation less often than cigarette smokers (P

The type of e-cigarette device was significantly associated with the exhalation profile among vapers, the researchers wrote. Users of pod-style devices were more than twice as likely to exclusively exhale smoke through their nose than those using modular reservoir devices (26.6% vs. 11.9%).

“Because vaping and hookah devices are used differently than traditional cigarettes, we need to consider nose and lung diseases to assess their safety before judging whether one is riskier than another,” Terry Gordon, PhD, professor in the department of environmental medicine at NYU Grossman School of Medicine, said in the statement.
