The cinnamon-vanilla flavor

According to scientists from the University of Medicine of Rochester (USA), cinnamaldehyde [ou cannelle] and vanillin [vanille] are part of most toxic flavoring chemicals on white blood cells which work for our immune defences. Other work published in 2019 in the National Library of Medicine suggests that the aroma of cinnamon can  » disrupt the immune defense system in the lungs and exacerbate the risk of getting respiratory disease « . Indeed, vaping this aroma would have a very harmful effect on the elimination of mucus and the clogging of the lungs. It should also be noted that under the effect of the heat of an e-cig, vanillin turns into benzoic acid and benzenetwo known carcinogens.

Mint flavor

In their work published in April 2023 in the journal Respiratory Research, researchers from the University of Pittsburgh (United States) explain that people who vape menthol take shallower breaths and have a lower lung function than users of non-menthol products. Moreover, according to their analyses, the mint aroma  » produces more toxic microparticles and would additionally be «  associated with poor lung function « .

The popcorn flavor

To obtain the characteristic buttery and creamy sapidity of the taste of popcorn, one generally uses diacetyl. However, when heated and inhaled, this chemical component can become harmful to health. In any case, this is the conclusion of a study published in 2017 in the National Library of Medicine where scientists from the Commonwealth University of Virginia (United States) evoke the case of “popcorn lung” (or bronchiolitis obliterans ) in North American factories where cookies and popcorn are made. Furthermore, inhaling the popcorn scent can potentially lead to malformations in the fetusespecially in the face and cleft palate.
