Einfach Mal Selbst Gedacht

Dampfen ist gesünder als der Gebrauch einer Iquos oder das Rauchen 

Am 05. Januar 2020 haben die Forscher um Romain Dusautoira und Gianni Zarconea die Studie mit dem Titel: Comparison of the chemical composition of aerosols from heated tobacco products, electronic cigarettes and tobacco cigarettes and their toxic impacts on the human bronchial epithelial BEAS-2B cells veröffentlicht. In dieser Studie kamen sie zu dem Ergebnis das der Stresslevel für bronchiale Epithelzellen beim Dampfen am geringsten ist, da am wenigstens Schadstoffe ausgestossen werden. Ausnahme hier bei wären E-Zigaretten welche in einem hohen Leistungspektrum gedampft werden. Meine persönliche Vermutung ist, das es hierbei wieder bewusst oder unbewusst zu Kokelstudien kam. Es ist aber nur eine Vermutung da ich die zum Testen benutzten E-Zigaretten nicht kenne. 

4. Conclusion

Within the framework of tobacco harm reductions, in which smokers ideally should be able to freely choose from a variety of alternatives for smoking, emerging tobacco products (such as HTP) and e-cig seem to have potential of a promising new offering. However, it is fundamental for smokers to know and compare the health risks of these different emergent devices in order to determine which product should be preferred for smoking cessation. Our study provides comparative data on both chemical composition of HTP, e-cig and tobacco cigarette emissions and their toxicological impacts on human bronchial epithelial cells. We first report that HTP deliver slightly less nicotine and emit much lower amounts of carbonyl and PAH compounds than tobacco cigarette. However, HTP emissions still contain carcinogenic compounds (e.g. formaldehyde, acetaldehyde and benzo[a]pyrene) and the amounts of carbonyls and PAHs in HTP aerosols are higher than in e-cig vapours. In accordance with the levels of toxic compounds in each aerosol, HTP aerosol exhibits reduced cytotoxicity compared to cigarette smoke but higher than e-cig vapours. HTP and e-cig have the potential to increase oxidative stress and inflammatory response, in a manner very similar to that of cigarette smoke, but only after a more intensive exposure. In addition, our data support that e-cig use at higher power settings emit higher carbonyl and PAH compounds and, consequently, generate more oxidative stress. Finally, this study contributes to a better understanding of HTP and e-cig emission properties and their related toxicological impacts and provides important data needed for risk assessment purposes, by demonstrating that HTP might be less harmful than tobacco cigarette but considerably more harmful than e-cig. Further long-term studies in animal models should be conducted to confirm these in vitro findings and to allow the assessment of chronic exposures to emergent tobacco products. In addition to the toxic impacts of these products, comparison of their addictiveness is another key element to take into account in the tobacco harm-reduction strategy.
