Summary
Introduction:
This text is a summary of a research study investigating the acute effects of chewing bags, e-cigarettes, and combustible cigarettes on small airway function and arterial stiffness in a head-to-head design. The study included 20 healthy occasional smokers who were randomly assigned to use one of the four products on four separate test days.
Key Points:
* The study found that all nicotine-containing products, including e-cigarettes and chewing bags, had harmful effects on blood pressure, heart rate, and arterial stiffness parameters.
* Lung function changes were not evident in the Chewing bag group, as it is not applied via the inhaled route.
* The combustible cigarette and the e-cigarettes with and without nicotine significantly increased the resistance of the small airways, while chewing bags had no effect.
* Changes in blood pressure and arterial stiffness were similar after smoking, vaping, and using chewing bags.
* The Chewing bag together with the E-Cig (+) showed the highest increase in values in almost all cardiovascular parameters.
* The Chewing bag showed no changes in values after the intervention regarding central and peripheral obstruction of the airways, unlike the inhalation devices.
* The study suggests that all nicotine-containing products might have a similar cardiovascular risk profile indicative of future development of arterial hypertension or atherosclerosis.
Main Message:
The study highlights the potential risks associated with the use of nicotine-containing products, including e-cigarettes and chewing bags. While chewing bags did not have the same harmful effects on lung function as inhalation devices, they still had harmful effects on cardiovascular parameters. The study suggests that all nicotine-containing products might have a similar cardiovascular risk profile, indicating the need for further research and regulation in this area.
