Use of a smokeless tobacco product called snus is correlated with asthma and other problems, according to research reported by Reuters.
All in all, participants who reported having any respiratory symptoms were more likely to be smokers and dual users of cigarettes and snus. However, snus users were more likely to suffer from wheezing and night-time chest tightness, chronic bronchitis, and chronic nose and sinus problems, when compared with participants who were completely tobacco-free.
The study team also found that people who reported having asthma were more likely to be current snus users and the same link wasn’t seen among past snus users, dual users or people who only smoked.
“My guess is that the finding between a higher risk of asthma in snus users is related to inflammation in the upper part of the airways. This inflammation can then expand to the lower parts of the airways and thereby cause asthma,” Janson said.
