Can ecig vaporizer pens cause pneumonia from 2nd hand smoke?

Yes, e-cigarette vapor can potentially contribute to respiratory issues, including pneumonia, particularly in individuals who are vulnerable, such as those with pre-existing lung conditions. While the risk is generally considered lower than that associated with traditional cigarette smoke, inhaling vapor can still introduce harmful substances into the lungs. Secondhand exposure to e-cigarette aerosol may lead to inflammation and respiratory complications over time. However, more research is needed to fully understand the long-term effects of e-cigarette vapor on respiratory health.
