Smoking is associated with a large number of lung disease risks in healthy non-smokers



A new study from Boston University School of Medicine shows that healthy non-smokers who smoke for a long time may suffer from lung diseases ranging from asthma to COPD. The researchers assessed the potential smoking risks of healthy people and adjusted other potential risk factors, such as past smoking and smoking, and secondhand smoke exposure.

It is proposed that nebulization is a safer alternative to cigarettes, but public health experts have been encouraging people to change their views: nebulization is possible Less harmful That smokes. However, more and more studies have linked nebulization to potential health problems, including everything from gum inflammation to wheezing.

The researchers behind the latest study pointed out that many previous studies on the potential health risks of vaping have focused on cells and animal models. In the case of human subjects, these studies are usually brief in nature and focus on acute rather than chronic diseases.

The potential problem with assessing the risk of vaping is that many vape people first start using cigarettes and then transition to e-cigarettes. In some cases, this transition is stimulated by the development of smoking-related health problems (such as lung disease). What about healthy people who have never used tobacco?

The new study extracted data on more than 21

,000 healthy adults from the “Tobacco and Healthy Population Assessment” (PATH). Only healthy participants who have not reported any lung health problems are included. In addition, the research also adjusted for factors such as cannabis and tobacco use, past and current exposure to second-hand smoke.

It was found that current e-cigarette users face a 43% surge in the risk of respiratory diseases, while former smokers face a 21% increase. When looking at specific diseases, nebulization represents a 69% increase in emphysema risk, a 57% increase in COPD risk, a 33% increase in chronic bronchitis risk, and a 31% increase in asthma risk.

Xie Wubin, the lead author of the study, explained:

Through a longitudinal study design and extensive sensitivity analysis, the study adds more and more evidence that the use of e-cigarettes has long-term health risks to the respiratory system.
