Many people believe that e-cigarettes do less harm to the body. As a result, smokers who want to quit smoking but can't give up will use e-cigarettes as well as traditional cigarettes.
Sounds like a good idea? Maybe not. A new study shows that the combination of e-cigarettes and smoking increases the risk of dyspnea and coughing.
"To help people quit smoking, FDA approved drugs, such as nicotine patches or varenicline, are the first choice," said study author Dr. Krishna Reddy He is a research fellow at the Department of lung and critical care medicine and the center for tobacco research and treatment at Massachusetts General Hospital in Boston.
On the other hand, "people who smoke e-cigarettes in order to quit smoking should be warned not to use e-cigarettes and e-cigarettes at the same time. They should completely switch from smoking to e-cigarettes, and the ultimate goal is to stop smoking e-cigarettes as well."
In the study, researchers analyzed data from nearly 21000 Americans aged 12 and older. These people took part in a national survey, and at the time of the first survey between 2015 and 2016, they had no respiratory symptoms.
After another year of investigation, nearly 11% of the people who did not use e-cigarettes or tobacco cigarettes developed respiratory symptoms, while nearly 12% of the people who used e-cigarettes developed symptoms, 17% used traditional tobacco, and nearly 20% mixed e-cigarettes and tobacco cigarettes.
The researchers found that dual users were nearly twice as likely to have respiratory symptoms as pure e-cigarette users and a little more than 1.2 times as likely as pure tobacco smokers.
In addition, according to the study recently published in the American Journal of respiratory and critical care medicine, the risk of developing new respiratory symptoms in e-cigarette users is not significantly higher than that in non-smokers or non-smokers.
Dr Nancy rigotti, senior author of the study and director of the center for tobacco research and treatment, said: "this study helps determine how best to use e-cigarettes to reduce the harm of smoking." The use of e-cigarettes alone does not increase the risk of new respiratory symptoms, while the use of both products (e-cigarettes and cigarettes) increases the risk. "
Finally, smoking is harmful to health - instead of worrying about how harmful e-cigarettes are, it's better to give up smoking.
