Recently, a paper published in the well-known journal "Progress in the Treatment of Chronic Diseases" attracted the attention of the medical community. The article pointed out that smoking will further worsen the symptoms of patients suffering from chronic obstructive pulmonary disease (COPD). If it is impossible to quit smoking, switching to electronic cigarettes can reduce the deterioration of their symptoms by about 50%, and this health improvement can be maintained for a long time.

Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by symptoms such as cough, chest tightness, shortness of breath, and shortness of breath. If not taken seriously, the disease will further develop into pulmonary heart disease or respiratory failure, with a high disability and fatality rate.

The research was led by scholars from the Center of Excellence for Accelerating Tobacco Harm Reduction (COEHAR) at the University of Catania, Italy. The paper shows that for COPD patients, if they continue to be exposed to cigarette smoke, the chances of respiratory infections and symptoms worsening will be greatly increased, and smoking cessation is the first task to improve their symptoms. However, the reality is that most patients have difficulty quitting smoking, so switching to electronic cigarettes to reduce harm is a very practical method.

The clinical observation cycle of this study lasted 60 months, which was the longest observation cycle in the previous similar studies. Finally, 39 COPD patients provided complete data, 20 of whom were smokers and later switched to e-cigarettes. The researchers collected the relevant data of these 20 patients before switching to e-cigarettes and compared them with the follow-up data for 60 months. In order to ensure the objectivity of the study, the researchers also selected 19 patients who only used cigarettes as the control group, and conducted a comprehensive assessment of their respiratory tract deterioration, vital capacity index and quality of life.

Research data shows that in the group of e-cigarette users, 9 people successfully quit smoking after switching to e-cigarettes. Although the remaining 11 people did not completely quit smoking, their smoking rate also decreased significantly. The severity of COPD symptoms in these patients was reduced by about 50%, and there were significant continuous improvements in lung function, respiratory system health and physical activity. However, the smoker patients have not changed significantly in these aspects.

Another important finding of the study is that during the five-year study period, only 2 COPD patients in the e-cigarette group relapsed to cigarettes. The author points out that this is because e-cigarettes simulate the smoking process and related experiences, which can effectively prevent relapse, which is also an important mechanism for e-cigarettes to help long-term smoking cessation.

The report also cited data from a large study of 1190 CODP patients in the United States from 2014 to 2015. The study found that 75.7% of patients said that their respiratory symptoms had improved after switching to e-cigarettes, and many patients were using e-cigarettes. To avoid relapse.

The author emphasized in the paper that, given that many COPD patients are still unwilling to quit smoking even if they have obvious symptoms, this study is even more valuable. Doctors can suggest that these patients choose relatively harm-reducing e-cigarettes as a substitute, thereby reducing the pain of quitting smoking and illness. After all, it is scientifically proven that e-cigarettes can reduce harm by 95% compared to cigarettes.
