Dr. Nollen, the lead researcher and joint project leader of the Cancer Prevention and Control Research Project at the University of Kansas Cancer Center, said: Quitting smoking is a top priority. But for those who are unwilling or unable to,
Our findings support the use of e-cigarettes as a strategy to reduce the harm of African-American and Latino smokers with significant tobacco-related health differences. "
Before reaching this conclusion, Dr. Nollen conducted a six-week trial in collaboration with California State University San Marcos and Brown University in which smokers compared the use of e-cigarettes and traditional cigarettes.
The joint team’s experiment found that smokers who switched to e-cigarettes had significantly reduced NNAL markers. NNAL is transformed when NNK is metabolized, and NNK is a specific tobacco carcinogen that can cause lung cancer.
Data show that compared with traditional tobacco smokers, e-cigarette users have reduced NNAL by 64%, carbon monoxide by 47%, and respiratory symptoms by 37%.
In the control group, there is a group of dual users who use both traditional cigarettes and e-cigarettes. When they use e-cigarettes, the above values are also significantly better than traditional smokers who only use cigarettes.
To be sure, when smoking cannot be completely quit or smokers are unwilling to quit, e-cigarettes can be a better choice than cigarettes. It is best if you can stop smoking altogether.
