Are nicotine-free e-cigarettes still harmful?

Are nicotine-free e-cigarettes still harmful? Cigarettes are harmful because they contain nicotine, and e-cigarettes on the market are now claiming to be a safe and harmless substitute for cigarettes, and they are becoming more and more popular among consumers. If e-cigarettes do not contain nicotine, are such e-cigarettes still harmful?

A new study by researchers at the Perelman School of Medicine at the University of Pennsylvania shows that just one e-cigarette can damage the body's blood vessels, even if the smoke is completely nicotine-free.

Under the banner of "no tar, no nicotine", electronic cigarettes claim to effectively reduce the probability of people suffering from lung cancer. In the latest study, a team from the University of California found that e-cigarette users have higher levels of adrenaline than the average person, which means these people are more likely to experience arrhythmias, heart attacks and sudden death. In addition, vaping can also lead to increased levels of oxidative stress in people, which can lead to arteriosclerosis. Both results are also common in the harm of traditional cigarettes.

According to an article published by the World Health Organization, second-hand smoke from e-cigarettes is actually not safe and is a new source of air pollution. Compared with smoke-free fresh air, second-hand aerosols can cause PM1.0 values to be 14-40 times higher, PM2.5 values to be 6-86 times higher, nicotine content to be 10-115 times higher, and formaldehyde to be 20 times higher. %, some metal content, even higher than the second-hand smoke produced by traditional cigarettes!

E-cigarettes with or without nicotine will still volatilize carcinogens and other aerosol particles that stimulate airway responses. The scientific nature and right and wrong of e-cigarette smoking cessation can only be verified in practice. Only smoking cessation is the healthiest way of life. .
