Is electronic cigarette harmful to your body?

In principle, e-cigarettes can indeed avoid the harm caused by many paper cigarettes:
When in use, nicotine is atomized and absorbed without burning. Therefore, e-cigarettes do not have tar, the largest carcinogen in paper cigarettes. In addition, e-cigarettes will not produce more than 60 carcinogens in ordinary cigarettes.

Because it does not burn, there is no problem of second-hand smoke, at least the amount of second-hand smoke has been greatly reduced.

According to a survey commissioned by the Public Health Council of England, e-cigarettes are 95% less harmful than traditional paper cigarettes, the BBC reported. The report also points out that e-cigarettes help smokers quit smoking. It even suggested that the government incorporate e-cigarettes into the NHS medical security system.

E-cigarettes can use nicotine free cigarette oil or cigarette bombs, which is not only harmless to the public, but also makes people feel comfortable with the candy smell and beverage smell of cigarette oil.

But there are also some doubts in the public sphere:Vegetable glycerin is safe to apply to the body or eat into the stomach, but whether it is safe to inhale into the lungs after vaporization has not been determined. In addition, very few people have allergic reactions to propylene glycol.

Research shows that in addition to nicotine, formaldehyde and acetaldehyde, e-cigarette smoke still contains many chemical substances, such as propylene glycol, diethylene glycol, cotinine, quinone, tobacco alkaloids or other ultrafine particles and volatile organic compounds. After long-term use, it may still produce cancer or other health hazards.

As no relevant laws have been formulated to control (for example, there are no specific provisions on e-cigarettes in Beijing's smoking ban), it is impossible to determine that all cigarette oils sold on the market are safer than traditional tobacco, and may even be mixed with amphetamines and other drugs.
