Which is more harmful, e-cigarettes or cigarettes?

E-cigarettes are more harmful than cigarettes.

Under normal conditions of use, the concentrations of certain metals and formaldehyde in some e-cigarette aerosols are equal to or higher than those in traditional cigarettes, which also include certain metal particles, such as nickel, chromium and lead, and are even higher than those in secondhand smoke produced by traditional cigarettes.

In addition, e-cigarettes produce some toxic substances that are not found in traditional cigarette smoke, such as glyoxal, which is flammable, toxic and irritating, and the vapor or mist has an irritating effect on the eyes, mucous membranes and upper respiratory tract.

The main hazards of e-cigarettes:

The PM1.0 indicator value of the aerosol generated by e-cigarettes can be 14-40 times higher than that of fresh air, and the PM2.5 value can be 6-86 times higher. In addition, the nicotine content can be much higher, 10 or even more than 100 times higher.

Also, it can be 2-8 times higher in acetaldehyde and 20% higher in formaldehyde. The content of some metals, such as nickel and chromium, is even higher than that of traditional cigarettes.

All of these can be harmful to the user's health or the health of those around the user. So, e-cigarettes, like cigarettes, have the problem of second-hand smoke and even third-hand smoke.
