Which is more harmful, e-cigarettes or regular cigarettes?

Electronic cigarettes are more harmful.

Electronic cigarettes are no less harmful than regular cigarettes or even more so. E-cigarettes heat a special liquid to produce a vapor that is inhaled. The liquid vapor in many e-cigarette samples contains carcinogens such as formaldehyde and acetaldehyde, with formaldehyde concentrations much higher than those of regular cigarettes.

If the resistor wire that heats the liquid overheats, it produces even higher levels of harmful substances. E-cigarettes are more harmful than regular cigarettes, and may affect immune system function, leading to a decline in immunity, especially e-cigarettes with aromatic additives are the most serious. In addition, e-cigarette users are more likely to experience cardiac arrhythmia, heart attack and sudden death.

Status quo

More than 90 percent of the world's e-cigarettes come from places such as Shenzhen, China, but there is still a gap in China's regulation of them. In China, e-cigarettes are neither medicines, nor health products, medical devices, nor tobacco, so most e-cigarettes are in a state of "three noes", i.e., no product standards, no quality control, no safety evaluation.

In the international arena, there is a big difference in the attitudes and policies of governments towards e-cigarettes. Some countries consider it a consumer product, others consider it a drug, and still others consider it a tobacco product. As a result, policies on e-cigarettes vary, with some countries supporting them, some banning them, others regulating them appropriately, and still others not taking a position until 2019.
