Both VAPE and cigarettes contain chemical substances, but the types and amounts of chemical substances they contain are different.
Cigarette smoke contains about 4,000 chemical substances, many of which are toxic substances, such as nicotine, tar, carbon monoxide, etc.
VAPE uses a heated guide wire to heat and atomize the e-liquid in the e-cigarette into vapor for inhalation, so it does not produce combustion products such as tar and carbon monoxide.
In addition to nicotine, the main ingredients of VAPE also include additives such as propylene glycol, glycerin, and flavors. Among them, propylene glycol is irritating to a certain extent. Excessive inhalation will affect the respiratory system and cause airway inflammation. At the same time, propylene glycol will decompose to produce formaldehyde after being heated. Experiments show that the formaldehyde content produced in electronic cigarettes is 5 to 15 times that of ordinary cigarettes.
