Smoking Electronic Cigarettes (Vaping), With Moderate and High Dependence for Nicotine

Cigarette smoking is the most common form of tobacco use worldwide, but other tobacco products, such as e-cigarettes, cigars, cigarillos, roll-your-own, pipes, and various smokeless tobacco products are also damaging. Most harmful chemicals in cigarette smoke target metals or carbonyls generated by the thermal decomposition of carrier liquids such as propylene glycol, which is one of the main ingredients in the liquid used in electronic cigarettes, where it serves as both the carrier for nicotine and cannabinoids and the means of producing vapor which resemble smoke. This new tobacco product was made of milder sorts of tobacco, the smoke could be inhaled, and it was more damaging.
