The chemicals contained in Vape liquid are propylene glycol, glycerin, flavorings, and nicotine.
Answer analysis: Vape liquid does not contain tar, carbon monoxide, nicotine, or suspended particles, and will not cause harm to the mouth, throat, or lungs.
The nicotine in the Vape liquid is used as a flavor and solvent. After the nicotine solution is inhaled, most of it is absorbed by the lungs and transmitted to the brain through the blood, thereby producing the pleasure of smoking. At the same time, when the nicotine solution evaporates, it will be expelled with the breath. Outside the body, no harmful substances will remain in the body.
