The main difference between smoking and vaping is the product that each process creates. Smoking creates smoke, and vaping creates vapor. Smoke is a combination of gas, liquid, and solid particles released when you light a cigarette and inhale. Vapor, on the other hand, is entirely made of gas particles that come from a purified e-liquid. This liquid has none of the additional toxins found in cigarettes and other tobacco products. Also, there are no solids in the vapor you inhale, as there are in smoke. The ash and tar that cigarettes produce can get deposited in your lungs when you smoke, and they can stay there forever. There is much less risk in vaping than there is in cigarette smoking.
