How vaping works
As tobacco burns, smoke is produced and contains small amounts of nicotine. By inhaling the smoke, nicotine is rapidly absorbed into the bloodstream. You can tell how fast the reaction is from the instant satisfaction that smoking provides.
The problem is that along with nicotine you get 4000+ unwanted chemicals including Benzene, Pesticides, Formaldehyde, Arsenic, Cadmium, Ammonia, Carbon Monoxide and, Hydrogen Cyanide. It is the slow burning of organic material that gives off tar. By switching from combustion to vaporization you eliminate the tar. Tar sticks to your lungs and slowly releases cancer causing carcinogens. Vaping E-Cigs have actually proven to speed up the cleaning of a smokers lungs faster than quitting with any other types of quit smoking systems.
When you inhale vapor from your e-cigarette it creates a water vapor that replicates the feel and look of smoke. This means a vast majority of toxic chemicals from smoke have been removed. Not to mention all the treat flavors available other than your regular tobacco flavors, seen all the flavors are made using food extracts!
You get a similar sensation because many physical aspects of smoking remain. E-cigarettes provide a viable and satisfying alternative to traditional smoking.
