The first known person on record to have the idea for an electronic smoking device was Herbert A. Gilbert. In 1963, he filed a patent for this type of product, being entirely ahead of his time in more ways than one. He was well aware of the hazards of tobacco.
Liquids used in Electronic cigarettes are usually made up of four substances : Propylene glycol or vegetable glycerin (sometimes a mixture of both ) , Distilled water , flavorings and Food , depending on the decision of consumer- nicotine . In principle , except nicotine , none of the other ingredients is harmful to the human body
Electronic cigarettes epitomize everything about modern technology that is wonderful. They offer great convenience, save their users a great deal of money, and they provide the same pleasure customers are used to with traditional cigarettes - all without the burdens that come with smoke.
in my opinion it is that electric cigarettes are very harmful to the body but pollute less so it is best not to smoke to not hurt our bodies or the world we live in.
