Reasons for replacement of cigars by E-liquid in increasing in younger generation.

E-liquid is likely to be one of the first unfamiliar terms you might come across as you begin to learn about e-cigarettes and the terminology about them. You may have already guessed, e-liquid is the flavored nicotine liquid that your e-cigarette vaporizes.But the basic definition is that , e-liquids are the solution which contain mainly nicotine as its component. It also contains natural and artificial flavors and a carrier liquid that vaporizes when heat is applied. The carrier liquid plays an important role here , as without it its impossible to generate the flavor of e-liquid. There are 2 types of carrier liquid used usually in manufacturing of e Juice, they are propylene glycol and vegetable glycerin. http://www.vistavapors.com/
With the invent of eliquid , people have shifted their habit from cigar smoking to e-smoking. Most of the e-smokers start by purchasing refill cartridges pre-filled with e-liquid. By doing so they can save a lot of money, with e-cigarettes when you buy your e-liquid by the bottle.
Though E-liquid is a simple product market offers tremendous variety because little variations in those few basic ingredients can lead to huge variations in flavor, vapor production and the hit it gives to the throat.
Directions are clearly given on each and every bottle about the nicotine content. Also the flavors would be incredibly thick and far too dangerous for human consumption. The carrier are therefore used to dilute the e-solution. The two carrier used are propylene glycol and vegetable glycerin , which dilutes the solution to desirable strength. They work by vaporizing at relatively low temperatures and have relatively neutral tastes so that more stronger flavor is not felt , as it could be dangerous. E-liquid companies usually mark proplene glycol and vegetable glycerin as PG and VG respectively. Each e-liquid may have one carrier or a combination of both.
Based on the carriers used they are chosen by the people ,as PG is thinner and less likely to cause dry puffs, while VG is thicker, thus creating thicker vapor clouds. Mostly preferred carrier is PG because it reproduces flavors more accurately. But VG is too thick to work well with some e-cigarettes. It also have a sweeter taste. Therefore most of companies in the United States use a blend of the two, creating a balance and thus giving a perfect flavor.
