The liquid which electronic cigarettes vaporize to create the smoke found in a traditional cigarette is called E-Liquid. Large varieties of E-Liquids are found. They are available in variety of different flavours and the content of nicotine in them varies too.

 
Since it is different from conventional cigarettes, there are certain steps you need to follow in order to get the best of the E-liquids.

STEPS TO USE E-LIQUIDS
>One of the primary ingredients of E-Liquid is vegetable glycerin. These are heavy objects and gets settle at the bottom. So, before you open the bottle, make sure to shake in properly, so that they do not remain at the bottom.
>In the next step, you need to remove the cap and add twenty drops of atomizer, make sure you count the drops. This is the part of the E-Cigarettes, which is disposable. 
>After adding the liquid, allow the atomizer to set for a few minutes. Ideally you allow it to set for at least three to four minutes. This is important, as the liquid should be allowed to saturate the internal fibers. 

>After performing the previous step, your E-Cigarette is ready. Now all you need to do is to turn on the button of your E-Cigarette, and smoke to your heart’s content.

INGRADIENTS OF E-LIQUID AND HOW SAFE ARE THEY

Many people are of the opinion that E-cigarettes are much safer than real cigarettes. Apparently, it might seem that E-Cigarettes are safer, but this is not the real story. Perhaps, the due to the fact that the flavors used in E-Cigarette are tested before they are sold in the market, has helped create such a notion. Let me site an example form you. Not too long ago, it was found that most of the E-Liquids contained a material called Diacetyl. It has been approved as a safe thing to consume. However, if inhaled in huge quantity, it might lead to serious lung damage. This is the reason, why most of the E-Liquids manufacturers have reduced and some have totally stopped using Diacetyl in their E-Liquids.

 
Real tobacco extracts are used in some E-Liquids. Tobacco is a substance that tastes bitter. If added to E-Liquids, it will add to the complexities of the E-Liquid However, it is yet to be found out, whether adding real tobacco to E-liquids makes it more dangerous.

Some of the liquids used in e-cigarettes contain real tobacco. “Tobacco absolute” is an extract of real tobacco, which is used in these liquids. Tobacco absolute is an uncontaminated, heavy extract of real tobacco, and it is bitter in taste. It adds to the complications and gravity of an e-liquid to a huge extent. It is yet to be found out, if addition of “Tobacco absolute” makes e-liquids more deadly and toxic.

WHAT MAKES E-LIQUID LESS TOXIC

As mentioned earlier, this is a concept which has developed among the smokers. However, there is no scientific proof to it. In fact, some researchers have claimed, that E-Liquids are no less toxic than real tobacco. Given the fact, that many chemicals are mixed to manufacture E-Liquids, might make it even more harmful than real tobacco.
