E liquid is the fuel used for electronic cigarettes. They are liquids that contain a nicotine solution and flavoring. All e liquids have the same bases which are composed of Propylene Glycol or Vegetable Glycerin. Sometimes both are being added and the ratio for are just decided by the company. The last ingredient is the flavoring. However, even if all e-liquids have these materials as bases there are still differences and it can be seen especially in the difference between cheap e-liquid and expensive e-liquid.
Price is the first things that all consumers consider before buying anything. If you are a regular consumer of e liquids you can notice that there are e liquids which can be bought at $3 per bottle and there $30 per bottle. That is a big difference in price, considering that it just contains the same amount of e liquid. You might ask for the reason why there is such a big difference. The basic answer to that question is the materials being used. If the e liquid is on the cheap side then it is understandable that the materials used are only subpar. Subpar materials can mean being exposed to unwanted chemicals that can harm the body. However, no all cheap e liquid are that bad. There are some that are affordable and at the same time uses very safe raw materials.
Flavor is somewhat related to the materials used. The thing about e liquids is that if the raw materials used if of high quality it can really bring out the flavoring that is added. Flavorings sometimes get lost in the mixture if the raw materials for the e liquid are only subpar. And this should not happen because one of the main selling points of e liquids is the different type of flavoring that consumers can enjoy.
However, the choice of what e liquid you should buy is still up to your personal preference. Just make sure that before buying anything you have a thorough research on the product. You might be blinded by the affordable price but you can never know what effects it has on your body. There are many reviews online that you can read about many of the cheap e liquids, you can start your research there. It is better to have an extensive research now than have regrets later on.
