What Is In Electronic Cigarettes?



Electronic cigarettes (e-cigs) are not new inventions, but many people still don’t understand how they operate. The ingredients used in making e-cigs are harmless both in their inert states and when heated. The scientific community, however, is yet to give evidence to the safety of these cigarettes.

Tobacco users wishing to smoke e-cigs should learn about these ingredients to make informed decisions on whether or not to vape (Check out to learn more about vaporization & vape temps). The ingredients include:

Propylene glycerine

Propylene glycol is used in making e-cigarette liquids, which is known as a base. All e-cigs use bases, though their exact chemical composition may differ. Propylene glycol is commonly used because it produces a vapor cloud more realistic than other bases.

This chemical compound has been proven safe for human consumption, and it is used as a major ingredient in fog machines and inhalers for asthma patients. It is used in countries all over the world.

Vegetable glycerine

Some electronic cigarette manufacturers prefer to use vegetable glycerine as a base, instead of propylene glycol. It was first introduced as an alternative to the above compound because some users complained of dry throats and mouths after using propylene glycol.

Though it produces a lot of vapor, some vapers complain that it doesn’t hit their throats as much as they should. It is also a safe substance found in many other substances commonly used in homes including flavorings, food coloring, and even some beauty products.


Nicotine may or may not be present in an e-cig. For e-cig liquids that contain nicotine, the levels vary from manufacturer to manufacturer. Vapers can easily tell how much nicotine is used in an e-cig by reading the cigarette labels. In most cases, this level is indicated as a percentage of the total volume or weight of the liquid used. It can be found in the recipe section of the label.


There are some e-cigarettes manufacturers that use normal tobacco flavors, but others do not. Some people prefer to use alternative flavors such as the ones used in candy or other snacks. Again, the use of the same flavoring in common foods implies that they are safe for human consumption. In fact, these flavorings can easily be purchased in local or online stores, meaning they are being used widely all over the world.


Vapers may have noticed that some e-cigs have thicker liquids than others. It is interesting to note that this is not a coincidence, since some people prefer it that way. Distilled water is normally used if the e-cigarette liquid is to be made less viscous or thick. The safety of water requires no explanation or discussion.

In conclusion, it is clear that electronic cigarettes are relatively harmless; even though the concrete scientific evidence for their safety is not available. What is more, the same technology used in designing and manufacturing e-cigs has been used for a long time in making other harmless products.

For example, atomizers and theatrical fog both operate on the same principle, the only difference being that these two do not have nicotine. Those who buy their e-cigs from reputable vendors have nothing to worry about with regards to their safety.
