Do Electronic Cigarettes Create Chemical Change?

Combustion such as a burning cigarette, causes a chemical change. This means that although you start with tobacco, you end up with 4000+ chemicals due to the process of combustion.

The definition of chemical change from

Chemical changes take place on the molecular level. A chemical change produces a new substance. Examples of chemical changes include combustion (burning), cooking an egg, rusting of an iron pan, and mixing hydrochloric acid and sodium hydroxide to make salt and water.

Electronic cigarettes don’t use combustion, they use vaporization which is the same as evaporation. Based on this, electronic cigarettes undergo a physical change, not a chemical change. Here is the definition of a physical change from

Physical changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (melting, freezing, vaporization, condensation, sublimation) are physical changes. Examples of physical changes include crushing a can, melting an ice cube, and breaking a bottle.

So, based on this, the vapor from an electric cigarette is composed on what is found in the e-liquid. So what is in the e-liquid? Although exact formulations differ from manufacturer to manufacturer, the typical ingredients include: propylene glycol (PG), glycerin, water, flavorings, and sometimes nicotine. The vast majority of any e-liquid is comprised of propylene glycol and/or glycerin, as these are the substances that have the low vaporization point, making it possible to create the vapor in the first place. Any reputable manufacturer should be using food grade or pharmaceutical grade PG or glycerin. Next is water, then flavoring and nicotine.


The flavorings in electronic cigarettes generally contain very small amounts of natural food flavorings such as citric acid and vinegar as well as artificial food flavorings.


Inhaling Nicotine Shows No Signs of Leading to Cancer. Nicotine is often found in tobacco cigarettes, as well as a variety of FDA approved smoking cessation products such as inhalers, gums, patches, and lozenges.

Benefits of the E-cig:

  • In practice, you can smoke an electronic cigarette as long or as short as you want.
  • Smoking at certain places is banned because of mainly two reasons, open flame and second hand smoke. The smokefree e cig does not need flame to start and secondly, all it produces is pure harmless water vapour that makes it usable at places like cinema halls, offices and another such places. Although, the product does not defy any of the rules and regulations that concerns smoking but still one must see to it that it does not disturb the environment around. The Smokefree e-cig produce is a harmless vapour which is odor that gets dissolved in air within fraction of seconds.
  • A traditional cigarette burns on tobacco that releases around 4000 harmful elements and among those 60 are identified as major cancer causing agents and many are suspected for the same. Since electronic cigarette does not burn on tobacco which is responsible for such health hazards and hence its harmless. According to a recent study of Boston University, smoking an ecig can not only be harmless but can also help a smoker to quit smoking permanently.
  • Unlike traditional cigarette that burns on tobacco and along with that harmful smoke it also leaves behind tar and other such harmful elements as byproducts of nicotine. An e-cigarette does not burn on tobacco and delivers nicotine with pure harmless vapour as by product that too under various nicotine dosages of both light and regular cigarettes.
