Vapotage vs tabagisme

The primary difference between vaping and smoking is solely the fact that there is no combustion with vape products.

Combustion vs. Vaporization

The phenomenon of combustion is a chemical reaction of between a combustible (wood, paper, tobacco leaf…) and an oxidizer (primarily the air dioxygen)
From this reaction, a strong energy is released leading to the creation of various compounds very often toxic to humans (volatile organic compounds, carbon monoxide, etc.…).

Unlike cigarettes, the vaporization phenomenon induces a change of state. In this case, the passage of a body from a liquid state to a gaseous state.

Smoke vs. Vapour

Almost 4,000 toxic and carcinogenic, and even radioactive, substances such as polonium are found in cigarette smoke. The harmful effects of this smoke on health have been proven for many years and many scientific publications testify to it. Santé Publique France also makes certain information documents on the subject available to the general public. In France alone, cigarettes are responsible for the deaths of at least 78,000 people each year.

Drs Lion Shahab and Rosemary Leonard compare the impact of smoking to that of vaping in a short video released by Public Health England.

Already in 2015, a study published by Public Health England, a national agency dependent of the British Ministry of Health, revealed that electronic cigarettes were 95% less harmful than conventional cigarettes. This is mainly due to the fact that there is no combustion in the vape.

In addition, we now know that 99% of the toxic molecules present in the smoke of a conventional cigarette are absent in the vapour produced by an e-cigarette. The remaining percentage being at rates well below the authorized limits.
