Vaping is not smoking. Contrary to cigarettes, vaping involves no combustion. Cigarette smoke contains nearly 4,000 substances classified as toxic, carcinogenic or even radioactive (for example, polonium). The harmful effects of this smoke on health have been confirmed for many years, and are attested to in many scientific publications. In France alone, each year, cigarettes are responsible for the deaths of at least 80,000 people. 99% of the toxic molecules present in the smoke are absent from e-cig vapour.
