Tobacco smoke is a chemical aerosol, composed of gaseous and particulate matter. It is also toxic and carcinogenic, and up to 70 carcinogens have been identified among its thousands of chemicals.
Electronic smoking devices (ESD) such as electronic nicotine delivery systems (ENDS) and heated tobacco products (HTP) also emit similar chemical aerosols. They do not emit simple water vapour.
In fact, ESDs emit many of the same toxic chemicals in tobacco smoke (as well as new ones); albeit studies seem to show a lesser concentration of these toxicants and carcinogens.
ESD proponents, including tobacco companies and their vociferous lap dogs, publicly claim that ESD use is less harmful (even "95% less harmful") than cigarette smoking, that cigarette smokers can "quit" smoking by switching to ESDs, and that smokers have a right to access these "safer" alternatives to cigarettes.
The "95% less harmful" factoid has been debunked for years, but even if it were true, is there such a thing as a "less harmful" poison or cancer? Is it okay to jump from the 5th floor rather than the 100th floor of a building?
The truth is that none of the manufacturers of these ESDs can or will claim that their products are safe or harmless, and so far, none of them have registered their products as smoking cessation devices in any country in the world. Doesn't that make you wonder why?
In its application to the US FDA, Philip Morris even gave an "important warning" - "It has not been demostrated that switching to the IQOS system reduces the risk of developing tobacco-related diseases compared to smoking cigarettes."
