This is going by the old "Fool me once shame on you, falsely convince me that tobacco products pose no health risks twice shame on me" - I think that's how that quote goes.
I'm not claiming e-cigs are _good_ for you, but greater harm than, say, soda and junk food, has not been proven.
The UK government claims they are 95% less harmful than cigarettes: https://www.independent.co.uk/news/health/vaping-quit-smokin...
Besides nicotine, e-cigarettes can contain harmful and potentially harmful ingredients, including:
>ultrafine particles that can be inhaled deep into the lungs
>flavorants such as diacetyl, a chemical linked to serious lung disease
>volatile organic compounds
>heavy metals, such as nickel, tin, and lead"
UK government claims ecigs are far, far less harmful than tobacco cigarettes.
"Research estimates that, while not risk-free..."
Less harmful but harmful nonetheless. Not without risk. Contaminants and other unnatural elements are introduced into the lungs.
Vaping is harmful, too.
Best advice. Don't be stupid. Don't smoke anything at all. It's unnatural. Your lungs are trying to tell you something when you first try it. Listen to them.
Where's the proof that e-cigarettes are harmful?
We have mountains of evidence that cigarettes are one of the most harmful habits one can do.
Do we have proof e-cigs cause lung cancer, or other types of cancer? COPD? asthma? no, we do not.
edit: people seem to be very downvote-happy on this site when they disagree with something.
Combustion of tobacco produces polycyclic aromatic hydrocarbons (PAH) which are heavily carcinogenic. Vaporization of nicotine does NOT produce these compounds.
Additionally the UK Government claims that e-cigarettes are 95% less harmful than tobacco cigarettes, suggesting they are less damaging than junk food, soda, or car exhaust. Why not ban coca-cola and real cigarettes besides ecig?
