Dr Sanjay Gupta reports that some of the most popular e-cigarette brands contain carcinogens, they can still cause cancer. The FDA has also detected a toxic chemical found in antifreeze in some leading brands. Although manufacturers say they are "pretty sure" their product is safe, the jury is still out about the health effects (and consequently second hand effects) with e-cigarettes. Manufacturers are NOT required to disclose the ingredients in e-cigarette liquid nor the substances present in the vapor inhaled and exhaled by the user.
Have you read the other posts in this thread? Several users of e-cigarettes report having reactions with them, so much so, some would revert back to smoking and say they should not be on the market without health warnings!
Even someone who sells them in London (the first shop to sell them in Covent Garden) says she would NEVER promote them as a healthy option. "The only good smoking is no smoking" (her quote).
Look up the following sites: "Should you worry about secondhand e-cig vapors". "A new cancer study found e-cigarettes affect cells the same as cigarettes". ROONEY - e-cigarettes carry harmful effects for smokers,non smokers". "My boss smokes e-cigarettes in the office is this safe". Just to mention a few! Not to mention Dr Stanton Glantz Director for the Center for Tobacco Control Research and Education at the University of California San Francisco who says and I quote: E-cigarettes do not just emit "harmless water vapor" Secondhand e-cigarette aerosol (incorrectly called vapor by the industry), contains nicotine, ultrafine particles and low levels of toxins that are known to cause cancer. "E cigarettes contain and emit propylene glycol, a chemical that is used as a base in e-cigarette solution, and is one of the primary components in the aerosol emitted by e-cigarettes. Short term exposure causes eye, throat and airway irritation. Long term exposure can result in children developing asthma". Further "even though propylene glycol is FDA approved for use in some products, the inhalation of vaporised nicotine in propylene glycol is not. Some studies show that heating propylene glycol changes its chemical composition, producing small amounts of propylene oxide, a known carcinogen". In fact read the whole article "Americans for Nonsmokers' Rights 2014".
Also to "ineedasuername" I smoked casually, not like an addict, in my late teens and early twenties when studying for exams, and CHOSE to stop because I could not get rid of a constant sore throat and cough! (Note- without any of the devices available today, just used my common sense really!)
As for sending out former smokers to be with smokers, then that is exactly what smokers used to do to non smokers, pollute the air, how the tide has turned! Now they now don't like the smell, should not be exposed to "harmful" smoke" etc etc. Ironic isn't it?
