Thats bullshit... Probably a study funded by a tobacco company...
If you poured gas in it I am sure that wouldn't be good for you either... You just have to watch what you buy...
When Tam and I quit smoking and started vaping we made our own E-juice... its a mixture of Propylene Glycol & Vegetable Glycerin and organic flavoring... (both approved by the FDA). we never even put nicotine in the stuff we made...
Helped us BOTH beat 30+ year smoking habits... Both smoke free for over a year now!
I got a buddy that still vapes HARDCORE for over 2 years... at the rate and volume that he vapes if it was worse for you than cigarettes then we would have buried his ass a LONG time ago!
