My history in brief, then you can decide for yourself.
Before I start, I've lost some of the links to evidence, some is here if you look, and some is still ongoing research, I'll share what I know I can.
Was smoking for about 36 years, so at the time of taking up vaping my lungs where as good as anyone else's who smoked for that long.
Did 5 weeks dual fuelling while making the switch. Been tobacco free now for 8 weeks and 12 days.
On the 12th March 2014 I took part in a study at one of the London colleges. That consisted of an in depth questionnaire and some toxicology tests. urine, breath samples and stuff. Pictures where also taken of the e-cig brand used, I took a vtr and ego with appropriate tanks for max effect.
As the study is still in progress I haven't any official data yet, but my name is on the list for a copy if and when available.
What I can tell you, that may or may not help you decide for yourself is. And I'm going to use the carbon monoxide test results as used by smoking cessation services.
A smoker 17 ppm exhaled breath
typical NRT user 8 ppm exhaled breath
non- smoker 2 ppm exhaled breath
ppm = parts per million
I did this test twice, and both times my count was 2ppm. Which puts me firmly in the non-smoker category. Despite having smoked for 36 years, and vaping my socks off before going in.
Whilst I have not given any links to any supporting data. A copy of the counter signed "informed consent form" and "participant information sheet" for the study are in my possession. And is available for viewing in person only.
