Thanks for my first real laugh of the day - these so-called "studies" are just the pits! When did e-cigs become aids to quitting nicotine? For some people this has actually happened,but not in many cases; we mostly want an option that works and to me it's blindingly obvious that the drug giants don't have it. Have given up "cold turkey" twice over the years, first time lasted 2 years, second 18 months. Have also done patches and cig replicas to no avail at all. As for airways, if I had always been a non-smoker I'm sure an e cig would have me coughing my guts up, but why would I need one?
I stand in wonderment as they blow smoke up the fundament!!!
