Yes Steve, vaping is not smoking and quitting smoking is the primary reason one sees improvement. The research showing that lung function can improve when one vapes instead of smoking is counter to some who some who might argue 'we don't know' the effects of vaping. Here is emerging evidence that, in this case, vaping is benign and vapers experience the benefits of quitting (reversing the harm from smoking). In my situation with asthma, I think that's significant.
BS from smokefree dot gov - your tax dollars at work.
E-cigs havent been shown to be effective
There havent been any scientific studies that prove e-cigs actually help people to quit smoking. There is also concern that using e-cigs may lead kids to start smoking regular cigarettes.
The bottom line is that we just dont know enough about e-cigs, so we dont recommend that you use them.
The lies (sorry I don't have time to insert the links. I'm heading out to dinner. It's my BD and I guess I should show up!!)
1. yes, there are studies that show e-cigs to be more effective than nicotine replacement therapy (NRT) like patches and gum
2. this 'concern' of leading kids to start smoking regular cigarettes has no basis in fact. Again, indications are that vaping is a means away from cigarettes and non-smoking kids are not taking up vaping at an appreciable rate (there are always a few who will experiment, we were all kids once and know that)
3. the old, tired, 'we don't know enough' line means we just didn't or won't look at at the reams of available studies because we have a position to maintain. See my sig!
