It appeared that their NRT control group had used different types of NRT's. They mentioned patches and from the video it looked like some also used nicotine inhalers. While the success rate over the 4 week period was very good (7 out of 8 people was able to quit), from what I understand over the long term NRT's aren't as successful. I've seen studies that shows after 24 weeks, less than 10 percent of users who quit using patches were able to stay off cigarettes.
Yes, the test period was indeed too short to provide any solid conclusions, and as I've said, vaping is a lot more satisfying than slapping on a patch or taking a pill. vaping encompasses everything about the smoking habit that the other methods do not, with the exception of the thousands of toxic chemicals BT puts in their cigarettes, and the combustion of course, and that makes all the difference.
I've been off the cigs for 3 years now because I started vaping, and once I had a vape that lasted all day I never had another smoke.
