I smoked for 40 years and tried several times to quit using gums, patches, hypnosis, and cold turkey with no success. 8/24/14 I smoked my last cigarette and after much prayer, started vaping. My brother, who also quit, had purchased the hardware a week earlier for both of us. I started using 18mg. I have not smoked any tobacco since. I currently us 6mg and have gradually reduced my compsumption. I know several others who have quit and many more who have cut down dramatically. My pulse rate dropped about 20 beats a minute, my breathing is so much better. I thank God nightly for His help and the electronic device.
