After smoking cigarettes for over 40 years, I was able to quit by trying various e-cigs and juices! My doctor had been telling me for years that I need to quit smoking ASAP. After 2 months of being cigarette free, doctor was shocked – said my lungs sounded like a non-smoker! Not only has my health improved dramatically, but blood pressure and cholesterol as well!! I have read some studies (not done in the US) on vaping that claim it is really not harmful especially when compared to cigarettes and I am proof of the health benefits! I had tried on many occasions to quit cigarettes with no luck. I tried a cigarette type mod – really did not like at all so kept smoking. I was advised by a fellow vaper to try a variable voltage battery and a tank – jackpot!! I now have three favorite juices, all 8mg nicotine, that have satisfied any cravings – one coffee blend, one mixed fruit and a coffee tobacco blend. I believe with the choice of flavors, batteries and tanks/cartos being available, anyone could stop the cigarettes and see immediate health improvement.
