I tried unsuccessfully 3 times to quit smoking including cold turkey and hypnosis. Since switching to e-cigs I have not smoked or wanted to. I am so thankful for e-cigs. E-cigs have changed my life and outlook for the better. I cannot be more thrilled with my decision to stop smoking and start vaping. Extremely grateful! Moving forward I am worried about regulation and possible cost increase due to any regulation. I am also very concerned about big tobacco companies pushing out the small independent e-cig makers. My top concern about big tobacco companies taking over the e-cig market is that they will start adding other addictive and or harmful ingredients to the e-juice. If big tobacco takes over the e-cig market I will find a way to quit. I do not trust big tobacco. I hope this does not happen as I firmly believe that vaping is the answer to help people quit harmful smoking which will result in the saving of so many lives.
