I was a smoker for over 20 yrs. I had tried everything to stop. Medication, lozenges, patches, u name it I tried it. I kept going back to smoking until four yrs ago I saw they had come out with e-cigs. I researched them for a year before purchasing one online and finally asked for one for a bday present. I quit!! I never picked up another regular cigarette again! I was short of air when I smoked and had a horrible smokers cough. All of that has been gone for years now! I’m a nurse and take care of so many patients with emphysema and copd and its so sad. The last time I was checked at the dr they said I had the lungs of a 30 yr old! I’m 46 and I use an ecig (mod) with a dripper tank and 18 mg nic all day every day. Please! Don’t take these things so many of us use to stay off of cigs away. I know if I can’t use my ecig I will be right back on cigarettes again and that’s a devastating thought.
