After smoking a pack a day for 50 years I bought a starter ecig kit on a whim. I had exhausted all methods of quitting including NRT’s and cold turkey. I stopped using tobacco in 1 day…1 day! And I haven’t looked back since. While on a medical checkup last week my doctor told me that I was right in line with other ecig users in his practice. He remarked that he is extremely impressed by better health and clear lungs achieved by his patients that had switched to ecigs from smoking. He added that in many of the cases, including mine, the patient lungs were so clear that he would not be able to tell that I had smoked at all.
