I smoked for about 40 years. None of the quit smoking products have ever worked for me. I tried an electonic cigarette approximately 5 years ago. For about 2 to 3 weeks I used both combustible cigarettes and the electronic cigarette. I soon found myself using only electronic cigarettes and I must admit I was quite surprised.I have not smoked a combustible cigarette since that time and have reduced the nicotine level. I vape menthol e-cigarettes. My Doctors are very pleased with the health benefits I have achieved by my quitting smoking combustible cigarettes and replacing them with e-cigs. I think they have been so pleased by my success,they are encouraging other patients who smoke to try e-cigs. How I wish e-cigs had been invented a long long time ago. I would not have smoked for so long a time if they had been available years ago.
