I smoked tobacco cigarettes for over 20 years. I have tried gum, patches, losanges, zyban and chantix to quit smoking. In 2009 I found out about joyetech ego-t and gave them a try to quit smoking. I have found that by quiting tabacco cigarettes using ego’s that I no longer get Bronchitis which I would get two or more times a year ever since I started using tobacco cigarettes. I have not had Bronchitis even once since I started vaping.
