I smoked for 17 years, but gave them up about 15 years ago when my wife became pregnant.  I also used smokeless tobacco for the same 17 year period, and increased my usage of it drastically after I stopped smoking. All total I used smokeless tobacco for 32 years.  Two months ago I tried an e-cig from a local convenience store and decided to give them a try.  I have not looked back since! I have upgraded my vaping equipment but I haven't had a single dip since I started vaping.
