First, let me say thank you to all the people who have commented before me. You have made statements based on and backed up by published research and factual statements. This allows me to simply share my story.
I'm a 60 year old woman who smoked for 38 years. I tried numerous methods of quitting to no avail. I had resigned myself to being a shameful smoker and probably dying a smoker's death until I was introduced to ecigs. My first purchase was a tobacco company manufacturer  cigalike . They tasted horrible and were too harsh. Then a friend took me to a vape shop where I could choose a flavor and nicotine strength with a device that worked . That was three years ago and I've never looked back. No cigarettes for three years! I'm down to 3mgs of nicotine and headed for zero.  For me it's the hand to mouth motion, an oral fixation that I've had since birth. It's just the way I'm wired. 
So, I'm extremely grateful to the Vape industry for creating a means and way for me to kick tobacco!
