impossible to say.......I was able to stop my 2+ pack a day habit in mid-pack
and so far,I`ve talked 2 friends into the vaping scene.......
Me too, literally!
35-40 smokes a day, and the minute my x6 showed up it was game over.
I'd tried once back in 2010 (hence the date of my account creation) and again in 2011, but the tech was just too much in its infancy, everything leaked, nothing kicked me in the throat like a donkey, and I just wasn't digging it.
Now, with stuff like twists and x6's and clearomizers that dont leak, I had no more excuses not to give it another shot and I've been successful!! WOOT!
Now I have an MVP 2.0 on the way and I think I'll be totally set.
Sorry for rambling!
