I was a smoker of 20 a day for 55years, had many an attempt to quit, using NRT but it never worked for more than a few weeks, I first came across e-cigs when I saw a look alike on e-bay, decided it was worth a try, very wimpy but it worked, a bit more research and I found the Ego, and since then moved onto bigger mods, but from that first e-cig I have not smoked tobacco at all,
It has now been almost 3 years Tobacco free. My health has improved and now at 70, I am as good as I was at 40.
The e-cig is the top product of the Century, and can save many lives if it is left as it is.
