It is. I was a 3-4 pack per day smoker 13 months ago, got an e cig, 4 days later i littereally threw 3 packs in the trash and used the 4th as a stress ball because I was so mad at the smelly everything in my home I had to de cigarette skunk.
I have never looked back, in fact day six, I was invited to dinner with smoking friends and, they of couse did light up after the meal. I grabbed my PV and had no desire to light up, just vape. That was a shocker to me, i had tried gum, patch, inhaler, lozenges, even chantix all to no avail but in less than a week vaping cured me of even wanting to smoke.
Add to that my impressive hardware supplier that gives a LIFETIME warranty on hardware - including atomizers, chargers and bateries and a fantatic super mini that really does provide good vapor, great flavors, self cleaning, USB charging in ANY USB port, even a netbook running only on battery power, free shipping, fast shipping, live people when I call them and, what is there not to like?
No nic fits, no withdrawls, I simply didn't want cigs anymore, vaping feels and tastes better, is less expensive, healtier for me and everyone around me. Your wife will love it, and find quitting easy. You might need to try a few flavors and stregths and, for the best flavor, learn to refill with juices which taste far better than prefilled carts, but in no time the smoke will be gone.
