Long answer:
I was down to about 4 cigs a day with my e-cig, then I got the passthrough in the mail and stopped smoking that day. The passthrough allows you to vape at the computer, the TV, and in the car without fiddling with the batteries. Over the course of the last 18 or so days of quitting I did smoke about 5.5 analogs which were left in the last pack I had. They tasted real bad compared to the lovely flavors in the e-cigs. I have really gotten into making my own flavors. I mostly like VG, and only use PG if it is in a pre-mixed flavor that I have around.
As far as I am concerned, I am quit. Been trying for about 8 years now, so that is an accomplishment. Now if I start lowering the nic levels I could eventually get down to zero nic, and then decide whether to keep vaping or not.
I love the fact that I can vape anywhere, doesn't smell up the house or clothes, doesn't upset many people, and doesn't turn my teeth brown.
Right now I am vaping an "off" flavor I made that is not quite ready for prime time. It is champagne, pear, peach, and cinnamon. Pretty good, but I've had better.
I hope your husband will try it. If he doesn't like the tobacco flavors right off, cappuccino, is real good and surprisingly like tobacco in many ways. And I always add tobacco to the peach, my favorite.
So the short answer to your question is: YES.
