I'm done with smoking and haven't had one for over two years. Before that, when I started vaping 4 years ago I dropped from 2 PAD down to about 6 cigarettes a day for two years before quitting altogether. I'll never go back to smoking at any price. If vaping were outlawed, I'd make my own juice and continue on. If the hardware wasn't available I'd have to quit or fabricate my own, but smoking will never again be a part of my life.
It's funny, yesterday I was at a beach water park and had to leave my mod in a locker for the day. I vaped when it was over but had no withdrawal other than a couple of times when I thought, "It would be nice to vape about now". Even then, I never considered going back to the locker and getting it out ( only about a hundred feet away). I had no nic fits whatsoever. I could quit vaping if it was necessary. I do it for enjoyment, not to support an addiction.
