Only if you want to quit. I made the decision to quit for real, for good- knowing it would be incredibly hard after 40+ years of smoking, and quitting a few other times. I only vaped originally only to get me through the hard part. But since I always loved smoking, but hated being a smoker, I found I really enjoyed vaping, and wasn't too worried about continuing it.
It was still hard the first couple of weeks, but within a month or so, I was craving a vape, rather than a cigarette. Vaping didn't completely satisfy at first, but I was committed. I no longer really needed them, but just tried a cig out of curiosity at the 3 month anniversary. It wasn't terrible, but it did have a certain nastiness in the mouth and lungs that vaping doesn't cause. It also gave me a headache. I could almost feel those 4,000 noxious carcinogens in my body again.
I'm 6 months in now, enjoying vaping, even as a hobby. No way I'll ever be a smoker again...at least as long as I can vape. With the quality of juice and equipment these days, using vaping to quit is almost like cheating - you don't really give up anything good. You still have kind of the same habit, but you can vape indoors most places, no coughing, no lingering smoke stink, breathe much better, sex is better, smell things much better- tons of advantages, but you still get to do essentially what you were doing before, with much lower health risk. It's kind of great.
