Well, vaping is already completely different from smoking. But the sensation of suction, and then the sensation of TH... those are 2 factors that I find absolutely indispensable. Without them, I would be completely unsatisfied with vaping as a substitute for smoking. And even though I don't vape nearly as often as I did at first (so says my husband, though it's hard for me to objectively know - he says my frequency of vaping is FAR!!! less than at first or even the first 6 months), it is still very much a substitute; though it's been over 2 and a half yrs, though I've been off WTA for a year, and have been at 3mg nic for quite a few months now... if I didn't vape, or if I wasn't satisfied with my vape, I would most definitely go back to smoking, no question about it. After smoking for 3/4ths of my entire life, I'm pretty sure my emotional need for it, or something quite like it, will never leave me.
