I vape for the flavors, and I chase clouds. I use zero nicotine juice.
I don't need to vape, but I do enjoy it.
Different strokes for different folks, I guess. I personally don't see an attraction to vaping, but if you enjoy it and find pleasure in it for the different flavours then that's fine.
I know some people who use[d] it as a cigarette replacement and need it [or a smoke] for the nicotine buzz, but when the vaping wasn't giving them enough of a hit they went straight back to the smokes. I was fortunate in that I wasn't plagued by uncontrollable cravings the last time.... which fortunately was successful. I tried and failed many times before that, though, so I know only too well how hard it is to quit.
