I've often wondered about this buzz that many people refer to on here. I have felt a buzz or dizzy feeling when I've been deprived of nicotine for say... I dunno 6 hours or more. I consider it more of a rush. I've never experienced a buzz beyond that.
I do find that vaping for me is far more relaxing than analogs. I enjoy taking it slow, nice and easy, where as analogs are "timed" so I would try to get the most of my smoke for my money. With vaping I can relax and take it in when I want.
So yeah, though I don't seem to experience the same buzz as you and others have described I definitely feel a difference and prefer it.
Maybe it's the lack of the tar and other carcinogens that make the difference?
