I use nasal snuff, the least damaging and least intrusive form of tobacco use.
I vaped pretty hardcore for 3 or 4 years, it definitely has an effect on your lungs, especially if you're into dual-coil sub-ohm builds and all that jazz.
Nasal snuff has been a God-send and is much more enjoyable, at least to me. I still smoke a nice briar pipe with a few different pipe tobacco blends on occasion, but nasal snuff has definitely curbed my tobacco/nicotine usage.
I could never go back to cigarettes and dip is just kind of gross, although I think it's better than cigarettes.
