I'd say switch to snus or snuff or something to mitigate lung damage. My only vice is snus, I don't touch caff/alc/weed/etc - my anecdata as someone who spent the majority of their life highly active and a non-tobacco user is it affects my tendon healing rate negatively. For ex. when I do lots of handstands or planche work my distal biceps tendon seems to take longer to become fresh again vs. when I was not using snus. However, snus vs. caffeine my sleep is miles better and I often wake up infinitely more refreshed than I do when I used caff, so I ultimately am choosing snus for now.
