I’ve seen some bad stuff from it. When I was in HS I did those Skoal bags for a couple weeks. lolI quit smoking almost 10 years ago (fuuuuuuuuuuck I got old quick).
But when I worked at a feed store, I used to chew during the day - can't smoke at a grain bin. Had to walk a block away to have a cigarette.
Also chewed for a week on Senior Trip, because I went to a private Christian school my senior year.
I smoked because it killed me on the inside.
Chaw will eat your face off before it kills you.
