chewing mastic gum to counteract the acid-related mucosal irritation you can get in your esophagus and gut from slamming coffees on an empty stomach or ripping snus/zyns all day is a pretty genius move to offset any bad parts from your daily enjoyments (you deserve them)
mastic gum is not an end all, cure all - but it'll work in your favor in certain aspects (beyond all of the other things i talked about in the quoted post, which are also pretty incredible)
i'm a fan. 30+ mins daily of chewing and i haven't had bad breath since.
