Newsflash for antis. If you ever feel depressed, maybe you should grab some nic gum if you can't afford a pack of menthols or regulars!
I believe it on nic helping someone out who's depressed. Nic helps ME out in keeping me think positively instead of negatively.
This is actually an old article...but it still highlights one benefit for even nonsmokers to use nic. And as the article points out, they don't even need to smoke to get that nic to help em feel betta.
