Fun idea.. But insanely dangerous the threat of detection from players/zombies would double smoking at night would be damn near suicidal even in day time people would spot puffs coming from even the thickest foliage plus you'd reek of tobacco possibly luring the curious zombie It'd be nice if you could either consume the whole pack like food for instant benefit or equip them as a tool for a longer passive buff I cant really think of any survival benefits these would have.. a realistic approach to these just wouldn't be fun or useful and no, you won't look cool, you'll look dead.
