Nicotine Addiction

Cigarettes may (allegedly) not kill people anymore, but it's still nicotine, right?

You can get addicted to other substances, so nicotine seems like a pretty obvious one to have in there, too. I'm not sure how much of a pain in the ass it'd be to implement, though.

Since cigarettes provide no positive stat boosts, and are purely an RP tool, this would most likely just result in no one smoking ICly.

If this kind of RP is for you, I encourage you to RP being addicted to nicotine and getting grumpy when you haven't had one for a while. Totally valid RP :)
