I'd REALLY like a mod for smoking in-game. There was one in Fallout 3 I couldn't live without (ironic, since we're talking cigarettes here..). It had so that you could either smoke a cigarette, as a drug, and that had animation, but you could also just have one in your mouth, as a vanity item, so to speak.
If anyone out there knows how to fix this, I'd be forever greatful.
