oh dang would have been cool if there was a mod already, i got this mod http://www.nexusmods.com/fallout4/mods/13431/?, lets you smoke cigars and cigarettes but its a standing still animation only dang thats pretty awesome, thanks for the mod links, i was kinda hoping to continue to learn how to just make my own mod but still thank you very much man, u r da best :3 Basically, for making your own, you're going to have to take the cigarette .nif and turn it into a properly positioned head piece that goes in the correct item slot (since I'm assuming you'd want to to be able to be worn with helmets). There's several ways you can do this via nifskope, 3ds max, or even with body slide's tools. The easiest way without having to learn a new piece of software like 3ds max would be to create a mashup. Here's a little noob friendly tutorial on how to do that and what tools you'll need. And don't worry about it already being done. If it's what you want to make, do it. It's a way to learn! http://arideya.tumblr.com/post/139307195693/arideyas-guide-to-modding-fo4-outfits-outfit
