I assume you don't have a large collection of smoking videos? If you did you'd know that a large proportion include the models being interviewed either by the producer or another model about their smoking history, routine etc. Specialized Videos in particular are strong on this. If you want nudity and more, then there are lots of those too, e.g. IRL Exposed, VSI Smoking Erotica.
As for new smokers, there is Lady Madonna's Chastity and others.
