Will my furniture / home cinema equipment have smoke smell/particles on it?

[swordyahoo]

I had a few friends over last night who all smoke cigarettes, none of the smoked in the house but they do constantly have a smokey smell on themselves (like all smokers). Can this smoke smell/particles transfer to all the stuff in my living room through the air? Or would they have to touch it (like when you hug a smoker and your clothes have a smokey smell)
