I don't think that he does...and what makes me think that is during the episode "Chi of Steel" during Lois' dream, both Perry and Jimmy are actually smoking their cigars, but Dean just has it in his mouth...it didn't look like it was lit either. So I'm going to say no, he doesn't.

Lois: The message on my E-mail said 'secret shipment'. This is it! This is when it's arriving! It's probably coke!!...Or heroin!!
Clark:...Or pencil sharpeners.
