'breathing' smoke?

I'm not even close to testing this idea out, but here it goes. I'm about to have a head made of a character who breathes smoke. Whether he's talking or just breathing normally, smoke pours out of him. Is there any practical way to have this happen in suit (smoking cigs isn't a choice!)? I see there are mini fog makers you can even make on your on, like so. Would it be possible to stick this somewhere in the head, like in the muzzle and point the hose out the mouth?

Or is this simply impossible?
