I see that it sounds like the smokeless ashtray, which I hadn’t really heard of before today.
This thing I’m describing was designed to be held in your hand while you smoked. The cigarette was put into a cigarette-sized hole, and only the filter stuck out. You held the whole device up to your face to smoke from the filter sticking out. The only smoke produced was expired by the smoker.
“The only smoke produced was expired by the smoker.”
I think that’s mostly what smokes up the room anyway.
