Yes, or made of wood but the key factor is that there's 1) a fireplace inside, 2) no chimney, so the smoke just freely rises inside and exits through a hole in the roof. You are literally being smoked inside, and you breath the smoke all the time.

I didn't live in such huts, just slept ocassionally when hiking in mountains.
