IMO, thick white nasty smoke is from poor/incomplete combustion, usually because the fire is being starved for air, but using green or wet (soaked) wood can also be a significant contributor. Speaking from the perspective of a stickburner, you can't avoid some white smoke when adding fuel, but if you are running a hot fire there really is no reason for more than 5-10 minutes of that followed by 1-2 hours of clean, thin blue. Somebody that uses a charcoal cooker needs to weigh in, but if it's belching thick white nasty stuff for more than a few minutes, then the fire needs more air. Oh, yea, if you cram your firebox full of fuel then you are never going to get a clean burn. When I say adding fuel I mean 1-2 splits on a hot coal bed.
