thanks for your interest, Ill ask the guy who invented it. I think it reduces the risk of negative effects to lung tissue from high temperatures. I dont know what the threshold temperature is to prevent damage/irritation from heat, or the severity of damage/irritation from simply smoking. With things that are inherently bad for you the only thing you can really do is increase the margins of safety. Also prophylactics are definitely in the safety category. let me know if you find anything on the effects of temperature on the lungs.
