How is it awful for the lungs? I'm interested. I've read that heavy use shows minor pulmonary deficiency after 10 years and medium use possibly protects against lung cancer. The tests I've read have been far from conclusive that it is awful in all circumstances and that it's worst in joints when there's no filter and physical matter enters the lungs (makes sense)
