I'm more ashamed of the cigs but I partake in both and haven't got sick at all. Even after wearing a mask for a while, no sickness. Never had more than a cough in my life.

I am very active though, including work, so im sure that plays a big part. Smoker, but still can run circles around friends on a hike. I dont really drink either which I have no clue if that makes any difference. No fastfood besides the rare chick fila.
