Better to be safe than sorry. I have COPD (from different kind of smoke) so I'm getting a mask for smoking. Fighting for air really sucks and while you are younger, you may feel you are immune or maybe tough enough to handle some discomfort. But if you are exposed to prolonged smoke frequently and COPD hits you down, you'll really really wish you'd made some different choices way back when. For anyone noticing serious irritation when smoking, time to get smart!
Okay, off my soap box and back to slicing the bacon we smoked a couple days ago!
