This is bad because you're less likely to cough up stuff that shouldn't be in there, (which is pretty much anything besides clean air.)
Also, the girl who was with you who wasn't smoking? I bet you she hadn't smoked marijuana much/at all...I mean, why else wouldn't she have smoked it? That explains her lack of reaction.

Marijuana is a risk factor for lung cancer because it's smoke taken into the lungs? See below

About the girl. She wasn't smoking because she was on probation. You would think she wouldn't want to risk it for fear of being drug testing would you not? I was able to convince her that it wouldn't show up on a urine screening and whaddayaknow? I was right.
