From the point of view of lung damage, which is worse for a person's lung - second hand cigarette smoke, or second hand marijuana smoke?
I have never smoked anything in my life.
Let’s say I am in Denver (where marijuana is legal).
Some people are smoking weed, while others are smoking cigarettes. I am being inundated with second hand smoke.
Which is more damaging to my lungs?
