Is it normal to breathe smoke w/o smoking?
So sometimes when I go out camping with my family, we'll roast marshmallows at night. I like setting them on fire, blowing the fire out, and then eating the burnt marshmallows. Whenever I do this, I exhale smoke for about a minute until I eat another one. This also happens when I eat any other hot food while camping. Is that normal? I don't smoke and don't even plan to.
