Do non-smokers smell like cigarettes if they are around smokers a lot?

yep. second hand smoke can cause the same problems that smoking causes.

yes

Yes, of course. Smoke clings on to everything--hair, clothing, etc. That's why I avoid smokers. You should really ask your friend if his parents smoke around him because smoking around a child who has bronchitis is basically abuse!

Also, secondhand smoke is more dangerous because the smoker has a filter on his/her cigarette that the person inhaling the secondhand smoke does not have. If your friend keeps breathing this cigarette smoke, it could cause very serious health problems and even death.
