The harris poll asked a sample of smokers, do you believe that smoking will probably shorten your life, or not? of the 1010 people in the sample, 848 said yes.

Yes it is bad in common its never ok to inhale any gas but oxygen into your lungs this is whats causing them to cough my uncle is a vapor so its water instead of smoke still its bad for u imagine that vapor going to your lungs and turning back to liquid your lungs are going to store more and more water that is why he coughs to and nicotine is also the real problem it is addictive and makes people waste money on cigarettes  

:D

The correct answer is "the protesters were attacked by chinese troops and many were killed or arrested."
