How does carbon monoxide affect a smokers blood?

Well lets start with this, Carbon Monoxide hinders the ability to distribute oxygen throughout your body and in the body of someone who smokes  carbon monoxide passe will pass through the lining of the Lung into their blood, where it can attach to red blood cells.

It affects there lungs, heart and blood vessels

so i really think that most of the health care industry be doing more bad than good.
