I think mranswerman's answer is the closest.
Haemoglobin is the component of blood which normally picks up from the lungs, and carries oxygen to tissues. The smoke from a cigarette contains gases CO, and CO2. The affinity of CO to haemoglobin is higher than O2 by several orders of magnitude. Therefore, the haemoglobin binds to the CO in preference to O2. The other factor involved is that CO2 interferes with the O2 carrying ability of haemoglobin, but in a different way.

O2 Carrying Capacity

The smoke in a cig. contains carbon monoxide. Now a red blood cell that is to carry oxygen, will bind to the carbon monoxide over two hundred times greater than O2. So when you smoke, you load up some red blood cells with CO and CO does not leave the red blood cell so a portion of your red blood cells are no longer carrying O2.

The amount of co2 in smoke, also carbon monoxide, takes the place of the oxygen that was normally in the blood. The co2 tries to actually be the oxygen, but it doesn't help the body because we don't need it. Thank you.

your blood cells carry away to the heart whatever is in the lungs , if its 70% smoke that's what the heart sends out to the body .If that's all the blood has to carry then that's all there is oxygen deprivation

do to all of the chemicals and tar especially tar that is in the cigarettes....it blocks the alveoi which are small sacs in the lungs where the switching of oxygen takes place...if those get blocked there is no way that the oxygen can get out of the lungs into the blood stream where it needs to be... some oxygen can get into the blood but not as much as what should be

It contains Carbon Monoxide which basically "pushes" Oxygen off of red blood cells.

when you smoke it effects the air supply in your lungs which therefore does not fully allow your oxygen to circulate through out your body

Well there is a diff in concentration between OC and O2.
