Mean hemoglobin levels and carboxyhemoglobin levels increased progressively with the number of cigarettes consumed per day. Cigarette smoking seems to cause a generalized upward shift of the hemoglobin distribution curve, which reduces the utility of hemoglobin level to detect anemia.

Men smoking more than ten cigarettes/day had a 1.4% increase in haemoglobin compared to non-smokers, whereas the increase in women was on the average 3.5% (2.7%, 3.8%, 4.7%, and 2.7% in 30-, 40-, 50-, and 60 year-old women, respectively).

Can smoking cause low oxygen levels in blood?

Effect on lungs

Smoking decreases your lung capacity, which can cause a smaller volume of oxygen to reach the bloodstream, resulting in less oxygen getting to the blood.

How can I decrease my hemoglobin?

What are the symptoms of high hemoglobin?

Why is my haemoglobin high?

A high hemoglobin count occurs most commonly when your body requires an increased oxygen-carrying capacity, usually because: You smoke. You live at a high altitude and your red blood cell production naturally increases to compensate for the lower oxygen supply there.
