How does smoking tobacco in human lead to oxygen deficiency in their body?

tobacco releases co and this attack the haemoglobin present in our body as the haemoglobin is reduced oxygen content in our reduces

Cigarette smoke has carbon monoxide (CO). Because the affinity between carbon monoxide and hemoglobin is approximately 230 times more than the affinity between oxygen and hemoglobin, carbon monoxide rapidly binds with the hemoglobin, thus causing oxygen deficiency,

Hope this answer helps. :)

smoking tabacco in humans lead to oxygen deficiency as nicotin present in it reduces the heamabound oxygen thus causing a deficiency.

it causes deficiency of haembound oxygen by increasing the levels of carbonmonoxide
