Can smoking ciggarettes make you faint?
3 doctors weighed in across 2 answers
Yes, by several...: ...Mechanisms: (1) decrease of oxygen carried by the blood, (2) hyperventilation to compensate for that, and (3) nicotine effect on the heart.

Hypooxygenation.: Our red blood cells have a higher affinity for carbon monoxide, found in cigarettes (along with about 42 carcinogens), than for oxygen, so smokers can have low levels of oxygen in their blood. This could make one feel faint at times.
