In brief: Many reasons
Inhalation of cigarette smoke infuses carbon monoxide, particulates, nicotine, carbon dioxide, and many other gases into the lungs with almost instantaneous absorption into the blood (bolus effect) going right to the brain, leading to transient decreases in brain oxygen.
This causes dizziness or syncope.
