Clogged arteries: Toxic chemicals in cigarette smoke can clog arteries (atherosclerosis). Nicotine can further narrow the arteries by causing muscle around the arteries to go in to spasm. If it affects the arteries supplying blood to the brain, one can experience these symptoms. Stop smoking and seek medical help.
