Smoking and second-hand smoke from cigarettes, cigars, and pipes can contribute to headaches for both the smoker and the non-smoker. Nicotine, one of the components of tobacco, stimulates vascular activity in the brain. Smoking also stimulates the ganglion nerves in the back of the throat, contributing to headache pain. In some people, this stimulation can contribute to headaches. Usually, by removing the stimulus (nicotine), headaches will be relieved. Quitting smoking or reducing exposure to secondhand smoke is especially helpful for those with cluster headaches. In one study of patients with cluster headaches, those who reduced their tobacco use by less than one-half pack of cigarettes per day found their headaches were decreased by 50 percent.
Allergy to smoke, as well as odor sensitivity, can also cause migraine headaches in some people. By avoiding situations or places where smoking is permitted, or by quitting smoking, most people can reduce the onset of migraine headache.
