Objective: To look at cigarette smoking history (personal and secondary exposure as a child) in non-cluster headache trigeminal autonomic cephalalgias seen at a headache clinic and to determine smoking exposure prevalence utilizing previously published data.

Methods: Retrospective chart review and PubMed/Google Scholar search.

Results: Forty-eight clinic patients met ICHD-3 criteria for non-cluster headache trigeminal autonomic cephalalgias. Four had paroxysmal hemicrania, 75% were smokers and secondary exposure was noted in all. 16 patients had short lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) or short lasting unilateral neuralgiform headache attacks with autonomic symptoms (SUNA), 12.5% were smokers and secondary exposure was noted in 91%. Twenty-eight patients had hemicrania continua, 21% were smokers and secondary exposure was found in 62.5%.Since 1974 there have been 88 paroxysmal hemicrania, 50 SUNCT or SUNA and 89 hemicrania continua patients with a documented smoking exposure history. From current data and previous studies, a smoking history was noted in 60% paroxysmal hemicrania, 18% SUNCT and SUNA and 21% hemicrania continua patients.

Conclusion: A cigarette smoking history appears to be connected to paroxysmal hemicrania (personal and secondary exposure) and possibly to SUNCT/SUNA (secondary) and hemicrania continua (secondary).
