title: [Tobacco brand-related headache].
abstract: BACKGROUND
  Tobacco smoking has been considered a risk factor for headache by some authors, while others disagree because of contradictory data.
  
  
  RESULTS
  We describe the clinical aspects of eleven patients (four men and seven women) who presented to us with tobacco brand-related headaches. Clinical history help us to discover that headache of each patient was directly related with certain cigarette brands smoking. The cigarette brands implicated were diverse and different for each patient. Headaches were migraine-like in seven cases, cluster-like in three, and non-specific in the other one. They disappeared after switching brand or stopping smoking.
  
  
  CONCLUSIONS
  In our patients, headaches were clearly related to smoking certain brands of cigarettes, which has never been reported before. This type of headache has characteristics that suggest that it could be a particular form of chemical odour intolerance, previously described. The number of possible responsible substances is large. More studies will be necessary in order to discover the mechanism leading patients to tobacco brand-related headache. It is important to ask our patients which cigarette brand they smoke, so it is possible to solve the problem.
