We thank Stangl and Voigt for reminding us of the indoor carbon monoxide concentrations in shisha bars, which are potentially hazardous to health.

It is our view too that the risk potential is substantial, especially for the staff working in such establishments. The symptoms of chronic carbon monoxide poisoning include neurological (polyneuropathy), psychiatric (depression), and gastrointestinal (diarrhea) symptoms (2, 3); the indoor threshold of carbon monoxide concentration that would cause such symptoms is not known and depends on diverse comorbidities and factors of influence.

Because of the known risk potential of carbon monoxide, and the fact that measuring concentrations is fairly simple when using CO alarms, we support the call for further systematic studies and would make a plea for the compulsory fitting of suitable carbon monoxide alarms in shisha bars.
