In the collective unconscious, a patient with cystic fibrosis does not smoke. This belief is so deeply rooted that there is virtually no French data on the prevalence of smoking among this vulnerable population.

Faced with a cohort of patients undergoing a complete transformation (improved quality of life and life expectancy, fewer hospitalizations, reduced respiratory symptoms, better social integration), it is becoming urgent to assess the current situation in order to optimize tobacco prevention.

This is all the more important given the emergence of international studies objectively examining the interactions between smoking, vaping, and the efficacy of Kaftrio.
