Recreational use of psychoactive drugs by patients with cystic fibrosis.
We assessed unprescribed psychoactive drug use in 173 adults with cystic fibrosis. Twenty (11%) regularly smoked tobacco. Cigarette smoking ranged from 1 to 30 years (2 to 60 pack-years). Alcohol was used by 60%, and marijuana by 20% of the patients. Pulmonary symptoms were often increased the day after alcohol ingestion. Alcohol occasionally caused nausea, vomiting, and headache if the patient was taking some cephalosporin derivatives (such as cefsulodine) or chloramphenicol. Marijuana often aggravated chronic pulmonary symptoms, although some patients reported transient relief during use. Comparison with a retrospectively selected control group did not show faster short-term pulmonary deterioration in the tobacco smokers. Physicians who deal with cystic fibrosis and other chronic illnesses should be cognizant of interactions of unprescribed and prescribed drugs. Recreational use of unprescribed psychoactive drugs should be considered if unexpected symptoms occur in older patients.
