Intra-Alveolar Hemorrhage of Unusual Etiology

Cannabis use is steadily increasing worldwide and is an emerging public health problem. This consumption is responsible for harmful respiratory effects, including intra-alveolar hemorrhage. We report the case of a 26-year-old man admitted with exertional dyspnea and profuse hemoptysis. Investigations revealed intra-alveolar hemorrhage. Immunological and tuberculosis tests were negative. When the case history was taken again, it was noted that the patient had been a regular cannabis user for several years, and the blood and urine tests for toxic substances revealed the presence of tetra-hydro-cannabinoids. This case illustrates the seriousness of respiratory complications caused by cannabis, and highlights the need to emphasize the importance of weaning and educating young people.
