Cannabis-Induced Diffuse Alveolar Haemorrhage: A Case Report From the Intensive Care Unit

Year: 2026

Type: article

Abstract: Diffuse alveolar haemorrhage (DAH) is a syndrome characterised by acute dyspnea, respiratory failure, diffuse alveolar infiltrates, haemoptysis, and anemia, which can be fatal without prompt treatment. We present the case of a 26-year-old man with a clinical presentation of DAH and cannabis consumption. After investigation, other aetiologies were ruled out, suggesting cannabis use associated with a viral respiratory infection as the most probable cause. Cannabis consumption has been previously documented in the literature as a potential trigger for DAH. Although rare, the clinical severity of this condition and the rising prevalence of cannabis use highlight the importance of raising awareness regarding this potential causal relationship.
