A South African study finds that people with schizophrenia and other psychotic disorders who use cannabis experience more severe psychosis and face a higher risk of relapse. The research focuses on patients admitted for psychotic conditions and reports that cannabis use is common among this group.
The outlets describe cannabis use in the context of clinical outcomes, including symptom severity and the likelihood of returning to acute episodes. While the reporting emphasizes the association between cannabis and worsening mental health outcomes, it does not present evidence that cannabis is the sole or direct cause. The accounts also note that cannabis use is widespread among people in treatment for psychosis, highlighting the relevance of the findings for clinicians and patients.
