Brazilian suicide-death study finds cannabis detection clustered in vulnerable…
Cannabis detection in postmortem toxicology among suicide decedents in the Federal District, Brazil, 2009-2019.
AI Summary
This population-based cross-sectional study examined factors associated with postmortem cannabis detection among 1,164 people who died by suicide in Brazil’s Federal District from 2009 to 2019 and had toxicology data. Cannabis was detected in 7.8% of cases. Because the study is observational, its findings describe associations, not evidence that cannabis caused or contributed to suicide deaths.
After adjustment, detection was more common among decedents aged 12–17, those with a prior criminal offense record, cases from 2016–2019, and cases with concurrent cocaine detection. The authors say these findings identify subgroups for surveillance and screening, but the study cannot establish why cannabis was detected or whether it played any role in the deaths. This is an abstract-based summary; the abstract does not provide details about the toxicology methods or other limitations of the full study.
