Recent research digest. 4 of 4 most recent studies from our monitored feeds. CED Clinical Relevance #81 Research Authority Correlates and Predictors of Criminal Legal Involvement in People With First-Episode Psychosis. *Scanlon Faith et al.* The Journal of clinical psychiatry • 2026 # Clinical Summary This study examined criminal justice involvement in people experiencing their first episode of psychosis and identified rates, risk factors, and predictors of such involvement both before and during a two-year treatment period. Understanding these patterns helps clinicians recognize which early psychosis patients may be at higher risk for legal involvement so they can implement appropriate preventive interventions.

This finding explains why high doses of THC cause anxiety by identifying the specific brain pathway and molecular mechanism responsible for this adverse effect.

The study systematically analyzed evidence from 2014-2024 to inform clinical decision-making about high-potency THC cannabis products. [PubMed](https://pubmed.ncbi.nlm.nih.gov/41918345/) | [PMC PDF](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6344428/) CED Clinical Relevance #84 Research Authority The association between major depressive disorder and [cannabis use disorder](https://cedclinic.com/sex-differences-cannabis-stress-reactivity-oxytocin/): A meta-analysis and meta-regression analysis. *Pini Alemar João et al.* Journal of psychiatric research • 2026 # Clinical Summary People with cannabis use disorder are significantly more likely to have major depressive disorder than the general population, and this relationship appears to work both ways, with depression increasing the risk of developing cannabis problems. The strength of this association varies across different studies and populations, suggesting that factors like treatment setting, geographic location, and how depression and cannabis use are measured all influence whether these two conditions occur together.
