Psychosis: Cannabis‐induced, cannabis‐concurrent, or primary?
The Brown University Child & Adolescent Psychopharmacology Update September 1, 2020 DOI: 10.1002/cpu.30517
Summary
AI-generated from the abstractDistinguishing primary psychosis from cannabis intoxication and cannabis-induced psychosis is difficult yet clinically important, because nearly half of cannabis-induced psychosis cases precede primary psychosis. A fictional case study illustrates these diagnostic challenges, but the article's main focus is on practical methods for differentiating the three conditions. The authors, Canadian psychiatrists, provide guidance for clinicians facing these overlapping presentations.

Abstract
Telling the difference between primary psychosis, cannabis intoxication, and cannabis‐induced psychosis is challenging but important, especially now that it's known that almost 50% of cannabis‐induced psychosis precedes primary psychosis. A fictional case study reported in Paediatrics & Child Health makes these challenges come to life. But the purpose of the case study is only as an introduction to the meat of the article, which is how to differentiate between the three. The authors are psychiatrists from Canada.
