Randomized controlled trial of a cannabis‐focused intervention for young people with first‐episode psychosis

Abstract

Objective:  To evaluate a cannabis‐focused intervention (cannabis and psychosis therapy: CAP) for patients continuing to use cannabis following initial treatment for first‐episode psychosis (FEP).Method:  Consecutive admissions to an early psychosis program were screened and consenting individuals using cannabis in the 4 weeks prior to assessment participated. A single‐blind randomized controlled trial compared CAP (n = 23) with a clinical control condition (psychoeducation, PE; n = 24).Results:  There were no significant differences between the CAP and PE groups on cannabis use at end of treatment and 6 months post‐intervention. There were no significant group differences on psychopathology..
