Taub S, et al. - The present study sought to compare patterns of cannabis use among people with Major Depressive Disorder (MDD) and Bipolar Disorder (BPD). Results of this study suggested that people with BPD could present more intensive patterns of cannabis use compared to those with MDD.

Methods

• Information was drawn from Wave 1 (2001-2002) of the National Epidemiologic survey on Alcohol and Related Conditions (NESARC).
• Cannabis users who qualified for a diagnosis of past-year MDD (N=217) were contrasted with those with BPD (N=168) in frequency and daily dose of cannabis use, rates of comorbid psychiatric disorders including specific criteria of cannabis use disorders (CUDs), treatment utilization and suicidality.

Results

• Among past-year cannabis users, people with BPD reported using cannabis more frequently and smoking more joints per day compared to those with MDD.
• The findings suggested that they were also more likely to suffer from comorbid personality disorders and qualify for specific CUD-criteria, incorporating use in physically hazardous situations and unsuccessful efforts to control substance use.
