Abstract
Bipolar disorder patients have a high prevalence of drug use, being cannabis one of the main drugs involved. Cannabis use can modify clinical characteristics and outcome of this disorder. The aim of the current work is to evaluate from longitudinal studies the influence of cannabis use in the outcome of bipolar disorder. A systematic review was carried out through a Medline searching. 5 papers were found on bipolar patients cohorts that study this effect. Cannabis use is a negative prognostic factor, it was associated with less sucessful clinical recovery, worse global functioning, more time in affective episodes, and probably, more often rapid cycling and manic/mixed episodes. Bipolar patients who stop using cannabis show a better outcome. Alcohol and other drugs use are common between cannabis users and are associated with a negative outcome.
