Abstract

ObjectiveAlthough cannabis use among individuals with psychotic disorder is considerable, little is known about patterns of use and factors contributing to continuation of use. Therefore, we investigated craving in relation to cannabis use in patients with psychotic disorder and healthy controls. MethodThe study included 58 patients with non-affective psychotic disorder and 63 healthy controls; all were frequent cannabis users. Craving was assessed with the Obsessive Compulsive Drug Use Scale (OCDUS) for cannabis, as well as in daily life using the Experience Sampling Method (ESM). ResultsPatients scored higher on the OCDUS (B=1.18, P=0.022), but did not differ from controls in ESM indices of craving (all P>0.05). In daily life, ESM craving predicted cannabis use and this was stronger in controls ((2)=4.5, P=0.033; B-controls=0.08, P
