Catatonia is a syndrome of specific motor abnormalities closely associated with disorders in mood, affect, thought and cognition. The principal signs of the disorder are mutism, immobility, negativism, posturing, stereotypy and echo phenomena. Catatonia is commonly seen in various psychiatric disorders, neurological disorders and certain medical conditions. It has also been reported in individuals with substance withdrawal. But we are presenting the case of a patient with cannabis dependence, who presented with symptoms of catatonia preceded by an increase in the amount of cannabis intake and resolution of the catatonia when he abstained from the substance. Literature review did not show any case revealing association between cannabis to catatonia.
