The abuse of cannabis and its consequences to mental health have been a subject of much debate in recent years. While the literature is replete with reports of mental disturbances following acute intoxications (1, 4, 7, 15), the mental health implications of long-term abuse of cannabis remain speculative (9, 13). Since the drug possesses psychotomimetic and hallucinogenic (8) properties, prolonged experimentation with cannabis on human subjects is undesirable. The clinical manifestations of disturbed mental functioning due to chronic abuse of cannabis can therefore be best observed in societies where the drug is taken as a pastime, generally to enjoy pleasant euphoria. Such a situation is found in India where the use of cannabis has become woven into the general philosophy of life over the years. The drug is particularly used at religious ceremonies, and sweets and non-alcoholic beverages containing varying quantities of cannabis are traditionally offered and consumed during the colour-throwing festival of Holi.
