In Morocco, as in other countries, the cannabis consumption by a great number of the population remains worrisome, in terms of its effects on “mental and physical” health and its social repercussions.

To determine the profile of the people poisoned by cannabis in Morocco in order to identify individuals and groups at high risk.

A retrospective study was conducted on chronic cannabis poisoning cases notified between 2000 and 2008 in the Morocco Poison Control Center.

During the study period, three hundred and one regular users of cannabis (28 women and 273 men) were poisoned, constituting 34 cases on average per year. The clinical symptoms presented by victims are different, depending on the quantity of inhaled and absorbed psychoactive substances (especially THC) and the frequency and method of use. The average age of victims is 22 years. Among the 225 patients for whom the evolution is known, a 23-year-old man died. The rest of the patients’ condition has improved under gut decontamination.
