Results: Hospital data scanning results showed 392 patents estimated for cannabis abuse suspicions throughout 4 year, among whom 75 patients were for positive urine drug testing.

Men made up 86. 2 % of the patients, the average age of users didn’t change significantly in four years with mean age of 17 years old.  The percentages of cannabis users increased  in years; and the winter was found to be  the most prevalent season.

Majority of the patients (49.3 %) were from forensic medicine out clinic

Patients admitted to the hospital were discharged on the same day.

None of the patients died.
