Aims:
This primary study was performed to determine the prevalence rate of cannabinoid consumed in Kerman (Iran).
Measurements:
Urine samples of 700 males, referred to a clinical lab in Kerman city were collected for detection of cannabinoid metabolites. Assessment analysis was a monophasic immunoassay rapid technique. The study was completely blind and only age and residence of samples were revealed. All stages were confirmed and supervised by the ethics committee.
Results:
The prevalence of cannabinoid use was 0.6%. All four positive cases were urban, with ages 31, 36, 40 and 67. More than 90% of referred cases were urban with mean age of 46.8+/-16 while the mean age of rural cases was 54.3+/-17 years.
Conclusions:
Considering the age range and possibility of the underlying disease in the study population, the prevalence of cannabinoid use was more than what was expected. Urine analysis as a method for assessing the prevalence rate requires a wide sample size and age distribution matching the age distribution of the study population. In addition, the entrance criteria should not include sick cases.
