Cannabis is the commonly used illicit drug of choice in South Africa and throughout the world. The majority of individuals who use cannabis do not report adverse reactions to it, however a minority of heavy users will develop problems. A substantial number of patients admitted at our psychiatry unit seem to be using cannabis.
AIMS
The aim of the study was to assess the relationship between cannabis use in psychiatric disorders in patients admitted in George Mukhari Hospital Psychiatry Unit, to determine the pattern of cannabis use, to identify the common psychiatric disorders in patients using cannabis, to determine the socio-economic factors that may lead to cannabis use.

A total of 75 participants admitted at Doctor George Mukhari hospital and diagnosed with psychiatric disorders according to the diagnostic and statistical manual of mental disorders fourth edition text revised were interviewed using a structured questionnaire and had urine specimens collected for analysis. Out of 75 participants a control group of 34 participants who tested negative for urinary cannabinoids were interviewed. The participants had signed a written informed consent in their language of preference. The study had been approved by the Research Ethics and Publications Committee of the University of Limpopo (Medunsa Campus).Data was analysed with the help of the statistician and reported on graphs, pie-charts and tables.
RESULTS

Most of the participants were of low socio-economic status and had started using cannabis early in their lives.
