Medical marijuana has been used in treatment in psychiatric conditions like anxiety, depression and mood disorders. These disorders affect the way an individual thinks and feels and acts and these acts are always negatively affected. The depression and anxiety disorders cause a deep feeling of sadness and result in loss of interest in even pleasurable activities. If this condition cannot be improved up on by change of life style, exercise and diet or by counseling it is necessary to provide relief with medication from the debilitating symptoms.

The proper use of medical marijuana many patients are able to avoid the use of opiates and tranquillizers or sleeping pills and other antidepressant medicines. It is argued that unlike other diseases, long suffering due to depression and anxiety disorders makes the patient will wear down the patient like no other disease and will deteriorate the condition as he looses interest in all activities that make recovery possible. In such cases, the mood elevation made possible by marijuana has a positive effect as the patient begins to take interest in activities that help to slowly recover; the mood improvement acts as a catalyst in the path to recovery.
