AnorexiaAnorexia is commonly characterized by a drastically reduced appetite, although it is often an indicator of a more serious psychological condition. Anorexia also commonly occurs as a secondary illness in patients suffering from AIDS, cancer, hepatitis, congestive heart disease, and depression, among others.

Medical marijuana may restore the appetite of patients suffering from anorexia. The analgesic effects of the plant may also reduce pain associated with other primary conditions in which anorexia is a secondary illness.
