Medical cannabis

Cannabis sativa L. (marijuana; hemp) used medicinally

Medical cannabis, medicinal cannabis or medical marijuana (MMJ) includes cannabis products and cannabinoid molecules that are prescribed by physicians for their patients. The use of cannabis as medicine has a long history, but has not been as rigorously tested as other medicinal plants due to legal and governmental restrictions, resulting in limited research to define the safety and efficacy of using cannabis to treat diseases. There is mixed and inconclusive evidence on the benefits of cannabis-based medicines, frequent mild adverse effects, and generally low-to-moderate quality of evidence.
