Medical Cannabis: A Complex Question
The National Multiple Sclerosis Society in the US takes the view that the question of whether marijuana — produced from the flowering top of the hemp plant, cannabis Sativa — should be used for symptom management in MS is a complex one.

Still, there are uncertainties about the benefits of marijuana relative to its side effects.
