> I strongly doubt there is any such thing as "medical-grade" marijuana. Actually, marijuana contains about 70 different cannabinoids. Different strains contain different ratios of these cannabinoids, and therefore different strains can be more (or less) effective for treating various ailments. Epileptics may require different strains from people suffering from chronic pain, for example. For people who have very specific medical needs, it is very helpful to have access to specific strains so that they can consume less and still reap the benefits.
