High CBD/low THC strains are absolutely referred to as MMJ. They're being specifically cultivated and researched for medical uses (especially for epilepsy) in Israel and elsewhere.
Also, calling the "medical" label a legal shield is bizarre. Medical cannabis is, as others commented, high-grade cannabis useful for treating serious conditions and helping cancer, AIDS, MS patients, etc.
I'm sorry but I don't think you are informed on this topic at all.
It's no big deal to me, but where I live, California, the phrase "medical marijuana" has been in general use for at least 15 years, with the meaning I indicated, whereas ISTR the high CBD/low THC strains are only about 2 years old.
ADDED. You seem to have taken my comment as an attack on the ability of people with medical problems to get marajuana, but it was not meant that way -- and in fact, I'm for sick people's having that ability -- though I have not made a deep analysis of the issue (and there is a chance that such a deep analysis would change my mind).
I just do not like to see a word that has been used in one way -- by many journalists and commentators and by the general public -- used in a confusingly different way.
