Mr H,

UK company GW Pharmaceutical has medicine for multiple sclerosis and Zelda and other companies are targeting other diseases, but is the medicine a specific strain of cannabis plus some added man made chemicals that target the specific disease. Surely it cant just be the same MM medicine for many diseases.

What makes GW Pharmaceuticals patented multiple sclerosis medicine so special?

Oh and yes GLN and Zelda deal looks to be off. They are two months behind the timetable.
Too difficult to get so many scientists from so many countries to come together.
