I believe that different cbd:thc/other cannabinoid/terpenoid ratios work best for different ailments/folk. But I'm of a whole plant mentality, for wellness. Isolating specific cannabinoids is not the answer. I'm with Mechoulam's "Entourage Effect" idea, which is why I think synthetic single cannabinoids market is a half-baked idea.
The closest big pharma has come, to date, with a whole plant approach, is GW Pharma, with their Sativex (and future) products, using whole plant extracts, combined in different ratios, for different ailments.
For those that don't like:don't want to get high, a la THC, I recommend a whole plant approach that sees people juicing the leaves, and ingesting flowers (oil, capsules, tinctures, etc...) of low-THC:high-CBD phenos of specific strains, such as Cannatonic, or Z7 from Shantibaba, or R4 "Charlotte's Web" from the Stanley Bros, or Harlequin, etc...
I'm a strong proponent of daily juicing, specifically raw green juices that include cbd-rich cannabis leaves, especially for people suffering from auto-immune diseases....they've absolutely changed my life!
I've been strain hunting since 2011, finding a stable of high-CBD strains, to deal with my own auto-immune disease.
