MJNA doesn't have a raw materials supply chain
The only raw materials supply chain that MJNA had was the PhytoSphere industrial hemp CBD operation that they sold to CannaVest last year.
HempMedsPx is a marketer and distributor of finished goods in the U.S.A (and possibly Canada)
Canipa Holdings does the same for Europe
Kannalife sources its pharmaceutical CBD from another company
CanChew is working on a THC gum, I think in Europe, but that's a few years away
CannaVest is a separate company that arranges to grow industrial hemp overseas, process it into CBD paste, import it, refine it into CBD oil, some of which is used in manufacturing its own products (Cibaderm, Cibdex, RSHO, etc), and the rest sold to other companies, like HDDC (which owns 43% of MJNA) for the use in products for which HDDC owns the trademarks, like HempVAP and Cannabis Beauty DEFINED.
MJNA doesn't have a supply channel of its own, as best as I can tell.
Regarding the newest article on Seeking Alpha, that author is making the same point that I and others, like Alan Brochstein, deafelephant, et al, have been making for months, that MJNA has built a firewall between itself and Dixie Elixirs, and won't remove it until the federal laws change.
