Keywords: "derived from"...

And the "mixture of compounds" is just THC and CBD, the same as literally hundreds of MMJ products, many of which are now being grown organically under strict, controlled conditions and offered without the following additives of Sativex:

Extraction solvent: Liquid carbon dioxide
Excipients: Ethanol anhydrous, Propylene glycol

Currently, Sativa would cost patients about $14,000 for an annual prescription give or take and we should expect insurance companies to fight tooth and nail to avoid covering it with the exception of terminal cancer or MS while many of us would wait around, literally suffering in pain either from our neurological deficits or from side-effects of many of the barbaric pharmaceuticals prescribed to us.

I presume this will all change over time as more data comes out in support of cannabis-based medicines and more products are brought to market.
