GW Pharma is licensed by the UK. As far as Epidiolex getting FDA approval and DEA re-scheduling is concerned I don't think they have a prayer of actually getting approved. Management thinks that the approval process is based on evidence. But the DEA has been stonewalling phytocannabinoid medicines for 4 full decades. Short of Congressional action it isn't bloody likely to happen.

CARA's total flop was of synthetic cannabinoids.
