My understanding is that it is possible, but involves a lot of bureaucratic red tape.

I imagine that in some locales, the political climate is such that what Thriptic is saying is quite the reality -- it is much too risky. That being said, with acceptance of cannabis legality growing, there does seem to be a shift where more formal organizations are involved in research, like the CMCR (https://www.cmcr.ucsd.edu/ https://www.cmcr.ucsd.edu/) mentioned in the Factcheck article. CMCR is located in the University of California in San Diego -- it is not surprising to find out that a formal research base is in a state more politically and legally friendly to cannabis.
