President Donald Trump (R) signed an Executive Order that reclassified marijuana from a Schedule 1 drug (highly dangerous and tightly controlled) to a Schedule 3 drug (not so dangerous, not so tightly controlled, but still illegal at the Federal level.
This is a mistake.
Leave aside all the dangers of modern-day marijuana or its unproven medical uses (multiple studies conflict with each other on the effectivity of a variety of constituent chemicals).
If the purpose really was to improve access for research (to, among other things, address those medical uses and those dangers), there was a simpler way to do that. Schedule 1 drugs are, in fact, deucedly difficult to obtain, even for researchers. However, that could have been addressed by setting up a licensing facility that would ease access to marijuana by approved laboratories and approved researchers working in those laboratories specifically on marijuana research.
It still can be. Trump’s EO can be rescinded, and that licensing facility still can be stood up.
