Schedule 1 substance research has long had far more 'propaganda machine' orientation than science orientation however with the agenda transparently reflected in studies.
All of the giving spiders drugs studies to look at their webs while it may have some slight neurological value ignored the bleeding obvious with some examples like the 'caffeine' webs.

Of course those webs looked sparse, caffeine is a known neurotoxin to insects! That is why plants produce it in the first place and spiders wouldn't even have much reason to develop a resistance given most species have a carnivorous diet, their prey would have more of a reason to and prey that is dying of neurotoxin would be far less likely to survive to land in their web. Perhaps caffeine's inclusion among the study was a snide point on someone's part about the applicability of spider models to vertebrates.
Meanwhile they knew about MDMA use therapeutically yet it took to the 10's to start using it for PTSD again in clinical trials. Sorry lost generations of veterans - there was another war for you to be a casualty of.
It is still having politicians try to practice science - and I'm not sure how applicable those two are when they were dragged from them kicking and screaming essentially. It is still a political process instead of a scientific one.
