The US government is now in thrall to the Kratom industry though isn't it? No reason to expect any logical consistency from them.
(Literally the person currently responsible for the branch of government that keeps illegal drugs out of the country is an investor in a Kratom company)
The most ridiculous thing about cannabis remaining schedule 1 (high risk of abuse, no known medical use) so long is that there is both prescription THC and CBD. It should have been changed|to a higher (less strict) schedule decades ago with the release of marinol in 1985. Then we could have had a lot more studies being done. Needless to say, not easy to do studies on schedule 1 drugs.
the two week hearing happening now mentioned marinol, with the DEA throwing its support behind that and rescheduling to schedule III, following the administration's policy aims (only mentioning because the head of DEA was anti-rescheduling before being appointed, spineless haha but I'm glad he's not in the way)
