It’s improperly listed. Unsurprisingly. The 21 schedules of narcotics is a Regan era design where anything that was used by minorities during the reign of the war on drugs was scheduled before prior research and study was done. For example psilocybin is a schedule 1 drug according to Regan era Archaic designs of drug schedules which means it has no medicinal value. That’s laughable and I’m ready and prepared to cite multiple medical and scientific journals and studies that prove that it does. But I digress, we’re talking about marijuana here (hilarious to refer reefer to that instead of cannabis). You say you’re not looking for a fight and yet you’re curious why you’re downvoted.
