Final answer:
The category for drugs with a high potential for abuse and no accepted medical use is Schedule I, which includes drugs like marijuana and LSD, even though some states have legalized marijuana.
Step-by-step explanation:
The category for drugs with a high potential for abuse and no accepted medical uses under the Controlled Substances Act of 1970 is Schedule I. This category includes drugs like marijuana, LSD, and heroin. Despite certain states legalizing marijuana for medical and even recreational uses, under federal law, it is still classified as a Schedule I drug. This discrepancy between state and federal legislation leads to complex legal situations and potential federal legal actions against individuals and businesses in states where marijuana use has been legalized.
