Final answer:
Schedule I and Schedule II drugs have different levels of potential for abuse and accepted medical uses. Schedule I drugs have no accepted medical use and a high potential for abuse, while Schedule II drugs have accepted medical uses but also a high potential for abuse.
Step-by-step explanation:
Schedule I and Schedule II drugs both fall under the category of controlled substances and are regulated by the Drug Enforcement Administration (DEA) in the United States. However, they differ in their level of potential for abuse and their accepted medical uses.
Schedule I drugs have a high potential for abuse and no accepted medical use. Examples include heroin, LSD, marijuana, and ecstasy. These drugs are considered to have the highest risk and are strictly regulated.
Schedule II drugs also have a high potential for abuse, but they have accepted medical uses. Examples include morphine, oxycodone, and fentanyl. These drugs can be prescribed by doctors for legitimate medical purposes but are subject to strict regulations.
