Final answer:
Schedule II drugs are required to have the warning label mentioned.
Step-by-step explanation:
The drugs required to have the warning "CAUTION: Federal law prohibits the transfer of this drug to any person other than the person for whom it was prescribed" on the container are Schedule II drugs. Schedule II drugs have a high potential for abuse and include substances such as opioids like oxycodone and fentanyl, as well as stimulants like Adderall.
