They are identical classifications
Schedule II has high abuse potential with accepted medical use; Schedule III has moderate abuse potential with accepted medical use (Correct answer)
Schedule II is available without prescription
Schedule III is more restricted than Schedule II

Correct answer: Schedule II has high abuse potential with accepted medical use; Schedule III has moderate abuse potential with accepted medical use
