What classification includes both morphine and amphetamines?

The correct classification that includes both morphine and amphetamines is Schedule II. This schedule comprises substances that have a high potential for abuse, which can lead to severe psychological or physical dependence. Both morphine, an opioid analgesic, and amphetamines, which are central nervous system stimulants, fall into this category due to their medical uses and significant potential for abuse and addiction.

Schedule II drugs are strictly regulated; they require a written prescription from a licensed healthcare provider and cannot be refilled. This reflects the balance between their therapeutic benefits and the risks associated with their misuse. Recognizing the abuse potential of these drugs is crucial for regulating their prescription and ensuring patient safety.

In contrast, Schedule I substances are defined as having no accepted medical use and a high potential for abuse, whereas Schedule III and Schedule IV substances have lower abuse potentials and different regulatory requirements. Understanding these classifications is essential for comprehending federal drug regulations and ensuring compliance in pharmacy practice.
