Which schedule includes drugs like morphine and oxycodone, known for their high abuse potential?

The correct choice, which is Schedule II, is accurate because this schedule is specifically designated for drugs that have a high potential for abuse, which can lead to severe psychological or physical dependence. Morphine and oxycodone are prime examples of medications classified in this category.

Drugs in Schedule II are available only through a prescription and have strict regulations surrounding their distribution and usage. They are often utilized for legitimate medical purposes, such as pain management, but their potential for abuse necessitates careful monitoring and control by healthcare professionals.

In contrast, Schedule I drugs are classified as having no accepted medical use in the United States and a high potential for abuse, making them illegal to prescribe or use medically. Schedules III and IV contain drugs that have a lower potential for abuse compared to those in Schedule II. These lower schedules include medications that may be prescribed but are considered less risky in terms of dependency.
