Which medication is a Schedule III drug?

• A. Demerol
• B. Tylenol #2
• C. LSD
• D. Valium

Answer: (B)

Understanding drug scheduling helps you weigh abuse potential, medical use, and dependence risk. Schedule III drugs have an accepted medical use and a lower potential for abuse than Schedule II, with moderate to low physical dependence or high psychological dependence risk.

Tylenol with codeine fits this category because it combines acetaminophen with a small amount of codeine, giving it legitimate therapeutic use while keeping its abuse potential lower than stronger Opioids or pure codeine formulations. In contrast, Demerol is a pure opioid analgesic with high abuse potential and is placed in Schedule II. LSD is Schedule I, meaning it has no accepted medical use and high abuse potential. Valium is Schedule IV, which indicates even lower abuse potential than Schedule III.
