Which category includes ketamine or testosterone?

• A. Schedule I
• B. Schedule II
• C. Schedule III
• D. Harrison Act of 1914

Answer: (C)

Under the drug scheduling framework, substances are grouped by medical use and how strongly they can be abused. Schedule III includes drugs that have an accepted medical use and a lower potential for abuse than Schedule II, with a risk of dependence that is moderate to low (or primarily psychological). Ketamine has legitimate medical uses as an anesthetic and for pain management, and testosterone is a medically used hormone; both fit this category because their abuse potential is not as high as Schedule II substances. The Harrison Act of 1914 isn’t a scheduling category at all; it was an early tax and regulation statute for opiates and coca products, not part of the modern CSA schedules.
