Which drug schedule has no current accepted medical use?

• A. Schedule II
• B. Schedule III
• C. Schedule I
• D. Schedule IV

Answer: (C)

Drug scheduling reflects how medical use and abuse potential are weighed in assigning a drug to a category. The category with no currently accepted medical use in the United States is the one that is reserved for substances without any approved medical purpose and a high potential for abuse; these drugs are not prescribed and are tightly restricted to research settings. That is why this option is the best choice. Other schedules do have accepted medical uses, even though they carry varying risks of misuse. For example, some high-potential drugs still have legitimate medical applications under strict controls, and lower-schedule drugs have clear medical uses with less risk. This distinction—no accepted medical use versus established medical use with varying abuse potential—defines the correct answer.
