Which statement best describes Schedule I drugs?

• A. No medicinal use and cannot be prescribed
• B. Moderate potential for abuse and high psych dependence
• C. Lower potential for abuse and limited dependence
• D. High potential for abuse and severe psych or physical dependence

Answer: (A)

Schedule I substances are defined by having no accepted medical use in the United States and a high potential for abuse with no accepted safety for use. Saying they have no medicinal use and cannot be prescribed matches that definition, because a prescription implies a medical indication and an approved medical use. In practice, these drugs are illegal to prescribe and are typically restricted to approved research. The other descriptions describe substances with some medical use and varying levels of abuse or dependence, which is not true for Schedule I.
