Which factor is not used to determine drug schedules?

• A. Color of the drug
• B. Scientific knowledge
• C. Addiction rate
• D. Psychoactive ability

Answer: (A)

Scheduling is based on how likely a substance is to be abused, whether it has an accepted medical use, and its safety and dependence risks, all grounded in scientific evidence. The psychoactive ability matters because a drug that significantly alters brain function tends to carry higher abuse and harm potential, influencing its schedule. The addiction rate reflects dependence potential, another key factor in classification. Scientific knowledge guides updates as new data on risks and medical usefulness emerge. The color of a drug, however, is just a visual attribute and does not inform its pharmacology, safety, or medical use, so it isn’t used to determine schedules.
