Which of the following drugs is characterized by a high potential for abuse and is classified as Schedule I?

  1. LSD

  2. Oxycodone

  3. Fentanyl

  4. Codeine

The correct answer is: LSD

LSD, or lysergic acid diethylamide, is classified as a Schedule I controlled substance, indicating it has a high potential for abuse and no accepted medical use in the United States. Schedule I drugs are considered the most restricted category under the Controlled Substances Act due to their dangerous properties. This classification means that they are viewed as having a significant risk of addiction and pose a considerable risk to public health. The other substances mentioned—oxycodone, fentanyl, and codeine—are classified under different schedules. Oxycodone and fentanyl, which are powerful opioids, fall into Schedule II due to their medical uses but also a high potential for abuse. Codeine is generally classified as Schedule II or III depending on the formulation, indicating a lower potential for abuse relative to Schedule I substances. Thus, LSD stands out as the only drug listed that is classified as Schedule I, emphasizing its high potential for abuse without medical acceptance.
