LSD is an example of which CSA schedule?

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

Answer: (C)

LSD is classified as Schedule I because this category is reserved for substances with a high potential for abuse, no currently accepted medical use in treatment in the United States, and a lack of accepted safety for use under medical supervision. LSD has long been viewed as having a high risk of misuse and, at least in practice, has no approved medical use, which fits Schedule I criteria. This distinguishes it from other schedules: substances in Schedule II have medical uses but with strict restrictions due to abuse potential; Schedule III has medical use with moderate to low potential for abuse; Schedule V has the lowest potential for abuse and accepted medical use.
