Phencyclidine (PCP) is classified as which scheduled substance?

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

Answer: (A)

Phencyclidine (PCP) is a Schedule II controlled substance. This category is used for drugs that have a high potential for abuse but do have some accepted medical use with strict controls. PCP’s history as a dissociative anesthetic explains why it’s tightly regulated today, even though it is not widely used medically. This places it in the same high‑risk schedule as other potent drugs that require strong controls, rather than in the most restrictive Schedule I, which is reserved for substances with no accepted medical use.
