Phencyclidine (PCP) is classified as a Schedule I substance. This classification is based on several criteria, including its high potential for abuse, lack of accepted medical use in treatment in the United States, and absence of accepted safety for use under medical supervision. Schedule I substances are deemed to have no legitimate medical purpose and carry the highest levels of restrictions.

This classification reflects the historical and pharmacological context of PCP, which was originally developed as an anesthetic but was withdrawn from the market due to severe side effects and potential for abuse. Its use outside of a controlled setting has led to significant public health concerns, further solidifying its position as a Schedule I drug under the Controlled Substances Act.

In summary, understanding the scheduling of drugs like PCP highlights the legal and health implications of substance use and provides a framework for substance control policies, education, and prevention strategies.
