Which of the following is a Schedule II controlled substance?

Cocaine is classified as a Schedule II controlled substance under the Controlled Drugs and Substances Act. This classification indicates that cocaine has a high potential for abuse and can lead to severe psychological or physical dependence. Schedule II substances are available for medical use, but strict legal regulations govern their handling, prescribing, and use.

Cannabis, on the other hand, falls under a different category since its legal status has changed significantly in various jurisdictions due to legalization for recreational and medical use. Psychedelics generally refer to substances like LSD or psilocybin, which may not fit within the same regulatory framework as Schedule II substances. Ketamine is classified differently as well, often associated with anesthetic use and research into its therapeutic applications, so it does not belong to Schedule II either.

Understanding these classifications is critical, especially within law enforcement and public safety contexts, as it aids in recognizing substances that pose significant risks and are subject to strict legal restrictions.
