Which substance is NOT classified under Schedule III?

Oxycodone is classified as a Schedule II substance under the Controlled Substances Act, which indicates that it has a legitimate medical use but also has a high potential for abuse and dependence. Schedule III substances, on the other hand, are considered to have a lower potential for abuse compared to those in Schedule II and may be prescribed more easily, with fewer restrictions.

Buprenorphine is a Schedule III substance because it is used for opioid addiction treatment and has a lower risk of dependence compared to Schedule II opioids. Ketamine is also classified under Schedule III due to its medical uses and lower potential for abuse relative to Schedule II drugs. Demerol, a brand name for meperidine, is categorized as a Schedule II substance due to its higher potential for addiction and abuse.

This knowledge of drug classification is pivotal in understanding the legal and medical frameworks for substances and how they are managed in clinical settings, particularly in the field of substance use and dependency treatment.
