Which of the following is NOT one of the 6 major categories of Controlled Substances?

The identification of antidepressants as not being one of the six major categories of controlled substances is correct because controlled substances are typically classified into categories based on their potential for abuse and accepted medical use. The primary categories include narcotics, depressants, stimulants, hallucinogens, cannabis, and anabolic steroids.

Antidepressants, while they are commonly prescribed medications that help manage mental health conditions like depression and anxiety, do not fall into the same classification system as controlled substances based on the potential for abuse. Most antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), are not classified as controlled substances under the same regulations that apply to narcotics and other drugs with a higher risk of dependency or abuse.

This distinction is important in the context of drug scheduling and regulatory compliance, where the focus is on substances that have a significant likelihood of abuse and associated public health risks.
