Which of the following is NOT a classification of psychoactive drugs?

The classification of psychoactive drugs encompasses categories based on their effects on the central nervous system and how they alter mood, perception, and behavior. Narcotics, stimulants, hallucinogens, and inhalants are all recognized categories within this classification system based on distinct pharmacological effects.

Narcotics typically refer to opioid drugs that are primarily used to relieve pain and can induce feelings of euphoria, making them a classification of psychoactive drugs. Stimulants are substances that increase activity in the central nervous system, leading to heightened alertness and energy. Hallucinogens are known for altering perception, mood, and thought processes, often resulting in experiences that significantly distort reality. Inhalants involve substances that produce psychoactive effects when inhaled.

Each of these classifications serves to identify how specific substances interact with the brain and body, thus categorizing them within the broader field of substance use and abuse. Understanding these classifications is essential for recognizing the risks associated with different types of psychoactive drugs and their potential for misuse.
