Which drug classification would LSD fall under?

LSD, or lysergic acid diethylamide, is classified as a Schedule I substance under the Controlled Substances Act in the United States. This classification is reserved for drugs that have a high potential for abuse and no accepted medical use in treatment in the United States. Schedule I substances are considered to present a high risk of dependence and are tightly regulated, meaning they cannot be prescribed or dispensed legally for medical purposes.

The characteristics of Schedule I drugs include a lack of accepted safety for use under medical supervision and a high potential for abuse. LSD fits this description due to its potent effects on mental perception and sensory experiences, alongside the legal restrictions surrounding its use. In contrast, other classifications, like Schedule II, III, or IV, include substances that have some accepted medical uses but also possess varying degrees of potential for abuse or dependence. Thus, the classification of LSD as Schedule I highlights both its unique properties and regulatory status.
