Which of the following categories of drugs is covered by the Controlled Substances Act (CSA)?

The Controlled Substances Act (CSA) specifically governs the manufacture, distribution, and use of certain drugs, categorizing them based on their potential for abuse and medical use. Hallucinogens fall within the scope of controlled substances due to their psychoactive properties and their potential for abuse. Many substances that are classified as hallucinogens, such as LSD and psilocybin, are listed under various schedules of the CSA, thereby subjecting them to federal regulation. This regulatory framework aims to prevent misuse and ensure that these substances are used in a manner that is safe and legal, under appropriate medical supervision.

In contrast, antibiotics, vitamins, and antidepressants do not fall under the same regulatory constraints of the CSA. While some antidepressants may be prescribed in a manner that requires careful monitoring, they do not possess the same potential for abuse as hallucinogens and thus are not classified as controlled substances. Antibiotics, being important for treating bacterial infections, and vitamins, which are essential nutrients, are also not considered to have abuse potential, and therefore, they are outside the purview of the CSA.
