What is considered a "controlled substance"?

A controlled substance is defined as a drug that is regulated by law due to its potential for abuse and risk of dependency. This classification includes various substances that are subject to strict regulations to prevent misuse, including narcotics, stimulants, and some depressants. The legal framework governing controlled substances aims to balance the need for access to medications that can benefit patients while minimizing the risks associated with their use.

On the other hand, over-the-counter medications, dietary supplements, and certain prescription medications for chronic illnesses do not fall under the controlled substances category. Over-the-counter medications are generally considered safe for public use without a prescription and are not associated with high potential for abuse. Dietary supplements are regulated differently and do not have the same potential for dependency as controlled substances. Prescription medications for chronic illnesses may include drugs that are not classified as controlled substances, depending on their potential for abuse and how they are regulated. Therefore, the definition of a controlled substance hinges on its regulation due to potential for abuse, making it a crucial area of knowledge for pharmacy technicians.
