Which of the following best describes Schedule I drugs?

Schedule I drugs are characterized by their high potential for abuse and lack of accepted medical use in treatment within the United States. This classification means that these substances are often referred to as "street drugs," and they carry significant legal restrictions. Examples of Schedule I substances include heroin, lysergic acid diethylamide (LSD), and cannabis, which are illegal to produce, distribute, or possess for medical purposes according to federal laws.

In contrast, prescription medications fall into various schedules based on their potential for abuse and medical use, and over-the-counter drugs are available without a prescription, typically considered safe for general use. Controlled medications with a low potential for abuse are classified under lower schedules (like Schedule IV or V), where restrictions are less stringent than for Schedule I drugs. Understanding these classifications is important for proper medication management and compliance with legal regulations.
