What does the term "Schedule II" refer to in controlled substances?

The term "Schedule II" refers specifically to substances that have a high potential for abuse, which can lead to severe psychological or physical dependence. Schedule II drugs are recognized for their medical use but are strictly regulated due to the risks they pose. Examples include opioids like oxycodone and stimulants like amphetamine, which are used in clinical settings but can be highly addictive.

The classification into Schedule II is part of the Controlled Substances Act, which categorizes drugs based on their accepted medical use and the potential for abuse and dependence. This regulation is essential for ensuring patient safety while allowing necessary medications to be available under stringent controls. Given their potential for abuse, Schedule II substances require a written prescription, and there are limitations on refills to mitigate the risks associated with misuse and addiction.
