Controlled substances are classified this way because they have a significant potential for abuse and dependence. This classification is regulated under various laws and frameworks, such as the Controlled Drugs and Substances Act in Canada. Drugs in this category often include narcotics, stimulants, and depressants that can lead to physical or psychological dependence when misused.

The requirement for a prescription helps manage and monitor usage, ensuring that these drugs are only dispensed to individuals who need them under the supervision of a healthcare professional. This regulation aims to prevent misuse, promote safe treatment practices, and minimize the risks associated with these powerful medications.

In contrast, over-the-counter medications are available without a prescription due to their generally recognized safety when used as directed. Herbal supplements often do not require prescriptions as they are considered alternative treatments, often used with fewer restrictions. Antibiotics, while requiring a prescription to ensure appropriate use and to combat antibiotic resistance, do not inherently have the same level of abuse potential as controlled substances. Therefore, the identification of controlled substances as requiring a prescription is fundamental to protecting public health and safety.
