What types of substances are considered legal, yet potentially abusive?

The selection of alcohol, prescription drugs, and over-the-counter drugs accurately reflects the substances that are legal to purchase and use, yet they can be misused or abused.

Alcohol is a widely accepted social substance, but excessive consumption can lead to addiction, health issues, and impaired judgment. Prescription medications, while beneficial when taken as directed for legitimate medical reasons, have the potential for abuse if taken improperly or by individuals for whom they were not prescribed. Over-the-counter medications, though generally safe when used as instructed, can also be abused, particularly certain types like cough syrups or pain relievers, which can lead to adverse effects or dependency.

The other options focus on more restricted categories or do not encompass the full scope of substances that, while legal, can lead to abuse. For a comprehensive understanding of substance abuse potential, it is important to recognize this broader category that includes multiple forms of readily available substances.
