Which category of drugs does NOT fall under the 'dangerous drugs' definition?

The term 'dangerous drugs' typically refers to substances that have a high potential for abuse, dependency, or adverse health effects. In the context of the options provided, over-the-counter medications do not fit this classification.

Over-the-counter medications are available without a prescription and are generally considered safe for public use when taken as directed. They do not typically have the same potential for abuse or signify the same risks as scheduled narcotics or anabolic steroids, which are closely regulated due to their potential for misuse and health risks. Prescription medications can also fall under the definition of dangerous drugs, as they often contain substances that require careful handling and monitoring due to their effects.

Thus, over-the-counter medications stand apart as a category that does not typically align with the characteristics of dangerous drugs, making this the correct choice in the context of the question.
