What is the definition of a "dangerous drug" according to New Mexico law?

The definition of a "dangerous drug" according to New Mexico law encompasses specific substances that may pose a significant risk to public health and are subject to regulatory control. This definition aligns with the idea that these drugs require careful oversight due to their potential for abuse or harmful effects.

Option C, referencing substances like ephedrine, is correct because New Mexico law specifically identifies certain drugs that have the potential for misuse and are classified under distinct regulations. This classification includes substances that can impact the central nervous system or have a high potential for addiction or adverse side effects. By recognizing such substances, the law aims to ensure proper use and minimize risks associated with them.

In contrast, the other options do not accurately capture the legal definition of "dangerous drugs" within the state. While requiring a prescription indicates that a drug poses some level of risk, the criterion for a dangerous drug is more stringent than merely requiring a prescription. Additionally, the option about drugs purchased with a pharmacist's recommendation does not encompass the full scope of what constitutes a dangerous drug. Lastly, labeling all recreational drugs not approved by the FDA as dangerous misrepresents the legal definition, as some of those substances may not meet the criteria for classification as "dangerous drugs" under New Mexico law.
