What type of identification is NOT acceptable when purchasing OTC dextromethorphan?

When purchasing over-the-counter (OTC) dextromethorphan, identification is necessary to comply with laws aimed at preventing misuse. Acceptable forms of identification typically include those that are government-issued and contain a clear photograph of the individual, such as a passport, state driver's license, or military ID.

A school ID, on the other hand, is generally not deemed an acceptable form of identification for this purpose. This is largely because it is not issued by a government body and may not provide the level of verification needed to confirm age and identity reliably. Lawmakers emphasize the importance of preventing minors from accessing substances that can be misused, and thus restrict identification types to those that are most secure and verifiable.

In summary, the correct answer points to a type of ID that lacks the necessary authority and reliability to authenticate identity in the context of purchasing dextromethorphan, making it inappropriate in this scenario.
