How should a mixture containing pure codeine powder and Tylenol with Codeine Elixir be classified?

The mixture containing pure codeine powder and Tylenol with Codeine Elixir should be classified as a Schedule III controlled substance. The rationale for this classification is based on the concentration of codeine in the mixture.

In the context of controlled substances, codeine is classified under Schedule II when it is in its pure form or when it is present in specific high doses in a formulation. However, when codeine is combined with other non-narcotic ingredients, as in the case of Tylenol with Codeine Elixir, the classification can change. Specifically, preparations that contain not more than 90 milligrams of codeine per dosage unit are categorized as Schedule III substances.

Thus, while pure codeine and higher concentrations might lead to a Schedule II classification, the presence of Tylenol with Codeine Elixir aligns this combination with the criteria that qualify it for Schedule III. This classification reflects a lower potential for abuse relative to Schedule I and II drugs, as well as a legitimate medical use for pain management.
