If 10 tablets of Tylenol No. 3 are crushed and added to 100 ml of distilled water, how should the resultant mixture be classified?

The mixture resulting from crushing 10 tablets of Tylenol No. 3 and adding it to 100 ml of distilled water is classified as a C3 substance. Tylenol No. 3 contains codeine, which is an opioid and is classified as a Schedule III controlled substance under the Controlled Substances Act.

In this scenario, the act of crushing the tablets does not change the classification of the active ingredient itself, which is the key element in determining the schedule. Schedule III drugs generally have a lower potential for abuse compared to Schedule II drugs and are used for medical purposes.

The classification remains consistent irrespective of the form it is in as long as the chemical composition does not change. Therefore, the resultant mixture retains its classification as a Schedule III substance. This is a fundamental aspect of the pharmaceutical regulations that relate to controlled substances.
