Which schedule includes medications like steroids and narcotics with less than 90mg of codeine per dose?

The correct choice pertains to Schedule III drugs, which include certain medications that contain narcotics and other substances with a moderate potential for dependence. Specifically, Schedule III includes medications that have less than 90mg of codeine per dose in combination with other medications. This classification is designed to regulate those substances that are legitimate for medical use but still pose a risk of abuse and dependence, hence requiring a prescription for purchase.

The inclusion of anabolic steroids in Schedule III underlines the regulatory framework addressing their potential for misuse while still allowing for medicinal applications. In contrast to stronger controlled substances classified in Schedule I or II, Schedule III represents a tier where the risk is lower, thus placing certain medications in a more accessible category under medical supervision.
