Which substances are categorized under Schedule III?

Schedule III substances are characterized by their potential for abuse, which is less than that of substances classified in Schedules I and II, but these substances still have recognized medical uses. The correct choice includes anabolic steroids and butalbital, both of which are classified as Schedule III drugs.

Anabolic steroids are synthetic derivatives of testosterone that are often used to promote muscle growth and enhance athletic performance. They are regulated under Schedule III due to their potential for abuse and the health risks associated with their non-medical use.

Butalbital is a barbiturate that is used primarily in combination with other medications to treat tension headaches. Its classification as a Schedule III substance reflects its abuse potential, as barbiturates can lead to physical dependence and withdrawal symptoms when misused.

In comparison, the other options include substances that do not fall under Schedule III. Aspirin and caffeine are generally considered to have low potential for abuse and are not controlled substances. Codeine is classified under Schedule II when dispensed as a single entity medication but can be classified as Schedule III in combination products at low doses. Morphine is a Schedule II controlled substance due to its high potential for abuse. Caffeine and nicotine, while having addictive properties, are not classified as controlled substances under any
