What type of substances does Schedule V include?

Schedule V substances are classified as drugs that have a lower potential for abuse relative to substances in higher schedules, such as Schedule I through IV. These substances generally have accepted medical uses and consist of specific mixtures that are recognized for their therapeutic effects.

One of the hallmark features of Schedule V substances is that they include medications that contain minimal amounts of certain narcotics. This classification specifically encompasses preparations such as mixtures that contain small quantities of codeine or opium, commonly found in cough syrups and medications designed to alleviate pain or cough while minimizing the potential for addiction and misuse.

In contrast, the other categories outlined in the options - highly addictive drugs, stimulants, and hallucinogens - would typically be classified under higher schedules that indicate a greater potential for abuse and fewer accepted medical uses. Therefore, the correct identification of Schedule V focuses specifically on its inclusion of mixtures with small amounts of codeine or opium.
