HOSA Pharmacology Assessment Practice Test

The schedule of controlled substances with the lowest abuse potential is Schedule V. Substances classified under Schedule V are considered to have a lower risk of dependence and abuse compared to those in higher schedules. These substances typically have accepted medical uses and may include medications that contain small amounts of narcotics or other controlled substances. Examples often include cough preparations with less than 200 milligrams of codeine per 100 milliliters or per 100 grams, promoting their medicinal value while limiting potential for misuse.

In contrast, substances in higher schedules like Schedule I, II, and IV have a greater potential for abuse and dependency. Schedule I substances are deemed to have no accepted medical use in the United States, making them highly restricted. Schedule II substances, while having accepted medical uses, possess a high potential for abuse, necessitating strict regulations. Schedule IV substances have more potential for abuse than Schedule V but less than Schedule II, placing them in a moderately regulated category. Understanding the classification systems aids in recognizing the varying levels of regulatory control and potential risks associated with different controlled substances.
