Final answer:
Controlled substances are classified into different schedules under federal and state statutes, based on abuse potential, dependency risk, and medical utility. These schedules range from Schedule I (high abuse potential, no accepted medical use) to Schedule V (lower potential for abuse, accepted medical uses).
Step-by-step explanation:
The question pertains to how controlled substances are categorized for legal purposes. In the United States, federal and state statutes classify controlled substances into different schedules based on factors such as their potential for abuse, risk of dependence, and medical utility. These classifications range from Schedule I, which includes substances considered to have a high potential for abuse and no accepted medical use, to Schedule V, which includes substances with a lower potential for abuse and accepted medical uses.
While the information provided about FDA regulations of food is relevant to how substances are regulated, the classification of controlled substances specifically refers to drugs and chemicals that are regulated under the Controlled Substances Act due to their potential for abuse or dependency, rather than general FDA food standards.
