Master Addiction Counselor Practice Test

The correct answer is five because the Drug Enforcement Administration (DEA) categorizes controlled substances into five distinct schedules. These schedules rank drugs based on their potential for abuse, medical applications, and safety or dependence risk.

Schedule I substances are considered the most dangerous with a high potential for abuse and no recognized medical use, while Schedule V drugs have a lower potential for abuse, are widely accepted for medical use, and are often available without a prescription. This categorization helps regulate the manufacture, distribution, and prescription of these substances to protect public health and safety. Understanding these schedules is fundamental for professionals in addiction counseling, as it informs treatment planning, legal considerations, and the management of client cases involving substance use.
