Which schedule includes drugs with a high level of abuse potential and no accepted medical use?

The correct answer is Schedule I, which is characterized by drugs that have a high potential for abuse and no accepted medical use in the United States. This classification indicates that these substances do not have any currently accepted therapeutic applications and are considered to be the most dangerous among the drug schedules.

Drugs classified under Schedule I are strictly regulated due to their potential for addiction, severe psychological or physical dependence, and the high risk of overdose. Examples of Schedule I substances include heroin, lysergic acid diethylamide (LSD), and marijuana (under federal law).

Understanding this classification is crucial for professionals in health and substance use treatment, as it guides legal restrictions and influences treatment approaches for individuals who may be using or addicted to such substances. In contrast, schedules II through IV include drugs that may have accepted medical uses but varying levels of risk for abuse and dependence.
