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

The category that includes drugs with a high level of abuse potential and no accepted medical use is Schedule I. Schedule I substances are considered to have a high potential for addiction and are deemed unsafe to use even under medical supervision. This classification reflects the strict controls and legal restrictions placed on these substances, as they are viewed as having no therapeutic benefit.

Drugs in this category often include substances like heroin, LSD, and marijuana (in many jurisdictions). Since they are associated with a significant risk of physical or psychological dependence, they are not available for prescription or medical use. Understanding the classification of substances is crucial for professionals in the field, as it guides treatment approaches, legal ramifications, and prevention efforts related to substance use disorders.
