What are Schedule II drugs characterized by?

Schedule II drugs are characterized by their accepted medical use but also carry a high potential for abuse, which can lead to severe psychological or physical dependence. This classification reflects a balance between acknowledging their medical benefits, such as pain management or treatment of certain medical conditions, and the necessity of strict regulatory controls due to the risks associated with their misuse.

Drugs in this category, such as opioids or certain stimulants, are prescribed with tight restrictions to prevent misuse and ensure they are used appropriately. This is quintessential to managing the risks while allowing access to necessary medications that can significantly improve patients' quality of life when used correctly.

The other options describe characteristics that do not accurately reflect the dual nature of Schedule II drugs. The first option concerning drugs with no medical use is applicable to substances classified in higher schedules, while the third and fourth options suggest a lower level of risk for dependence, which does not align with the classification of Schedule II drugs, known specifically for their potential for addiction.
