What schedule includes drugs with a high potential for abuse, such as cocaine and morphine?

The correct choice highlights that Schedule II drugs are categorized as having a high potential for abuse, which may lead to severe psychological or physical dependence. This schedule includes powerful medications such as cocaine and morphine, which are known for their effectiveness in pain relief but also for their abuse potential.

Schedule II drugs are strictly regulated but can be prescribed by healthcare professionals for medical use under controlled conditions. This classification reflects a balance between recognizing the therapeutic benefits of these substances and the risks associated with their potential for addiction and misuse. In contrast, Schedule I drugs are considered to have no accepted medical use and a high potential for abuse, while Schedule III and IV drugs are associated with lower abuse potential and dependency risks.
