What type of dependency can Schedule II drugs cause?

Schedule II drugs are classified under the Controlled Substances Act due to their high potential for abuse and the severe psychological and physical dependence that can result from their use. These substances are recognized for their medical use but also come with a significant risk of developing both psychological and physical addiction.

Psychological dependence refers to the emotional or mental attachment to a drug, while physical dependence involves the body's adaptation to a substance, leading to withdrawal symptoms when it is not available. The nature of Schedule II drugs, including opioids and some stimulants, makes them especially susceptible to creating this severe level of dependence among users.

Other options suggest lower levels of dependency or focus on specific populations (like children), which do not accurately describe the risks associated with Schedule II medications. Therefore, the characteristics of these drugs affirm that they can indeed lead to severe psychological or physical dependence in individuals using them.
