Final answer:
The statement is true; a drug with medical use and high abuse potential would be listed as a Schedule II substance. Psychoactive drugs are substances that alter mental states and can be legally prescribed for medical use or abused. Anxiolytics are one type of psychoactive drug that can be legally prescribed.
Step-by-step explanation:
A drug that has an approved medical use but also has a high potential for abuse would indeed be listed as a Schedule II substance. According to the Controlled Substances Act in the United States, Schedule II drugs are defined by their legitimate medical use alongside a high potential for abuse which may lead to psychological or physical dependence. An example of such a drug is oxycodone, a potent opioid used for pain management.
Psychoactive drugs are substances that affect the brain and alter consciousness, mood, or thoughts. Examples include caffeine and cannabis. Drug abuse occurs when a substance is used in a manner or dosage other than prescribed; drug addiction can occur with the continued use of the drug despite adverse consequences. Opioids, cannabinoids, and benzodiazepines are three classes of psychoactive drugs that contain compounds with high abuse potential.
Anxiolytics, such as benzodiazepines, may be prescribed by a physician to help manage anxiety. These drugs, including diazepam and alprazolam, facilitate the action of GABA, a neurotransmitter that generally contributes to a depressant effect on the nervous system, which can help in reducing anxiety symptoms.
