Final answer:
Prozac is a psychoactive drug that can be prescribed and anxiolytics might be prescribed by a physician to manage anxiety. Psychoactive drugs include opioids and are not all illegal or by prescription only; alcohol and nicotine are legal examples. Drugs like benzodiazepines and barbiturates activate GABA receptors, having a depressant effect.
Step-by-step explanation:
Psychoactive drugs are substances that, when taken, can alter a person's mood, perception, thinking, or behavior. These substances can sometimes lead to addiction and have both legal and illegal forms in society.
Anxiolytics and other medications such as Prozac, which is indeed a psychoactive drug, are often prescribed by physicians to help with mental health conditions. Prozac works as an antidepressant and belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs).
There are three main classes of psychoactive drugs that include opioids: narcotics, central nervous system (CNS) depressants, and CNS stimulants. While opioids are usually prescription medications, they can also be misused and taken illegally.
It is False to say that all psychoactive drugs are either illegal or available by prescription only. Some psychoactive substances like alcohol and nicotine are legally available without a prescription.
Anxiolytics, which might be prescribed by physicians to help manage anxiety, generally act on receptors for the neurotransmitter GABA. Two drugs that activate GABA receptors are benzodiazepines and barbiturates. They have a depressant effect because they enhance the action of GABA, which is an inhibitory neurotransmitter, contributing to a decrease in nervous system activity.
