Which group of substances includes barbiturates and benzodiazepines?

CNS stimulants
CNS depressants
Hallucinogens
Antidepressants

The correct answer is: CNS depressants

The group of substances that includes barbiturates and benzodiazepines is classified as CNS depressants. These substances primarily act on the central nervous system to produce a calming effect, reduce anxiety, and promote sedation. Barbiturates are a class of medications that are effective as sedatives and anesthetics, whereas benzodiazepines are commonly prescribed for their anxiolytic (anxiety-reducing) effects and are also used for sleep disorders. Both types of drugs enhance the effect of the neurotransmitter gamma-aminobutyric acid (GABA), leading to increased inhibition in the brain, which results in relaxation, drowsiness, and decreased motor skills. This depression of the CNS can be beneficial for treating various medical conditions, but it also carries the risk of addiction and overdose, especially when combined with other depressants like alcohol. Understanding these classifications helps in making informed decisions in counseling and treatment planning, particularly for individuals who may be at risk of substance misuse.
