Answer 1

Depressants have a relaxing effect on the central nervous system, are often used as sedatives, and can be addictive if taken in large doses.

Step-by-step explanation:

Depressants are a type of psychoactive drug that have a relaxing effect on the central nervous system. They calm the brain, reduce anxious feelings, and induce sleepiness. Depressants are often prescribed as sedatives and can be addictive if taken in large doses.

Examples of depressants include barbiturates, benzodiazepines, and tranquilizers. These drugs work by acting as agonists of the gamma-Aminobutyric acid (GABA) neurotransmitter system, which has a quieting effect on the brain. They are commonly used to treat anxiety and insomnia.

It's important to note that while depressants can have therapeutic effects, their abuse potential is relatively high. Repeated use can lead to physical dependence and tolerance, and psychological dependence is also possible.
