Which substance is primarily known for inducing drowsiness?

• A. Stimulants
• B. Depressants
• C. Hallucinogens
• D. Inhalants

Answer: (B)

The substance primarily known for inducing drowsiness is depressants. Depressants work by slowing down the central nervous system, which can lead to calming effects and reduced anxiety but also increases the likelihood of drowsiness and sedation. Common examples of depressants include alcohol, benzodiazepines, and barbiturates, all of which can significantly impair cognitive functions and promote sleepiness. Stimulants, in contrast, increase alertness and energy levels, leading to a state of wakefulness rather than drowsiness. Hallucinogens can alter perception and mood but do not primarily induce drowsiness as their main effect. Inhalants can have varied effects depending on the substance and method of use but are often not classified solely as substances that induce drowsiness. Therefore, depressants are the most accurate choice for this characteristic of inducing drowsiness.
