What type of drugs are categorized as addictive and sleep-inducing?

Narcotics are drugs that are primarily used for pain relief but also have sedative effects, making them both addictive and sleep-inducing. These substances work on the central nervous system to reduce the perception of pain and can induce feelings of euphoria, which contributes to their potential for addiction. Their impact can lead to severe drowsiness and sedation, as well as a risk of dependency when used over time or inappropriately.

Depressants, while also sleep-inducing, typically refer to a broader category that includes substances like alcohol and benzodiazepines, which do not specifically identify as narcotics. Hallucinogens and stimulants serve different purposes; hallucinogens alter perception and sensation without necessarily inducing sleep, while stimulants increase alertness and wakefulness, opposing the sleep-inducing effect. Thus, narcotics specifically combine the traits of addiction and the ability to induce sleep, making them the correct choice in this context.
