Narcotics refer to a class of drugs that induce sleep, reduce pain or alleviate anxiety. These substances contain opium or its derivatives and can be taken in various forms such as pills, powders, or tinctures. Examples include morphine, heroin, codeine, and oxycodone. The term "narcotics" is often used interchangeably with the word "drugs," but it specifically refers to those substances that have a sedative effect on the body and mind.
