A narcotic is a type of drug that is used for pain relief and typically has sedative and potentially addictive properties. The term “narcotic” originally referred to a substance that numbs or deadens sensation, but has come to encompass a range of drugs, both natural and synthetic, that have pain-relieving effects. Narcotics are often classified as opioids, which are drugs that act on the central nervous system to reduce the perception of pain. Examples of commonly used opioids include morphine, fentanyl, and hydrocodone. While these drugs can be effective in treating pain, they also have a high potential for abuse and addiction, and can cause serious side effects, including respiratory depression and overdose. It is important to use narcotics only as directed by a healthcare provider and under close medical supervision.
