What is an example of a substance that is classified as a narcotic?

Oxycodone is classified as a narcotic because it is a powerful opioid analgesic used for managing severe pain. Narcotics, also known as opioids, interact with specific receptors in the brain to produce pain relief, sedation, and a sense of euphoria. These substances can lead to physical dependence and have a high potential for abuse, which is why they are closely regulated.

In comparison, cocaine is a stimulant rather than a narcotic, impacting the central nervous system in a different way by increasing energy and alertness. Psilocybin, found in certain mushrooms, is classified as a hallucinogen due to its psychoactive effects, which are distinct from the effects of narcotics. Nicotine, commonly associated with tobacco products, is also a stimulant and does not fit into the narcotic category. Thus, oxycodone stands out as the only option that meets the criteria for a narcotic substance.
