What type of drug is heroin classified as?

Heroin is classified as an opioid depressant because it is derived from morphine, which is a natural alkaloid of the opium poppy. Opioids interact with specific receptors in the brain to produce effects such as pain relief, sedation, and feelings of euphoria. As a depressant, heroin slows down the central nervous system, which can result in decreased heart rate, respiratory depression, and decreased mental alertness. This classification is important in understanding the drug's potential for addiction and the serious health risks associated with its use. Understanding heroin's effects as an opioid depressant underscores the importance of addressing its use and related issues in law enforcement and public health.
