What is the primary component of opiates that affects the brain?

The primary component of opiates that affects the brain is endorphins. Opiates, which include drugs derived from the opium poppy such as morphine and heroin, mimic the natural pain-relieving substances in the body known as endorphins. These endorphins bind to opioid receptors in the brain, leading to pain relief, euphoria, and a sense of well-being. This interaction is what makes opiates effective for pain management, but it also contributes to the potential for addiction and misuse, as the brain becomes accustomed to the presence of these substances. Understanding the role endorphins play in both natural pain relief and the action of opiates is crucial for recognizing how these drugs operate in the central nervous system.
