When heroin is taken, it binds to opioid receptors in the brain, mimicking the effects of natural endorphins, which are neurotransmitters that help relieve pain and induce feelings of pleasure. This leads to an increased release of dopamine, resulting in intense euphoria and pain relief. As the body adjusts to the presence of heroin, it may reduce its natural endorphin production, leading to dependence and withdrawal symptoms when heroin is not available. Over time, this can alter the brain's chemistry and function.
