Morphine and other opiates are able to lock into receptor sites for endorphins because they have similar chemical structures. Endorphins are natural painkillers produced by the body and are also associated with feelings of pleasure and reward. Opiates mimic the effects of endorphins by binding to their receptor sites in the brain and other parts of the body, producing pain relief and other effects such as euphoria and sedation.
