Endorphins, the natural chemical in your brain that produces pain relief. It also effects the dopamine levels of the brain, which control how happy and euphoric you feel. If you take enough opiates over a long period of time, the brain stops naturally producing these two chemicals, because it gets used to the boost the opiates given to it. That's why it's so difficult to come off of opiates. You feel depressed and in pain, because your brain is not used to producing these chemicals on their own anymore. It takes time for the brain to heal and to eventually produce these chemicals normally again.

Most opiates are agonists of the mu opiod receptors. These are found both in the brain and in the gut. When they activate the receptors in the gut, it causes paralysis of the intestines and slows down peristalsis.
