The withdrawal from various opioid medications, including morphine, causes similar effects, most of which is caused by stimulation and over-stimulation of the central nervous system. [9] [7] The effects of morphine withdrawal can range from gastrointestinal disturbances to symptoms like tremors (involuntary shaking, most commonly in hands ...
“The brain changes, and it doesn’t recover when you just stop the drug because the brain has been actually changed,” Kreek explained. “The brain may get OK with time in some persons. But it’s hard to find a person who has completely normal brain function after a long cycle of opiate addiction, not without specific medication treatment.”

One form of behavioral neuropharmacology focuses on the study of drug dependence and how drug addiction affects the human mind. Most research has shown that the major part of the brain that reinforces addiction through neurochemical reward is the nucleus accumbens. The image to the right shows how dopamine is projected into this area.
In psychopharmacology, researchers are interested in any substance that crosses the blood–brain barrier and thus has an effect on behavior, mood, or cognition. Drugs are researched for their physiochemical properties, physical side effects, and psychological side effects.
Addiction is a brain disorder characterized by compulsive drug use despite adverse consequences. [ 36 ] [ 56 ] [ 57 ] [ 58 ] Addiction involves the overstimulation of the brain's mesocorticolimbic reward circuit ( reward system ), essential for motivating behaviors linked to survival and reproductive fitness, like seeking food and sex.
