Withdrawal: reversal of neuroadaptionNeuroadaption

‘Withdrawal’ refers to the physical and mental effects of reducing or ceasing use of a drug when a person has developed a dependence on it.


When regular drug use stops, or is reduced, the body starts to revert to its original state. This can cause ‘withdrawal symptoms’ which last until the body is back in balance (or until use of the drug is resumed). In some circumstances, normal functions can be restored in a few days, but in others complete restoration may take a considerable time, or may never be possible (as with the damage caused by long-time heavy alcohol use).
