Question

Quizplus · Accepted Answer

Drug tolerance occurs when the brain adapts to the presence of drugs by responding less intensely to them, which means that more of the drug is required to achieve the same effects. Habituation refers to a decrease in response to a stimulus after repeated exposure, but it may not necessarily be drug-related. Psychological dependence and withdrawal symptoms are related to addiction and the cessation of drug use.
