Quizplus · Accepted Answer

The need for higher dosages of a drug to achieve the desired effect is known as tolerance. This is a common symptom of drug dependence and addiction. As the body becomes accustomed to the drug, it requires larger doses to achieve the same high. Potentiation refers to the increased effects of a drug when multiple drugs are used together. Dependency occurs when a person relies on a drug to function normally, and addiction involves the compulsive use of a drug despite negative consequences.
