Quizplus · Accepted Answer

Tolerance is the phenomenon where an individual requires increasing amounts of a drug to achieve the desired effect. This is a common occurrence with cocaine use, as the brain adapts to the presence of the drug and requires more to achieve the same high. Withdrawal, psychological addiction, and drug dependence are related to drug use but not specifically to the phenomenon of tolerance.
