Question

Quizplus · Accepted Answer

Tolerance refers to the need to increase the amount of a substance to achieve the same effect due to repeated use. Choices A, B, and D illustrate this concept by showing the need for increased doses of a drug, more drug to feel high, and more alcohol to feel a buzz, respectively. Choice C, however, describes a behavioral response (tapping her finger) after smoking, which does not indicate an increased need for the substance to achieve the same physiological or psychological effect, and thus does not exemplify tolerance.
