Substance dependence is diagnosed

Question

Quizplus · Accepted Answer

Substance dependence is diagnosed when there is drug tolerance, which means that the body has adapted to the drug and needs more of it to achieve the same effects. Withdrawal is a common symptom of substance dependence, but it is not necessary for the diagnosis. Psychological dependence, such as craving or feeling like one needs the drug to function, is also a common symptom but not required for the diagnosis. The subjective feeling that it is hard to quit may indicate substance dependence, but it is not enough to make the diagnosis. Therefore, choice C is the best answer.
