Question

____________________can refer to the prescribing of one drug of a class to alleviate the withdrawal symptoms of another drug of the same class; can also refer to describe addiction to more than one drug

Answer 1

Psychological and physical dependence are two aspects of drug addiction. Psychological dependence involves emotional need for a drug, while physical dependence results in withdrawal symptoms when drug use is stopped.

Step-by-step explanation:

Psychological dependence refers to the emotional need for a drug to alleviate psychological distress. It is associated with drug craving and can be a significant aspect of addiction. On the other hand, physical dependence occurs when stopping the use of a drug produces physical and/or psychological withdrawal symptoms. In the context of drug addiction, physical dependence can contribute to the need for higher doses of a drug to achieve the same effects (tolerance) and the presence of withdrawal symptoms when drug use is discontinued.
