Describe how classical conditioning could explain drug tolerance
What will be an ideal response?
The ritual of injecting a drug serves as a conditioned stimulus (CS) that predicts the drug's entering the brain a few seconds later, an unconditioned stimulus (UCS). That stimulus evokes the body's defenses against the drug (unconditioned response, UCR). After suitable repetitions, the injection procedure (CS) may also evoke the body's defenses as a conditioned response (CR). When that happens, the body is starting to combat effects of the drug before the drug even enters the system. The result is less effect of the drug, therefore tolerance.
