In keeping with the compensatory-response model of conditioning, many drug fatalities occur when the addict injects a(n) dosage of the drug in a setting that is to drug use.

In keeping with the compensatory-response model of conditioning, many drug fatalities occur when the addict injects a normal dosage of the drug in a setting that is unrelated to drug use.

Explanation:

Pavlovian conditioning supports the idea that for each stimulus there is a response (conditioned and unconditioned). In this case, such responses serve to mitigate the negative effects of the substances. The unconditioned response, as depicted in the figure, is the source of the unconditioned stimulus. However, the conditioned compensatory response is a "reflection" of the association between the two types of stimuli. These conditioned compensatory responses mediate the development of tolerance by counteracting the effect of drugs. In this case, according to compensatory responses, many fatalities occur when the addict injects a normal dose of the drug into an environment unrelated to drug use.
