Compensatory Responses It was observed that some people mysteriously died of a drug overdose. The reasons that it appeared mysterious is that (a) They were experienced drug users (b) They does of drug that they overdosed on, was not that different from what they were usually taking. However, it was discovered that many of these overdoses occurred in a location that the drug user normally did not take the drug (e.g. actor River Phoenix). Why would the location of where a person takes the drug make a difference?

Compensatory Responses Your body tries to maintain a delicate balance of biological functioning or homeostasis. For example,

• If we are thirsty, we drink • If we are hungry, we eat • If we are tired, we sleep Likewise, • if we take a stimulant, our body slows down • if we take a depressant, our body is stimulated

Compensatory Responses Compensatory responses:

The body usually tries to maintain a state of homeostasis. When people use drugs, the body and brain attempts to counteract the effects of the drug and produces reactions that are opposite to that of the drug.

Compensatory responses can help explain drug tolerance, withdrawal effects and cravings for a drug. Tolerance:

Decreased responsivity to a drug (usually you need to increase the dosage to get the same effects)

Withdrawal:

The experience of strong reactions opposite to those produced by the drug The withdrawal symptoms may be thought of the body’s compensating response still becoming active in the absence of the drug.
