how do drug addictions negatively affect your pleasure pathway?
increase dopamine levels help you care more about family and friends
dopamine improves neural communication in the pleasure pathway
the pleasure pathway is now able to make you feel better about yourself
too much dopamine burns out dopamine receptors, you need more of the drug to get the same high

Explanation:

Drug addiction affects the pleasure pathway. When drugs are used, they cause a large release of dopamine. Over - time, too much dopamine can lead to a decrease in the sensitivity of dopamine receptors (burning out). As a result, the individual needs more of the drug to achieve the same level of "high" (euphoria). The first three options are incorrect. Increasing dopamine levels due to drug addiction does not make one care more about family and friends. Dopamine in the context of drug addiction disrupts normal neural communication rather than improving it in a healthy sense. And the "feeling better about oneself" in a drug - induced state is a false and harmful perception, not a positive and healthy function of the pleasure pathway.

Answer:

Too much dopamine burns out dopamine receptors, you need more of the drug to get the same high.
