Question

question 43
when crack enters the blood stream it quickly attaches to what to create the intense high?
○ blood vessels in the nervous system
○ cells in the lungs
○ none of these
○ dopamine transmitters in the brain

Explanation:

Crack (cocaine) affects the brain's dopamine system. When it enters the bloodstream, it quickly reaches the brain and attaches to dopamine transmitters (specifically, it blocks the reuptake of dopamine, leading to increased dopamine levels and the intense high). Blood vessels in the nervous system aren't the target for the high - inducing action, and cells in the lungs are not involved in creating the high from crack. So the correct option is the one about dopamine transmitters in the brain.

Answer:

dopamine transmitters in the brain
