A) cocaine increases the amounts of dopamine, adenosine, and norepinephrine that is released into the synaptic gap between neurons.
B) cocaine blocks the reuptake of dopamine, serotonin, and norepinephrine, which potentiates the effects of these neurotransmitters.
C) there is an increase in the number of dopamine transporters when cocaine is used, and this speeds up the removal of dopamine from the synaptic gap.
D) there is an increase in the number of dopamine and serotonin receptors when cocaine is used, which speeds up the absorption of these neurotransmitters.
