Normally‚ dopamine is then re-uptake back into the transmitting neuron by a specialized protein called the dopamine transporter. If cocaine is present‚ it attaches to the dopamine transporter and blocks the normal recycling process‚ resulting in a buildup of dopamine in the synapse‚ which contributes to the pleasurable effects of cocaine. So patient more of cocaine to bring these affect

Scientist affirm theories that ADHD is caused by the brain not receiving enough Dopamine. Which led to the conclusion that Dopamine transporters were taking up too much of the Dopamine before it could be passed through the brain.

Low levels of serotonin and high levels of dopamine have been associated with aggression in both animals and humans.

The second neurotransmitter is dopamine but the dopamine-aggression link is not as well established as with serotonin. Increases in dopamine activity via amphetamines have been associated with more aggression‚ and antipsychotics reducing dopamine activity have been shown to reduce aggression in violent delinquents. Commentary on serotonin includes evidence from non-human studies. Support
