most important as it is the only one that is coupled to the respiratory
system

<span>Cocaine is an indirect agonist of dopamine <span>receptors which</span> means he </span>has no specific agonist activity at the dopamine receptor<span> but he enhances his activity. Cocaine</span> acts by binding to the dopamine transporter, blocking the removal of dopamine from the synapse and blocking termination of dopamine signalling. As a result, it increases the extracellular concentration of dopamine and therefore signal to the receiving neurons is amplified.
