Dopamine and addiction. Cocaine and amphetamines inhibit the re-uptake of dopamine. Cocaine is a dopamine transporter blocker that competitively inhibits dopamine uptake to increase the presence of dopamine. Amphetamine increases the concentration of dopamine in the synaptic gap, but by a different mechanism.opamine helps in focus and attention.
