23. Neurobiology of Addiction :
• Although abuse drugs have different initial targets and
actions, the resultant addictions share several key features
owing to common effects on crucial neural circuits.
• The release and/or increase in dopamine levels in crucial
brain regions particularly the nucleus accumbens and in
related regions of the mesolimbic mesocortical
dopaminergic system are important for reinforcing effects
of cocaine and other drugs of abuse, from alcohol and
opiates to nicotine and cannabis.
• For example,Cocaine acts by blocking the presynaptic
transporter for dopamine, also the presynaptic transporters
for serotonin and noradrenaline, thereby flooding the
synapse with dopamine, serotonin and noradrenaline.

system, neocortex and brainstem.
