Amphetamines and cocaine bind to — thus blocking — transporters used for the reuptake of dopamine (and noradrenaline) into presynaptic neurons. This causes the level of dopamine to rise in the synapses. High levels of dopamine in an area of the brain called the nucleus accumbens appear to mediate the pleasurable effects associated with these (as well as other) psychoactive drugs.

I'm still slightly confused...what process is this that cocaine interupts? can anyone maybe give me a reader's digest version? Like, i know that cocaine interupts neurons, but i have no idea if / how it effects the pre or post-synaptics neurons. I just want to get a better general understanding of this. thanx

Also, what is it that actually makes cocaine addictive? Is there a known chemical, or is it just the desire to reach euphoria?
