Topic 2.5
What alternative explanation may challenge the widely accepted theory that cocaine's addictive nature derives primarily from its ability to block dopamine reuptake?
The addictiveness of cocaine comes from its impact on glutamate transmission rather than blocking dopamine uptake alone.
Cocaine enhances GABA receptors contributing more towards its addictive properties than dopamine reuptake blocking.
Cocaine's addictive qualities might be due not only to dopamine reuptake inhibition but also its influence on stress hormones like cortisol affecting reward circuits.
Cocaine increases serotonin levels which makes it more addictive than just blocking dopamine reuptake.
