"Impairment and Dysfunction
Cocaine users display a marked reduction in VMAT2 immunoreactivity. Suffers of cocaine-induced mood disorders displayed a significant loss of VMAT2 immunoreactivity, this might reflect damage to striatal dopamine fibers. These neuronal changes could play a role in causing disordered mood and motivational processes in more severely addicted users."
How many of you atheists were theists before you started using cocaine? Ever wondered if your change was less to do with 'seeing the light' and more to do with you damaging the ability to do so.
