Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The proposed research program will investigate the changes in brain chemistry and circuitry that 're-wire' the brain during chronic cocaine use, promote relapse, and complicate treatment efforts. Currently-using and non-treatment-seeking individuals with a cocaine use disorder will undergo a cocaine self-administration paradigm 2-5 days prior to completing positron emission tomography (PET) and functional magnetic resonance imaging (fMRI).
