Abstract

Single photon emission tomography (SPECT) is the prototypical tool for measuring cerebral blood flow (CBF) in discrete areas of the brain. Compared with when a male ‘crack’ cocaine user received placebo, oral cocaine (1mg/kg) ingestion was associated with non-uniformity of overall CBF with hypoperfusion of discrete brain regions, particularly of the frontal, temporo-parietal, basal ganglia, and thalamic areas. While these results should be viewed as preliminary, they do suggest that oral cocaine use may be associated with CBF abnormalities in ‘crack’ users.
