Researchers report brain-based method to determine impairment from cannabis intoxication

Researchers at Massachusetts General Hospital (MGH) have found a noninvasive brain imaging procedure to be an objective and reliable way to identify individuals whose performance has been impaired by THC, the psychoactive ingredient in cannabis. The technique uses imaging technology known as functional near-infrared spectroscopy (fNIRS) to measure brain activation patterns that correlate to impairment from THC intoxication. As reported in the journal Neuropsychopharmacology, the procedure could have significant implications for improving highway and workplace safety.
