Brain Scans Could Replace Breathalyzers In Determining Cannabis-Impaired Drivers, Study Finds

It's no secret that consuming marijuana affects driving skills.

However, accurately proving that a driver is impaired as a result of consumption has been a challenge for toxicologists and researchers for years. The main issue has been that, unlike alcohol, impairment from cannabis cannot be determined by a single measure.

More specifically, the results of a recent study conducted by researchers at the University of Sydney's Lambert Initiative indicated that blood and oral fluid THC concentrations are relatively poor or inconsistent indicators of -induced impairment.

Can Noninvasive Brain Imaging Detect  Impairment?

Perhaps. A new study published in the journal Neuropsychopharmacology has found that cannabis impairment can be detected from according to the brain activity on an individual level, the Harvard Gazette writes.

Known as functional near-infrared spectroscopy (fNIRS), a non-invasive brain imaging procedure, proved to be an objective and reliable way to identify those with performance impaired by THC, the psychoactive ingredient in the plant. The …
