A 38-year-old woman is under investigation following a traffic stop by Corner Brook RCMP.
While there are a variety of roadside tests to detect the presence of THC, there are no tests to check if cannabis levels have resulted in impairment.
Earlier this year, researchers at Massachusetts General Hospital published a study in Neuropsychopharmacology detailing a non-invasive way of determining whether or not THC has resulted in impairment.
Investigators used functional near-infrared spectroscopy (fNIRS), which measures brain patterns, and researchers then correlated this to THC impairment.
In a study of 169 people, researchers found those who had consumed cannabis showed higher levels of neural activity in the prefrontal cortex of the brain when compared to those given a placebo.
“Our research represents a novel direction for impairment testing in the field,” said lead author Jodi Gilman, associate professor at Harvard University and investigator
