Detection of ฮ”9-Tetrahydrocannabinol Impairment Using Resting-State Functional Near-Infrared Spectroscopy: A Randomized Clinical Trial.

A randomized trial found that functional near-infrared spectroscopy (fNIRS) accurately detected THC impairment with superior performance compared to traditional field sobriety tests. This neuroimaging approach offers an objective method for impairment detection that could transform cannabis safety protocols, though practical implementation challenges remain.
