Impairment Science, Inc. is a Cambridge, Massachusetts neuroscience company behind DRUID, a smartphone app that measures cognitive and motor impairment from any cause - cannabis, alcohol, fatigue, medication, or illness - in about one to three minutes. Conceived in 2016 by longtime UMass Boston psychology professor Dr. Michael Milburn and incorporated in 2018, DRUID scores a person's reaction time, decision-making, hand-eye coordination, and balance against their own sober baseline. It is the only impairment technology with three published, peer-reviewed studies validating its accuracy, including research led by Johns Hopkins School of Medicine faculty. The company now sells DRUID Enterprise, a cloud portal that lets employers in construction, mining, EMS, and other safety-critical industries run fitness-for-duty checks without a breathalyzer or urine sample.
