Arlington Police report a crash at Mystic Valley Parkway and River Street around 1 p.m. today was the result of the driver nodding off on an opioid.
Police say an initial dose of Narcan did not revive the unconscious, not breathing driver and that they broke out a portable defibrillator and were starting CPR when a second dose of Narcan revived the man, a 32-year-old Arlington resident. He was then transported to a Boston hospital for care.
According to police:
An investigation indicates that the driver came over the Harvard Avenue bridge while driving into Arlington from West Medford when he lost consciousness, put his car into reverse, and crashed into a vehicle that was driving behind him.
The driver of that car was not injured, police say.
