JAMA Network Open has published the results of a study on fatal two-car crashes and the potential role that opioid use is playing in them. Opioid users in Oregon can probably see how the use of the prescription drug and driving do not go together. Opioids cause drowsiness and impair cognition and motor skills. As for those who take opioids for chronic pain, they may develop a tolerance for them, and so it can be hard to say if the drugs contribute to a crash.
