PATIENTS I agree with your editorial. Proponents of marijuana use would have you believe that impairment testing is commercially available and reliable. There is no generally available, evidence-based, accredited, economical impairment test, nor one that can be administered effectively in the Oregon workplace. Law enforcement personnel who are responsible for keeping the roadways free of impaired drivers administer a form of field sobriety testing but not by using some kind of novel "impairment test." Instead they administer a collection of sobriety tests. These tests are time-consuming to perform correctly. If there were a readily available, reliable impairment test for use in addressing workplace substance abuse, it already would have been considered, accepted, validated and put into use on a federal level, but that has yet to happen.
