A drug test only happens when an officer already has a reason. Impairment Risk flags likely impairment from normal use of the platform, and three in four high flags that get tested come back positive.
Drug testing in community supervision is reactive by design. An officer orders a test on suspicion or on schedule, the result comes back, and a positive triggers a response. By then the person may have relapsed several times, missed contacts, or done something dangerous. And a test only finds the substances the panel was built to find.
Impairment Risk uses signals from normal use of the RePath platform to flag when a participant is likely impaired. No cup, no swab, no lab, and no extra work for the officer or the participant. The officer gets a low, medium, or high risk level and decides what to do with it: a check-in, a test, a call to a parent, a conversation.
It does not prove the cause. It does not replace testing. It directs testing toward the moments a test is most likely to matter, which is a different job from telling an officer what a person took.
When Impairment Risk flags someone as high risk and they get tested, three in four come back positive. That is how often a flag is right. The companion number is how much it catches: four in five impairment events that a drug test later confirms. Both are measured across every agency we work with, not a pilot, and the catch rate only counts events a test could confirm. Substances no panel screens for are not in that denominator, which makes four in five a floor.
A number in the nineties would invite the obvious question of why an agency still needs a testing program. Three in four flags earning a test is a large improvement on testing at random, and it leaves the testing program intact.
A Missouri treatment court director had a participant approved for one diet pill a day. Impairment Risk flagged her, and it turned out she was taking more. The same court had a participant huffing compressed-air dusters, which no drug test can catch; the flag named the day. A third participant kept passing her UAs while misusing a prescription the court had to honor. The flag sent the director to the house, where she found twelve medications. Now the pills get counted at every meeting.
"RePath gives us a tool to step in faster because we can see what is going on with them."
In a Missouri juvenile circuit, Impairment Risk flagged a youth nobody suspected of using. The test showed exposure, not use. Two weeks later an explosion at the house revealed meth on the premises. He had been living in it, and the flag led to a child welfare referral instead of a violation. A different officer in the same circuit started testing whenever the flag went high; every test came back positive.
A court services director in Alabama got her first possible-impairment alert the weekend after training. It was accurate: a participant whose medication had just changed, at home and in bed. It ended with a conversation and a doctor's visit, not a violation. That is the point of a flag that arrives early.
