Nebraska Probation conducts over 400,000 drug and alcohol tests for youth and adults
annually.
One of those adjustments has been modifying traditional approaches to drug testing to ensure operations continue safely and effectively. For many, this has included increased usage of the sweat patch method, which has allowed for greater social distancing while testing.
Worn on the skin, the sweat patch is a collection device that detects the presence of drug molecules in perspiration and retains evidence of drug use for an extended period. The sweat patch is coated with an outer layer of a polyurethane film and an adhesive that helps keep the patch sealed on the skin for up to two weeks. While the average wear time is seven to ten days, enough sweat can be absorbed into the pad to receive certified laboratory results after just one day. By design, any attempts to tamper with or contaminate the test are usually very noticeable and can be promptly addressed by the supervising officer.
