The state of Wisconsin has submitted a request to the Trump administration, asking that it be allowed to drug test people who apply for Medicaid. That would make this state the first in the nation to do it.  The approach would require able-bodied, childless adults to be screened for drugs when they apply for the health benefits.  If permitted, the drug screening would start in 2019.  Wisconsin Governor Scott Walker amended his original request by not requiring the test if an applicant volunteers to enter a substance abuse treatment program.
