The Warden shall establish programs of urine testing for drug use, to monitor specific groups or individual inmates who are considered as high risk for drug use, such as those involved in community activities, those with a history of drug use, and those inmates specifically suspected of drug use. Testing shall be performed with frequency determined by the Warden on at least 50 percent of those inmates who are involved in community activities. In addition, staff shall randomly sample each institution's inmate population during each month to test for drug use.

(a) Staff of the same sex as the inmate tested shall directly supervise the giving of the urine sample. If an inmate is unwilling to provide a urine sample within two hours of a request for it, staff ordinarily shall file an incident report. No waiting period or extra time need be allowed for an inmate who directly and specifically refuses to provide a urine sample. To eliminate the possibility of diluted or adulterated samples, staff shall keep the inmate under direct visual supervision during this two-hour period, or until a complete sample is furnished. To assist the inmate in giving the sample, staff shall offer the inmate eight ounces of water at the beginning of the two-hour time period. An inmate is presumed to be unwilling if the inmate fails to provide a urine sample within the allotted time period. An inmate may rebut this presumption during the disciplinary process.

(b) Institution staff shall determine whether a justifiable reason exists, (e.g., use of prescribed medication) for any positive urine test result. If the inmate's urine test shows a positive test result for the presence of drugs which cannot be justified, staff shall file an incident report.
