Why does the Department of the Interior handle drug testing?
The U.S. Department of the Interior's mission is to protect America's natural resources and heritage, honor our cultures and tribal communities, and supply the energy to power our future.  To learn more about DOI visit The Interior Business Center, within the Department, supports the Offices and Bureaus within the Department, as well as federal agencies outside the Department, as a Shared Service Center. Drug and alcohol testing are one of the many services Interior Business Center offers.

How can Interior Business Center help my agency run the Drug-Free Workplace Program?
The Interior Business Center staff can manage or assist with every facet of the Drug-Free Workplace Program at your agency, from program management to the urine collections.

How do we get started?
Contact the Interior Business Center Drug & Alcohol Testing Staff today at or 202-208-5638. Helpful information to have available includes how many Testing Designated Positions (TDPs) your agency or office has, how many donors you test annually, what geographic locations your donors/employees are in, what services you are interested in using.

Who are your vendors/contractors?
Currently, Pembrooke Occupational Health and Quest Diagnostics. Pembrooke is responsible for scheduling tests, sending supplies to clinics, maintaining the web based database system, and providing the Medical Review Officer function. Quest analyzes the urine specimens. See our Contracts & IAAs page for more information.

Can Interior Business Center Drug & Alcohol Testing staff provide services to non-federal entities?
No, at this time we cannot provide services to state governments, private organizations, or non-federal organizations.

I am a supervisor at DOI and have a suspicion that one of my employees is using drugs. What should I do?
Immediately contact the DOI Drug Program Manager at 202-208-5638.

I am a DOI employee chosen for random testing. Why me?
The Drug-Free Workplace Program at DOI was not created to single out individual employees. As an employee in a Testing Designated Position (TDP) you have agreed to submit to random testing. Testing at DOI is done several times a year and employees have the same odds of being tested each time a random selection is made (e.g. if you are tested in October, that does not mean you cannot be tested again in November, your name is not "set-aside" so to speak). DOI tests 15% of employees in Health and Human Services (HHS) positions (Presidential Appointees, Top Secret Clearance holders, employees involved in the suppression of fires, law enforcement personnel, dive team members, medical personnel, lifeguards, search and rescue personnel, explosives handlers, pressurized container operators). DOI tests 50% of employees in Department of Transportation (DOT) positions (motor vehicle operators, boat operators, train operators, airplane operators). You may be chosen several times in a year to take a test or not at all.

I am a DOI supervisor and my employee is not in one of the positions mentioned above but was asked to take a random test, should they still be tested?
Contact your servicing personnel office. Most likely, the employee was miscoded in the Human Resources system as occupying a TDP.

I am a supervisor at an outside agency and have a suspicion that one of my employees is using drugs. What should I do?
Contact your agency's Drug Program Coordinator immediately.

I am a donor who has been told to report to a collection site for a drug test, what can I expect?
Bring a photo id and be ready to provide a urine specimen. Under federal regulations, the collection site cannot accept other specimen types (hair, blood, saliva). You must provide a urine specimen. You will need to provide or verify the last five digits of your Social Security Number or other employee identification number. You do not need to bring prescription medicine or doctor notes/orders with you to the clinic. If medical/prescription information is needed after your urine has been analyzed, you will be contacted. You will be asked to empty your pockets, remove outer clothing (jackets or hats), and wash your hands. You will be allowed to provide the specimen in privacy. You should have visual contact of your specimen at all times until it is sealed with the tamper evident seals. You will read the certification statement on your Custody and Control Form, sign your name, and provide your contact information. You will receive a copy of your Custody and Control Form.

What drugs will I be tested for?
Those allowed per federal regulations, marijuana, cocaine, PCP, opiates, and amphetamines.

I am on a prescription for an amphetamine. Will I come up positive?
Possibly. The Drug-Free Workplace Program was created to identify illegal drug users not those with legitimate prescriptions. If your specimen meets the cut-off levels for amphetamines, your contact information will be shared with the Medical Review Officer (MRO) and they will contact you to discuss. Once the MRO determines you are on a legitimate prescription, your results will be reported to the Agency as negative.

I live in a state that allows the medicinal use of marijuana. If I have a prescription for marijuana, will I come up positive?
Although your state recognizes the medicinal use of marijuana, the federal government does not. Using marijuana while employed for the federal government is prohibited.
