MEPS Drug and Alcohol Testing 4 — Questions and Answers
Question 1: What is the purpose of the 'split sample' procedure in MEPS drug testing?
- To test for a wider range of drugs simultaneously
- To allow the applicant to challenge a positive result using the second portion (Correct answer)
- To reduce laboratory processing costs
- To provide a backup in case the original sample is lost
Correct answer: To allow the applicant to challenge a positive result using the second portion
A split sample divides the specimen into two bottles (A and B), allowing the donor to request retesting of the B bottle at a different certified lab if the A bottle yields a confirmed positive.
Question 2: Which branch of the military has historically had the strictest drug testing waiver policy, making it the hardest to obtain a waiver for a prior positive?
- Army
- Navy
- Marine Corps
- Air Force / Space Force (Correct answer)
Correct answer: Air Force / Space Force
The Air Force and Space Force consistently maintain the most restrictive waiver policies for prior drug use, reflecting their higher security and technical mission requirements.
Question 3: How long can marijuana metabolites (THC-COOH) typically be detected in a chronic heavy user's urine?
- 3–5 days
- 7–10 days
- Up to 30 days or more (Correct answer)
- Exactly 14 days
Correct answer: Up to 30 days or more
In chronic heavy users, fat-soluble THC metabolites can accumulate in body tissue and be detectable in urine for 30 days or more after last use.
Question 4: An applicant discloses use of a prescription opioid (oxycodone) for a past injury. At MEPS, this would most likely be evaluated by:
- The recruiter, who decides eligibility
- The Military Entrance Processing Station physician only
- Both the MRO for the drug test and the MEPS physician for the medical history (Correct answer)
- The Department of Justice
Correct answer: Both the MRO for the drug test and the MEPS physician for the medical history
Prescription opioid disclosure is reviewed by the MRO to validate the drug test result and by the MEPS physician to evaluate whether the underlying medical condition affects military eligibility.
Question 5: Which of the following is NOT one of the five drugs on the standard federal DOT panel tested at MEPS?
- Cocaine metabolites
- Phencyclidine (PCP)
- Benzodiazepines (Correct answer)
- Amphetamines
Correct answer: Benzodiazepines
The standard DOT 5-panel screens for marijuana, cocaine, opiates, PCP, and amphetamines; benzodiazepines are not included unless an expanded military panel is used.
Question 6: Ethyl glucuronide (EtG) testing at MEPS is significant because it can detect alcohol use:
- Only within 6 hours of consumption
- Up to 80 hours after consumption, even after BAC returns to zero (Correct answer)
- Only when BAC exceeds 0.08%
- Only in individuals under age 21
Correct answer: Up to 80 hours after consumption, even after BAC returns to zero
EtG is a direct alcohol metabolite that persists in urine for up to 80 hours, allowing detection of recent alcohol consumption long after standard BAC testing would show zero.
Question 7: A MEPS applicant who is disqualified due to a positive drug test and wishes to reapply should expect:
- Permanent lifetime ban from all military service
- An automatic 12-month waiting period before reapplication in most cases (Correct answer)
- A 30-day waiting period with a recruiter letter of support
- No waiting period; they can reapply immediately with a waiver request
Correct answer: An automatic 12-month waiting period before reapplication in most cases
Most services require approximately 12 months of documented drug-free status before a disqualified applicant can apply for a waiver and reenter the MEPS process.
