Does the Immigration Medical Exam Include a Drug Test?
No. The immigration medical exam does not include a routine drug screen, and nothing in the standard lab panel tests for drugs. The civil surgeon does, however, ask about drug use as part of the medical history and is required to assess it and record findings accurately. That distinction matters, so this guide covers both what is tested and what is asked.
What is actually tested
The required tests on the immigration medical exam (also called the green card medical exam) are set by CDC’s Technical Instructions for civil surgeons, and they depend on your age:
| Test | Who gets it | Sample |
|---|---|---|
| Tuberculosis (IGRA) | Everyone 2 years and older | Blood |
| Syphilis | Ages 18 to 44 | Blood |
| Gonorrhea | Ages 18 to 24 | Urine |
Outside those age ranges, syphilis and gonorrhea testing is done only if there is a reason to suspect infection. HIV is not tested. None of these is a drug test, including the urine sample, which is analyzed for gonorrhea only. A positive TB result has its own next steps, explained in our guide to what happens after a positive TB test.
What the civil surgeon does assess
Drug abuse and drug addiction are one of the health-related grounds CDC asks civil surgeons to evaluate. In practice, that assessment is based on:
- Your medical history. You’ll be asked about current and past use of drugs and other substances, including medications.
- The physical exam. The surgeon looks for physical signs relevant to substance use, alongside the rest of the exam.
- A brief mental status evaluation. This is routine for every applicant.
- Records you provide. Treatment or other documentation you bring is part of the picture.
The civil surgeon applies CDC’s definitions to decide how to record what they find. Those definitions are specific, and they consider things like the substance, the pattern of use, and how recently it occurred. If something in your history needs more evaluation, the surgeon may ask more questions or refer you for further assessment before completing the form.
What the civil surgeon does not do is decide your immigration case. They document your medical situation; USCIS makes decisions. For how the other health-related grounds work, see our guide to health conditions and the exam.
Why accurate answers matter
The form you receive is a medical record prepared under federal instructions, and it goes into your immigration file. Inaccurate or incomplete information can create problems of its own, separate from whatever the underlying history is. Inconsistencies between what you tell the civil surgeon and what appears elsewhere in your file can also raise questions later.
We never coach answers, and you should be cautious about any provider who offers to tell you what to say. The right preparation is to understand your own situation before you walk in, and for anything with legal implications, that means an attorney.
Marijuana: federal law is what counts here
This is the question applicants ask most, and it is where state and federal law part ways. Many states have legalized marijuana for medical or adult use. Immigration law is federal, and under federal law marijuana is still a controlled substance. State legalization, a state medical card, or legal purchase at a licensed dispensary does not change how federal immigration law treats it.
That can have consequences beyond the medical exam, because questions about controlled substances also come up in the legal parts of an immigration case. We won’t give legal advice, and this page isn’t legal advice. If you use or have used marijuana, or work in the cannabis industry, speak with an immigration attorney before your appointment, not after. Your attorney can explain how your specific history fits the rules and what to expect.
Prescription medications are fine
Taking medication as your doctor prescribed it is medical treatment. That includes controlled prescriptions such as stimulants for ADHD, benzodiazepines, sleep medications and prescribed pain relievers.
Bring a list of everything you take: the medication name, dose, how often, and the prescribing doctor. Pharmacy printouts or photos of the labels work well. A clear list lets the civil surgeon record your medications accurately and avoids confusion. If you have used a prescription medication in a way other than prescribed, that is a history question to discuss with your attorney first.
If you’re in recovery
A history of substance use that you’ve addressed is not something to hide from the surgeon. Bring documentation of any treatment program, the dates, and a letter from your treating provider if you have one. CDC’s instructions account for remission, and records help the surgeon apply them correctly. How your history affects your case legally is, again, a question for your attorney.
Before your appointment
- Talk to an immigration attorney first if you have any drug-related history or concern.
- Make a complete medication list.
- Gather treatment or recovery records if they apply.
- Answer the surgeon’s questions accurately.

Frequently asked questions
Is the urine sample at the immigration medical exam a drug test?
No. For applicants aged 18 to 24, the urine sample is used for the required gonorrhea test, a lab test that looks for that infection only. It is not a drug screen. Outside that age range, a urine sample isn't part of the required panel. The routine blood tests are the TB blood test for ages 2 and older and the syphilis test for ages 18 to 44.
Should I tell the civil surgeon that I use marijuana?
We can't tell you what to say, and no clinic should. What we can tell you is that the civil surgeon is required to ask about drug use and record the answers accurately, and that marijuana is treated under federal law, which applies to immigration, differently than under many state laws. Because answers can have legal consequences, speak with an immigration attorney before your appointment so you understand your situation first.
Will my prescription medications cause a problem?
Taking medication as prescribed by your doctor is medical treatment, not drug abuse. Bring a list of everything you take, with the name, dose and prescribing doctor, including controlled medications such as ADHD stimulants, anxiety medications or prescribed pain relievers. A clear, documented list helps the civil surgeon record your history accurately. Using a prescription drug in a way it wasn't prescribed is a different matter, and your attorney is the right person to ask about it.
Does alcohol use come up on the immigration medical exam?
It can. Alcohol is not a controlled substance, so it isn't assessed the same way as drug use. But alcohol use connected to harmful behavior, such as driving under the influence, can be considered under the separate physical or mental disorder ground, and the civil surgeon may ask about it. As with drug history, accurate answers matter, and questions about how a past incident affects your case belong with an immigration attorney.
