Getting Your License Back After Drug Use: Tests, Medical Exam, and Self-Check

After a suspension related to drugs, waiting for the sanction to end is not always enough to resume driving. The recovery of the license depends on the medical examination, the required documents, and the procedure carried out with the ANTS.

Start by reading the decision and the prefecture’s instructions

The procedures vary depending on the nature of the measure, its duration, and the department. The notification letter and the prefecture’s website indicate the required tests, the competent commission, and the deadlines to be respected.

Service-Public specifies that in case of an administrative suspension longer than one month, a medical examination is necessary to recover the license. When the suspension reaches six months or more, a psychotechnical test must be completed before the medical examination.

Medical commission or approved doctor?

For an offense related to alcohol or drugs, the appointment is made with the competent medical commission, usually via the prefecture’s website. For other offenses, the examination may be conducted by an approved doctor.

The examination focuses on physical, cognitive, and sensory fitness to drive. Doctors may request additional tests when necessary.

Biological tests are not the same in all cases. Service-Public asks to bring their results when they are mentioned in the notification letter. The instructions received for your file therefore take precedence over lists found online.

Why might a urine test be requested?

Urine allows the detection of metabolites of certain substances over a window often longer than saliva. For cannabis, the commonly searched marker is THC-COOH.

Depending on the laboratory and the prescription, the analysis may cover cannabis alone or several families: cocaine, amphetamines, methamphetamines, MDMA, opiates, or other substances.

What thresholds are found in rapid tests?

Commercially available urine tests have their own thresholds. Frequently used values are 50 ng/mL for THC-COOH, 300 ng/mL for cocaine or opiates, and 1,000 ng/mL for amphetamines or methamphetamines. These values should not be presented as mandatory thresholds for all prefectures or laboratories.

A self-test is not the official analysis. A laboratory may use a different method, threshold, or confirmation. Only the result requested in your file is accepted by the administration.

What is the purpose of a three-threshold THC test?

The Drugdiag® 3THC urine test detects THC-COOH at 20, 50, and 150 ng/mL. It can help monitor the evolution of a positive result during a personal process, but it does not allow predicting with certainty the date of a negative laboratory result.

How long does cannabis remain detectable in urine?

The duration varies greatly depending on frequency of use, quantity, metabolism, product composition, and test threshold. In a regular user, THC-COOH can remain detectable long after the effects have disappeared.

There is no “detox” method that guarantees a quick negative result. Excessive dilution, substitution, or products claiming to mask consumption are risky and can make a sample unusable.

Practical steps

  1. read the suspension decision and prefecture instructions;
  2. make an appointment without waiting for the last days of the suspension;
  3. complete psychotechnical tests when required;
  4. perform the requested biological tests within the indicated deadline;
  5. prepare the medical form, identity, and administrative decisions;
  6. after a favorable opinion, apply for the license online on the ANTS website.

Choose a suitable self-test

AMA Prévention offers the three-threshold THC test as well as multi-drug urine panels. Check the substance, threshold, expiration date, and instructions before use.
