Cannabis urine test

Drugdiag® THC: cannabis THC-COOH urine test at 50 ng/mL

The Drugdiag® THC urine test is a professional screening device designed to detect THC-COOH, the main urinary metabolite of cannabis. Unlike saliva tests, which detect active THC over a short period, the urine test can identify older consumption.

Developed by Toda Pharma, France’s leading rapid diagnostic test laboratory, this cannabis urine test offers a detection threshold calibrated at 50 ng/mL. It is suitable for self-testing, license recovery, medical monitoring, and workplace prevention procedures.

Certified CE, compliant with ISO 13485 standard and designed for professional use, it offers a fast, simple, and reliable reading, with over 99% correlation with the reference GC/MS method.

Detection of urinary THC-COOH
Standard threshold: 50 ng/mL
Ideal for license recovery, workplace, and monitoring

Detected substance

The Drugdiag® THC urine test detects THC-COOH, the main cannabis metabolite eliminated in urine. It is suitable for situations where the goal is to verify past use or abstinence over a longer period than saliva.

THC-COOH
Urinary cannabis metabolite, resulting from the breakdown of THC by the body.
50 ng/mL
Flowers
Classic cannabis, weed, marijuana, pot.
THC-COOH
Resin
Hashish, pollen, cannabis resin.
THC-COOH
Concentrates
Oils, wax, rosin, e-liquids, or concentrated products containing cannabis.
THC-COOH
Edibles
Infused food products, cakes, candies, or preparations containing cannabis.
THC-COOH
CBD
Full-spectrum CBD products: a positive result is possible in case of residual THC accumulation.
Positive risk

This urine test does not directly detect active Δ9-THC in saliva. It detects THC-COOH, the urinary metabolite of cannabis, allowing for a longer detection window.

Warning: CBD and positive result

Pure CBD is not targeted by the test. However, some full-spectrum CBD products may contain residual traces of THC.

In case of regular consumption of flowers, resins, or CBD oils containing residual THC, THC can accumulate and then be eliminated in urine as THC-COOH, with a risk of a positive result.

Recommended uses

License recovery

The Drugdiag® THC urine test is particularly suitable for self-testing before a medical visit, medical commission, or official analysis. It helps verify if urinary traces of cannabis remain detectable.

Workplace safety

In the workplace, it can be part of a risk prevention approach for sensitive or security positions, respecting internal regulations, confidentiality, and the applicable framework, notably article L.4121-1 of the Labor Code.

Medical monitoring and prevention

This test can be used for medical monitoring, support for cannabis cessation, or individual prevention, with a quick and easy-to-interpret result.

Urine detection windows

Unlike the saliva test, which provides information on recent use, the urine test allows identification of past use through detection of THC-COOH.

Occasional
Single or very occasional use: indicative detection duration generally between 1 and 3 days.
Indicative
Regular
Several consumptions per week: indicative detection possible between 5 and 12 days depending on profiles.
Variable
Chronic
Daily or heavy use: detection possible up to 30 days, sometimes longer in some individuals.
Variable

Detection times are given as an indication. They vary depending on metabolism, consumption frequency, product concentration, BMI, hydration, and other individual factors.

Negative result

A negative result indicates that THC-COOH was not detected above the 50 ng/mL threshold. This does not guarantee the absolute absence of any trace but indicates the test threshold was not reached.

Positive result

A positive result indicates a reaction compatible with the presence of THC-COOH in urine. For any official or disputed procedure, confirmation by a laboratory analytical method is recommended.

Invalid result

An invalid result may be due to improper handling, insufficient sample volume, or failure to respect the reading time. In such cases, the test should be redone with a new device.

Technical expertise

Colloidal gold technology

The device uses competitive immunochromatography with colloidal gold-labeled antibodies. This technology allows for a clear, rapid visual reading suitable for professional use.

GC/MS reliability

The test accuracy was compared to the laboratory reference method, gas chromatography coupled with mass spectrometry (GC/MS), with an accuracy correlation above 99%.

Quality compliance

Designed by the French laboratory Toda Pharma, this in vitro diagnostic medical device is CE marked and meets quality standards compliant with ISO 13485.

Frequently asked questions

What exactly does the Drugdiag® THC urine test detect?

It detects THC-COOH, the main urinary metabolite of cannabis. This metabolite can remain detectable longer than the active THC sought in saliva.

What is the difference with a THC saliva test?

The saliva test mainly detects active THC over a short window, often related to recent use. The urine test detects THC-COOH, which can remain present longer in the body.

Is this test suitable for license recovery?

Yes. It is particularly useful for self-monitoring before a medical visit or official analysis, as it allows checking if THC-COOH remains detectable in urine.

Can CBD cause this test to be positive?

Yes, in some cases. Pure CBD is not the target of the test, but CBD products containing residual traces of THC can cause a positive result, especially with regular use.

How long does cannabis remain detectable in urine?

The duration depends on the consumption profile. It can be about 1 to 3 days for occasional use, 5 to 12 days for regular use, and up to 30 days or more for some chronic users.

Does a positive result have definitive legal value?

No. A positive result on a rapid test is a preliminary result. For any official procedure, confirmation by laboratory analytical method is recommended.

Need advice or a quote for a professional order?

Expert FAQ: Prevention & Risks

How long do drugs remain detectable with this urine test?

Unlike saliva testing, urine analysis retains traces of drugs and medications for a much longer period. Each substance has its own detection window, which can range from a few days to several weeks depending on your metabolism and frequency of use. Knowing how long your body takes to completely eliminate these molecules is essential. Buying a urine test allows you to accurately assess this detection window and clear up any doubts safely.

Does this device detect the same substances as the police and gendarmerie?

Absolutely. The Drugdiag T is calibrated to the official European cut-offs. It simultaneously targets the narcotics sought by the police and the gendarmerie (THC, cocaine, opiates, amphetamines), offering you professional-level reliability before getting behind the wheel.

How to avoid a false positive urine test?

The reliability of our diagnostic devices exceeds 99%. To eliminate any risk of false positives, carefully follow the instructions: dip the device in urine, wait 3 minutes, and read the result. The appearance of a single control line (C) without a test line (T) confirms a positive urine test.

Can CBD trigger a THC detection?

Yes, it is a well-known risk. Legal CBD contains tiny traces of THC which, when accumulated, can result in a positive test. Self-testing is essential to verify your fitness to drive or to anticipate a medical review for license reinstatement after a suspension.

Is it suitable for workplace screening?

Exactly. This multi-parameter kit is ideal for occupational physicians and employers looking to prevent risks. The rapid detection of benzodiazepines and synthetic drugs helps secure critical positions, in full compliance with the recommendations of the Labor Code.

French manufacturing and medical quality

Toda Pharma, a French manufacturer of drug screening tests, was one of the first European laboratories to develop a rapid serological test for coronavirus detection as early as February 2020 and was validated by the National Reference Center (CNR), the Pasteur Institute, and the French Ministry of Solidarity and Health.
