Frequently Asked Questions about Saliva, Urine Screening Tests, and Breathalyzers

To comply with police and gendarmerie controls, our tests detect molecules according to legal thresholds:

• Cannabis (THC): 15 ng/ml
• Cocaine: 10 ng/ml
• Opiates: 10 ng/ml
• Amphetamines: 50 ng/ml
• Methamphetamines (MDMA): 50 ng/ml

Our tests OkTest® THC and Drugdiag® Saliva 5 strictly comply with these sensitivity levels.

This is a common concern. However, the thresholds at 15 ng/ml are calculated to avoid "false positives" related to simple passive exposure. To test positive, direct inhalation or ingestion of the substance is required.

In case of a fatal accident with the presence of narcotics, the penalty is now harsher under the qualification "Road Homicide," with automatic license cancellation. Preventive self-testing is more than ever a safety reflex.

The employer risks a conviction for Inexcusable Fault if prevention measures are not implemented. The employee risks dismissal for gross misconduct. The DUERP must imperatively include these risks.

Time is crucial because substances disappear quickly (a few hours for blood, 8 to 12h for urine). Do not urinate before arriving at the emergency room. Call immediately 15 (SAMU) or 17 (Police). If you cannot speak, use 114 (SMS).

There are specialized organizations to help you through this ordeal:

• The CRAFS: For expert medical and toxicological follow-up, visit the CRAFS (Reference Center for Addictovigilance) website.
• M'endors pas: For victim support and awareness, contact the association M'endors pas.
• Women Rape Information: Call 0 800 05 95 95 for anonymous and free support.

No. The CRAFS network indicates that many molecules are used: benzodiazepines, antihistamines, or neuroleptics. Demand a rapid biological sample for broad toxicological analysis, not just a GHB test.

Hair analysis remains the solution. A strand taken 4 to 6 weeks after the event can reveal the presence of drugs administered occasionally, where blood and urine no longer show traces.

Legal CBD often contains traces of THC (up to 0.3%). These traces can accumulate and trigger a positive test at the 15 ng/ml threshold. For a driver, this is a major administrative risk.

Standard tests do not detect them. Specific tests like our urinary formats Drugdiag® 4T to 12T must be used to detect these NDS (New Synthetic Drugs).
