Securetech Drugwipe 5s test: Illegality of using a threshold of 5 ng/ml for THC

Testing for illegal substances plays a crucial role in law enforcement operations to ensure public safety. These tests, carried out from saliva or urine collections, are governed by minimum detection thresholds established by law. This article explores current legal thresholds and examines why THC saliva tests with a positivity threshold of 5 ng/ml, such as the SecureTech DrugWipe 5S, may raise legal concerns.

Minimum Detection Thresholds for Saliva Tests

Saliva drug tests are frequently used to detect the presence of illegal substances. The minimum detection thresholds for certain substances are set by law:

1. Cannabinics :
- 9-tetrahydrocannabinol (THC): 15 ng/ml of saliva;

2. Amphetamines :
- Amphetamine: 50 ng/ml of saliva;
- Methamphetamine: 50 ng/ml of saliva;
- Methylene dioxymetamphetamine (MDMA): 50 ng/ml of saliva;

3. Cocainics :
- Cocaine or benzoylecgonine: 10 ng/ml of saliva;

4. Opiates :
- Morphine: 10 ng/ml of saliva;
- 6 mono acetylmorphine: 10 ng/ml of saliva.

These thresholds ensure a balance between the need to detect the use of illegal substances and respect for individual rights.

Minimum Detection Thresholds for Urinary Tests

Urine tests are also common, with minimum detection thresholds established by law:

1. Cannabinics :
- Tetrahydrocannabinol carboxylic acid (9 THCCOOH): 50 ng/ml urine;

2. Amphetamines :
- Amphetamine: 1,000 ng/ml urine;
- Methamphetamine: 1,000 ng/ml urine;
- Methylene dioxymetamphetamine (MDMA): 1,000 ng/ml urine;

3. Cocainics :
- Cocaine or benzoylecgonine: 300 ng/ml of urine;

4. Opiates :
- Morphine: 300 ng/ml urine.

Legal Implications of a Threshold of 5 ng/ml

The use of tests with a positivity threshold of 5 ng/ml can raise significant legal issues. Such a low threshold can lead to positive results for minimal traces of substances, compromising the validity of the results and violating individual rights to privacy and the presumption of innocence.

In France, the law provides for tests with a detection threshold of 15 ng/ml, as indicated in the following data:
- For cannabinics, such as 9-tetrahydrocannabinol (THC), the threshold is 15 ng/ml of saliva.
- For amphetamines, such as amphetamine, methamphetamine and methylene dioxymetamphetamine (MDMA), the threshold is 50 ng/ml of saliva.
- For cocainics, such as cocaine or benzoylecgonine, the threshold is 10 ng/ml of saliva.
- For opiates, such as morphine and 6 mono acetylmorphine, the threshold is 10 ng/ml of saliva.

These thresholds, established by law, aim to guarantee more reliable results and to limit the risks of positive results induced by the presence of minute traces of substances. By complying with these standards, saliva testing can better meet legal requirements and protect individuals' fundamental rights, including the right to privacy and the presumption of innocence.

Continued reflection on these thresholds will ensure that testing methods remain up-to-date, accurate and compliant with ethical requirements, while contributing to an essential balance between safety and the protection of individual rights. It is also important to emphasize that people tested with a saliva test who have a threshold lower than that provided by law are entitled to question the procedure and appeal the sanctions incurred. This highlights the importance of rigorous and fair law enforcement in the drug testing process, ensuring that individual rights and freedoms are respected at every stage of the process.
