Médisur: France's specialist in health, safety & QWL (Quality of Work Life) prevention in companies
Who is Médisur?
Medisur is the expert in health prevention and QWL (Quality of Working Life)
Medisur offers a wide selection of training health, well-being and safety adapted to individual needs to make your CSR policy a real lever for performance for the company.
A great, unique experience both on-site and remotely
Medisur offers its exclusive method which combines awareness-raising and active employee participation through Health kit by Medisur and animation by health professionals.
Medisur's activity is based on three complementary pillars:
- certified training courses, led by expert speakers on each topic, to impart the right reflexes.
- screening devices (self-tests) conforming to current standards, in order to objectify a situation rather than assume it.
- health kits, designed so that each employee leaves with a tool that they can actually use, long after the intervention.
What certifications does Medisur have?
Two certifications underpin the company's credibility. ISO 13485:2016 certification covers the import and distribution of medical devices and in vitro diagnostic medical devices. Qualiopi certification, This aspect focuses on training activities. This dual foundation reassures both HSE (Health, Safety, and Environment) departments and purchasing managers, who are accustomed to demanding documented guarantees before engaging a health partner.
Medisur is not just a distributor. Lab' Medisur, [Company Name], a French integrated laboratory, develops several ranges of rapid diagnostic tests distributed to pharmacies, laboratories, and hospitals. This industrial expertise, from design to distribution, explains why the saliva self-tests mentioned below meet validated thresholds and protocols, and not just marketing claims.
This expertise is also recognized beyond its own sector: Medisur has been supported by the Bpifrance accelerator, benefits from the backing of the South Region, and holds the French Care label, which distinguishes French players in healthcare innovation. These external accolades reinforce what client companies observe on the ground: a serious, well-documented organization that provides ongoing support, rather than a one-off service provider.
Medisur offers a comprehensive guide to health and safety prevention
Cannabis remains, after alcohol, the leading cause of positive roadside drug tests in France. It also silently impacts workplace safety. Faced with this reality, THC saliva self-test It has established itself as a simple tool to open up dialogue, before an accident does so instead of prevention.
This guide brings together everything that an HR manager, an HSE prevention officer, a pharmacist or an individual needs to know on the subject: how a saliva self-test works, what the law says, how to structure a prevention policy in a company, and how Medisur has been concretely supporting these approaches for more than ten years.
Cannabis and THC: an underestimated risk to health and safety
Δ9-tetrahydrocannabinol, or THC, is the main psychoactive component of cannabis. Once consumed, it acts on the central nervous system, altering sensory perceptions, causing loss of coordination, and memory problems. Some users also report anxiety, paranoia, confusion, or an increased heart rate. Each of these effects directly impairs the ability to drive a vehicle or perform a safety-sensitive job.
The scale of the phenomenon is not insignificant. In France, approximately 17 million people report having used cannabis at least once in their lives, 4.6 million in the past year, and 700,000 use it daily. These figures inevitably include a portion of employees, professional drivers, and road users encountered every day.
For a company, the challenge isn't to moralize its employees' personal practices. It's to ensure the safety of high-risk positions, business trips, and driving, based on facts rather than suspicions. This is precisely the role of an objective screening tool like a saliva self-test.
Understanding the THC saliva self-test: principle and operation
The biological principle is the same for all cannabis saliva tests The market's reliability: antibodies directed against Δ9-THC react to its presence in a saliva sample. If the measured concentration reaches or exceeds the established threshold, the test displays a positive result.
In practice, the user collects a sample using a collector equipped with a saturation indicator. This indicator changes color—usually to pink or red—when the volume of saliva collected is sufficient to guarantee a reliable result. The device is then closed, and the result is displayed within two minutes as control and test lines, which must be read within a window of ten to twenty minutes after the procedure. Beyond this timeframe, the reading is no longer considered reliable.
One point deserves to be reiterated to users, as it generates recurring questions: the intensity of the lines is irrelevant. Only their consistent and continuous presence matters for interpretation. An absent control line means the test failed and must be run again.
Detection thresholds, reliability and detection window: what you need to know
The cannabis saliva self-tests The tests distributed by Medisur have a detection threshold of 15 ng/mL, identical to that used by the saliva tests employed by the National Gendarmerie and the National Police under Articles R. 235-3 and R. 235-4 of the French Highway Code. This is no coincidence: it is what allows the self-test to serve as a realistic benchmark before driving.
The detection window varies depending on the frequency of use, the dose, and each individual's metabolism. For an occasional user, meaning less than twice a week, the test generally remains positive for up to about twelve hours after the last use. The logical recommendation that follows is to wait at least twelve hours before driving after using drugs, and to consider that a negative test at this stage corresponds, in most cases, to what a police check would detect.
Regarding reliability, the available clinical data on the Medisur cannabis range, Compared to a reference laboratory method (liquid chromatography coupled with mass spectrometry), the results show an overall concordance rate close to 98% (%) on a panel of 90 samples. This level of performance justifies the use of the self-test as a reliable self-assessment tool, provided the instructions are strictly followed: insufficient saliva or a test handled prematurely can skew the result, generally leading to a false negative.
Legal framework: what does the law say about cannabis testing in France?
Unlike alcohol, for which the law allows a residual level, cannabis use remains prohibited in France with no legal blood alcohol limit for driving. The saliva-based devices used by law enforcement comply with a decision of the Council of State (CE No. 394178 of December 5, 2016), which regulates their use during roadside checks.
This difference in treatment has a direct consequence for businesses and individuals: a cannabis saliva self-test is in no way a tool for anticipating or circumventing a test. Its purpose is the opposite: to give the user reliable information about their own status, so that they can adjust their behavior—postpone a trip, inform their employer, avoid taking a high-risk position—before someone else does it for them, in a much less favorable context.
In business, the employee screening It operates under an even stricter framework. It can only apply to positions identified as sensitive for security, must be stipulated in the company's internal regulations, and is accompanied by safeguards for the employee: consent, presence of a authorized person, and the right to a second medical opinion in the event of a disputed positive result. A credible prevention policy systematically relies on this three-pronged legal framework—training, information, and documented procedure—rather than on an isolated test decided in haste.
Workplace road safety: road risk, the leading cause of death at work
Occupational road risk remains, even today, the leading cause of fatal accidents in the workplace, across all sectors. Commuting, client visits, driving commercial vehicles or machinery: the exposure affects a much larger proportion of the workforce than just those in road-related professions.
An effective prevention policy combines several levers. Professional Road Risk Training The training offered by Medisur, for example, includes a review of legal obligations regarding work-related travel, an analysis of controllable and uncontrollable risk factors, a focus on eco-driving, and practical exercises tailored to the company's core business. The format, available in person or remotely, is designed for groups of fifteen to twenty people and concludes with an assessment of learning outcomes.
In addition, the Road safety kit It includes a multi-drug self-test, two breathalyzers, and a guide to life-saving first aid, so that each employee has a means of independent self-checking before driving. This is one of the core principles of the Medisur method: collective awareness is not enough if it is not accompanied by an individual tool that is immediately available.
Workplace screening: a structured procedure that respects employees
Set up a psychotropic drug screening In a company, this kind of testing cannot be improvised. The process always begins with a clear explanation of the procedure to the employees and managers involved, before any implementation. The test is then only offered to positions identified as sensitive, and its execution requires the employee's agreement as well as the presence of an authorized person who has previously verified the proper functioning of the equipment.
Two outcomes are possible. If the result is negative, the employee returns to work, unless their observed behavior warrants further treatment. If the result is positive, treatment is arranged without delay, and the employee retains the right to request a second medical opinion to contest the result.
This procedural rigor is not an administrative obstacle; it is what legitimizes the approach in the eyes of the teams. Screening perceived as arbitrary or punitive undermines the social climate. Conversely, screening that is documented, explained, and accompanied by safeguards becomes a collectively accepted safety tool.
The Medisur method: raising awareness, equipping, supporting
The effectiveness of a prevention policy rarely hinges on a single isolated action. Medisur structures its support around a method which combines three complementary steps: raising awareness among teams by healthcare professionals, providing health kits for independent actions, and access to interactive dialogue sessions with experts.
This approach addresses a finding shared by most HR departments: a one-off conference without concrete follow-up is quickly forgotten. Conversely, an employee who leaves with a self-test or breathalyzer in their health kit retains a readily available self-checking tool, months after the initial presentation.
The prevention themes are intentionally interconnected: road safety, work addiction, Mental Health, lifestyle Or intimate health are structured within the same annual calendar, so that health prevention becomes a continuous policy rather than a succession of isolated operations.
Two key moments for intimate health: Pink October and Movember
Every year in October, Medisur supports companies in their participation in Pink October, This is National Breast Cancer Awareness Month. This cancer affects one in eight women in France and remains the most common cancer among women, with more than 58,000 new cases diagnosed each year; however, when detected early, it is curable in 90% of cases. To spread this message, Medisur offers several combinable formats: conferences and webinars led by a healthcare professional, interactive displays at booths, practical self-examination workshops, and a dedicated health box combining a self-examination pad and an interactive e-guide. The workshop, in particular, allows employees to learn this screening technique in a supportive and confidential environment, with a healthcare professional available to answer their questions.
Medisur carries the same commitment to men's health through Movember, an international movement that began in Australia in 2003 and is celebrated every November. It highlights three key issues: prostate cancer, the second most common cancer among men worldwide; testicular cancer, particularly prevalent in men aged 15 to 35; and men's mental health. In the corporate world, Medisur promotes this awareness through conferences and participatory workshops, complemented by a Movember health box including a self-test that measures PSA (prostate-specific antigen) levels, an indicator used for the early detection of prostate cancer. As with Breast Cancer Awareness Month (October), the Movember workshop primarily aims to encourage open discussion on topics that are still too often taboo, by providing employees with concrete information on male anatomy and self-examination techniques.
Our prevention program focuses on road safety and addictions.
Medisur's offering, centered around the THC saliva self-test, covers the entire prevention process, from awareness campaigns to on-the-ground tools: certified training courses, participatory workshops, supervised screening, health kits, and a range of self-tests. Details of each training course are presented below, allowing HR or HSE departments to choose the format best suited to their needs.
Professional Road Risk Training
This is the benchmark module on road safety in the workplace. Delivered in a half-day session (3.5 hours) on-site at your company, or in a two-hour online format, for groups of 15 to 20 people, it reviews legal obligations regarding work-related travel, analyzes controllable and uncontrollable risk factors, addresses eco-driving, and concludes with practical exercises tailored to the company's core business. No prior knowledge is required, and an assessment of learning outcomes concludes the session.Training in the protocol for managing highly sensitive positions involving drugs and alcohol
Designed for managers and anyone required to conduct tests in the workplace, this Qualiopi-certified training course is delivered in-person, over half a day, for small groups of 10 to 15 people. The content covers the legal framework (Labor Code, internal regulations, Single Risk Assessment Document - DUERP), the correct reading and interpretation of screening tests, a practical workshop on conducting a saliva test in compliance with regulations, and the procedures to follow in the event of a positive result. Each participant receives a certificate of completion and competence.Drug and alcohol awareness for employees
This shorter module is designed for all teams. Delivered in person, either in-house or at other companies, it lasts approximately 1 hour and 15 minutes, adaptable to specific needs, for groups of around twenty people. It explains psychoactive substances and their effects on the brain and behavior, then the mechanisms of addiction. The session can conclude with an anonymous and voluntary mapping of alcohol and drug use within the group: a concrete starting point for developing a prevention action plan, rather than simply raising individual awareness.
Psychotropic drug screening workshop
This module implements the screening procedure itself, within the company and on demand, for groups of up to 40 people. It relies on saliva tests, a sign-in sheet and a results mapping system, and follows a strict procedure: prior explanation to employees and managers, offer of the test, employee consent, administration by an authorized person, then appropriate follow-up based on the result obtained.
Auditing and consulting in workplace addiction
This module is designed for companies that want to build a structured addiction prevention policy, rather than simply implementing isolated initiatives. An expert assesses existing practices related to alcohol, tobacco, psychotropic medications, and illicit drugs, and then formulates tailored recommendations. This approach is fully aligned with a CSR (Corporate Social Responsibility) framework, encompassing the social, societal, and economic aspects of the company's prevention policy.
Soft mobility
In addition to addressing traditional road safety risks, this module supports the evolving use of work-related travel: cycling, two-wheeled vehicles, and other forms of active transportation. It raises awareness among teams regarding mandatory equipment and best practices specific to these modes of transport, which are increasingly common for commuting and business trips.
Beyond their specific content, these training courses share a common pedagogical approach. Each session begins with a round-table discussion and an interactive quiz to assess participants' prior knowledge without judging them. It then relies on concrete materials: case studies, role-playing exercises, video analysis, and simulations directly inspired by the client company's business. This deliberately participatory approach explains why feedback from the field regularly describes the training as useful and practical, rather than simply a regulatory requirement.
Each training course can be deployed individually or combined as part of an annual prevention plan, aligned with key periods of the HR calendar Road safety week in May, quality of life at work week in June, mobility week in September. These training sessions naturally complement the Road safety kit (multi-drug self-tests, breathalyzers and first aid guides) and the range of saliva and urine self-tests — cannabis, multidrugs six classes, alcohol, nicotine — available individually for businesses, pharmacies and individuals.
Who is this prevention approach aimed at?
The issue of THC saliva testing concerns populations with very different needs, which Medisur addresses separately:
For the companies, HR and officials HSE/QSE, The challenge is to integrate addiction and road safety prevention into a coherent, documented, and compliant occupational health policy. For the security officials, Self-testing becomes an operational tool to be integrated into the procedures of sensitive positions. For the pharmacists And wholesalers, Certified self-tests represent a highly useful public health product, with ready-to-use displays and sales materials. For the insurers, These measures are part of a risk prevention strategy, likely to reduce accidents related to work-related travel. Finally, for the individuals, The self-test remains primarily a self-assessment tool, useful after a night out or before driving again, and directly accessible on the Medisur e-shop.
How to use a cannabis saliva self-test correctly: instructions and precautions
A few simple rules ensure the reliability of the result. Do not eat, drink, or smoke for ten minutes before the test. The sample collector must remain in your mouth until the saturation indicator changes color: collecting the sample too quickly is the primary cause of inaccurate results. The test is for single use only, should be stored between 2°C and 30°C, must never be frozen, and must be used before its expiration date, with the sachet intact.
The result must be read within the window indicated in the instructions, generally within ten to twenty minutes of the procedure. After this time, the interpretation is no longer guaranteed. If you have any doubts about the procedure or a result, consult the complete instructions and a... Detailed FAQ accompany each box, and a new test must be carried out if the control line does not appear.
Why self-testing is a tool for dialogue, not a tool for police control
It is important to put the saliva self-test into its proper context. It is not a way to evade a police check: French law does not set any tolerance threshold for cannabis use while driving, and misusing the test for this purpose would expose the driver to the same criminal penalties anyway.
Its true value lies elsewhere. It's a self-assessment tool, intended for both the user and those around them, to objectively assess a situation and open a conversation that would otherwise remain unspoken. In business, this same principle applies on a larger scale: giving teams a concrete way to check their readiness before a trip or a shift is better than a preventative message without practical application.
