Workplace drug testing isn’t nearly as common a problem for workers as one might believe, but there is growing evidence for a need for greater employer caution regarding employee drug use. Findings from The Drug Detection Agency’s Q1 2026 report showed that cocaine detections in Australian workplaces rose 45.4% YoY, with the detection of amphetamine-type substances also climbing.
In a similar vein, the 2026 Quest Diagnostics Drug Testing Index found that nearly one in five workers, or 19.1% of them in the general U.S. workforce, tested positive for drug use. This was based on the analysis of hair specimens that were collected in 2025, and marked a 46% increase in numbers when compared to data from 2021. While marijuana accounted for 52.5% of hair drug positives in 2025, cocaine positivity also went up to 4.0%, while amphetamine detections also rose to 2.3% in 2025. The data doesn’t signal a need to sound the alarm, but instead suggests the need for caution.
None of the data indicates that the rise in substance use or detection of use directly implies the consumption of drugs within the workplace or on the job. Many of these increments could be tied to the increasing legalization of marijuana or reliance on such substances for factors like pain management or treatment, which are often prescription-based. What falls within the employer’s purview includes public service announcements, internal training on the safe use of substances, and alerts to prevent drug use during working hours, ensuring that safety standards are upheld in the workplace.

Is Workplace Substance Abuse on the Rise? Data Gathered from Workplace Drug Testing
A 46% increase in evidence of substance use from workplace drug testing is certainly an interesting statistic, with one in 5 workers found to engage in chronic drug use. The Quest report also revealed the industry where employee drug use was most apparent, with retail trade showing the highest marijuana positivity among worker categories, and healthcare workers scoring the highest for overall drug positivity. There are likely many factors that account for the shift in evidence of workplace substance abuse, ranging from increased accessibility to stress factors that promote use.
Does this indicate a need to make workplace drug testing mandatory for all institutions? Not necessarily. The rise in quality and capabilities of workplace drug testing could account for some of the changes in numbers. With most workplace drug testing, the data can vary based on the method of collection. Oral fluid testing allows for a shorter detection window, capturing recent or immediate use, whereas hair testing can reflect patterns of drug use within a 90-day period. Unless incidents result in immediate testing that captures recent use within the last few hours, penalizing employees for their personal habits outside of work can come with repercussions.
The Legal Landscape Regarding Workplace Substance Abuse Can Be Complex
Not all substances are made equally, as some are significantly more detrimental to the employee and the workplace than others. Employees may have many personal reasons to justify their drug use that fall outside of the employer’s right to question. Last year, the U.S. Equal Employment Opportunity Commission (EEOC) filed a lawsuit against an employer that refused to hire a methadone user. Methadone is often recommended as a medication that former substance users can rely on during their recovery from their addiction, and refusing to hire them can be interpreted as a violation of their rights under the ADA, leading to more trouble for the employer.
Not all substance use at work is likely to come with such justifiable cause, however, employers must exert caution when attempting to monitor and police employee drug use. The moment an employer decides to begin cracking down on workplace substance abuse through drug testing, they take responsibility for the data collected and the consequences of the information that is found. Choosing to ignore a worker who is evidently impaired on the job can have just as dire consequences as rushing too fast to penalize employees with faint traces of substances detected in their systems.
With every bit of data that is ultimately detected, employers will have to tread with caution to explore the situation further with the employees and understand the circumstances that led to the results of the testing. Having an HR and legal team on hand to consult with is paramount.
Navigating the Uncomfortable Conversation of Drugs in the Workplace
Discussing substance use at work is never easy, more so when it comes with the adages of safety and warnings of consequences. Still, having a workplace drug policy can be a smart move for employers who want to ensure that employees arrive at work with all their faculties intact. This is particularly important in certain industries, such as in healthcare, where doctors, nurses, and surgeons may be called to perform extremely sensitive tasks, or within factory floors and construction sites, where employees operate heavy equipment.
Active evidence of drug usage within the workplace premises is certainly a concern for employers that demands immediate attention, but it is also critical to explore how the organization will approach this. Employers who intend to conduct workplace drug testing to regularly review the workforce on their adherence to safety standards are best off being transparent about the process to ensure that employees are on the same page and know what they are getting into when they sign up to work for the organization.
Having the details of the testing and the employer’s stance on drugs in the workplace can eliminate some of the future hiccups that come as a result of such testing. Additionally, it is important for employers to solidify their own reasoning for the testing and what the data will be used for. Rather than focus on the drug use itself, as HR Dive suggests, it may be best to focus on impairment tests to ensure that workers can perform their duties unhindered. The employer’s involvement in the matter doesn’t have to stop there. Creating a culture around honest, frank conversations about substance use can open the door to a number of other measures to regulate usage.
How Can Employers Address Employee Drug Use?
Evidence of substance use at work does not have to mean that employers rush to test and fire anyone with even the most remote traces of drugs in their system. This would be a shortsighted strategy of the highest order. Employers and HR teams concerned about workplace substance use can approach the matter in many different ways:
- Address the employees’ working conditions to reduce their reliance on substances. Many workers turn to drugs due to excessive workloads they are stressed over, or stimulants to help them stay awake through successive shifts
- Remind workers of the workplace drug policy and ensure that the details are easily accessible for those who might require a second look
- Train managers and supervisors on how to navigate conversations on employee drug use and what to do if they detect evidence of workplace substance abuse
- Organize regular conversations around the safety standards that are to be maintained at work, with a section on drug use
- Ensure the organization has intervention strategies in place to help employees with substance-related problems seek the help they need
- Have a medical professional on hand or immediate access to first-aid in case of serious issues such as overdose or incapacitation at work. First-aid training for employees can also be a great way to ensure your workforce is prepared for anything. Safety first always
- Create clear strategies on how to deal with workplace substance abuse, which could include time off for those who want to seek treatment, a return-to-work agreement, guidelines on attending meetings, or short-term treatments before reinstatement.
- Explore trainings on how to create a good second-chance hiring program and create support systems that benefit employees
- Revisit local, state, and federal regulations on how to approach employees with a history of substance abuse
When employee drug use turns into abuse, most find themselves in a vulnerable situation that feels out of their control. Serious violations of policy and incidents where there was an active threat to safety must come with consequences that reflect the severity of the violations. But if such tendencies are caught early on, there is still room for employers to extend their support and help the employee work through the problem and emerge stronger. Ultimately, employers are free to determine how to address the situation, but a little empathy can go a long way in ensuring that everyone emerges from the situation better off than ever before.
