Over the past several months, we’ve unpacked one of the most misunderstood concepts in workplace safety: impairment. While the term is used often in policies, legal language, and HR conversations, it’s rarely defined clearly. That lack of clarity creates confusion, inconsistency, and risk. Through a five-part blog series, we’ve looked at impairment from multiple angles: … Read more

Why the “Standard” Drug Testing Panel Isn’t Enough

Many organizations still use the US DOT (Department of Transportation) 5-panel drug test. It’s familiar and referenced in many policies, but is it enough? Not anymore.

Substances like fentanyl, benzodiazepines (think Valium™), and many over-the-counter drugs (such as Wake-Ups™) are widely used … Read more

In my work with safety-sensitive industries, I often hear the same questions when substance use becomes a workplace concern: “What happens next?” “How do we ensure fairness?” “Is this a safety risk or something deeper?” That’s where the role of a Substance Use Expert (SUE) comes in.

Can We Objectively Measure Safety Risk? Why Testing Alone Isn’t Enough

As workplaces continue to evolve their substance use policies, one recurring question is this: Can safety risk really be measured objectively? It’s a fair question and one that doesn’t have a simple answer.

When we talk about fostering safe workplaces and healthy people, it’s easy to focus on policies, training, and testing. But behind the scenes, there’s a critical player ensuring those drug and alcohol testing programs are not only effective, but fair, accurate, and legally defensible. That player? The Medical Review Officer (MRO). As a workplace substance … Read more

As cannabis use becomes more normalized and socially accepted, employers face a growing challenge: how to balance shifting cultural attitudes with the ongoing need to maintain a safe work environment. Let’s continue the conversation about moving away from the vague and often unhelpful concept of “impairment” and focusing instead on safety risk. But even that … Read more

Workplace safety is a top priority, yet many employers still struggle with how to address substance use in a way that is practical, fair, and legally sound. The issue is often framed around impairment, but as I’ve discussed before, impairment is a subjective and emotionally charged term that does little to help workplaces make informed … Read more

Close-up of a person holding a joint, with smoke rising from the end, indicating cannabis use.

As a workplace substance use consultant, I’ve seen firsthand how society often oversimplifies “impairment” as a clear state of incapacity. But the reality is far more complex. Every one of us has experienced some form of impairment—whether from alcohol, fatigue, stress, or other factors—which makes the word profoundly emotional and often misunderstood. In workplace contexts, … Read more
