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. Limiting your panel to cannabis, cocaine, amphetamines, opioids, and PCP leaves serious gaps. Substances like fentanyl, benzodiazepines (think Valium™), and many over-the-counter drugs (such as Wake-Ups™) are widely used … Read more
Substance use in the workplace is a complex issue, one that goes far beyond testing or identifying who used what and when. At its core, it is about safety and accountability, and a workplace culture that supports both. Whether we like it or not, substance use will always exist in some form. The real question … 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. Some of you may know this as a … Read more
As workplaces continue to evolve their substance use policies, one recurring question is this: Can safety risk really be measured objectively?

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

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

It’s a time for connection and relaxation and also an important moment to consider best practices around social hosting and workplace safety when alcohol or other substances are often a part of the festivities.
