Choosing the right policy for your company is a strategic decision that supports company values and employee wellbeing while maintaining a safe work environment.
Most employers don't think much about their substance use policy until something goes wrong, and that moment rarely arrives in an obvious way. It's usually a manager who notices a behavioral shift but doesn't know what to say, or an employee who's been struggling for months before anyone finds out. By then, a policy that was never quite right starts to matter in ways you weren’t prepared for.
Choosing a workplace substance use policy is one of the most consequential workforce decisions your company will make, and it deserves the same care you’d give any other major benefits or culture decision. Get it right, and it protects your employees, your managers, and your organization. Get it wrong, and it can quietly undermine all three.
This post walks through the two main policy types, how to think through the right fit for your organization, and what it takes to make any policy work once it’s in place.
The scale of substance use in the workplace is easy to underestimate. A recent survey found that 22.5% of people admit to using drugs or alcohol during work hours.
And the impact isn’t evenly distributed across industries or roles. CuraLinc’s peer-reviewed study of more than 85,000 employees across eight major industries found that among employees who contacted the employee assistance program (EAP), the manufacturing sector had the highest rate of workers at risk of alcohol misuse, followed by the retail and transportation sectors. That kind of industry-level variation matters because a substance use policy that works well for a corporate office may not translate to a facility where employees operate heavy equipment, drive commercial vehicles, or provide direct patient care.
Beyond the workforce safety implications, there are real financial consequences. Untreated substance use disorder is associated with higher rates of absenteeism, increased healthcare claims costs, more workers’ compensation activity, and reduced productivity across teams, not just for the employee who’s struggling, but for the colleagues and managers around them.
A well-designed policy doesn’t eliminate these risks entirely, but it creates a structure that makes early intervention possible and gives everyone, from employees and managers to human resources leaders, a clear path to follow when a concern arises.
A zero-tolerance workplace substance use policy prohibits employees from using drugs or alcohol before, during, or after work hours, with termination as the consequence for a verified violation. Companies using this model typically require drug screenings before employment, at random intervals, or following a workplace accident.
Zero-tolerance policies tend to be most appropriate in environments where employees hold safety-sensitive positions, such as commercial pilots, heavy machinery operators, construction workers, healthcare professionals. In roles where impairment creates immediate risk of harm, there is little room for discretion.
One nuance worth considering is that some employers with zero-tolerance policies also maintain a self-disclosure provision. This allows employees to come forward before a positive test triggers formal action. When combined with a structured support process like a formal management referral through an EAP, this approach can coexist with strict policy standards while still giving employees a pathway to treatment.
A second-chance policy gives employees the opportunity to remain with the company after a verified positive drug test, provided they meet specific conditions, such as completing a treatment program, agreeing to increased testing, or participating in a formal referral process. For employees in safety-sensitive roles, second-chance policies typically include stricter parameters, such as an automatic suspension period before return to work.
The choice between zero-tolerance and second-chance isn’t always obvious, and it doesn’t have to be permanent. Many organizations use elements of both, maintaining zero-tolerance standards for safety-sensitive roles while applying second-chance provisions to employees in lower-risk positions.
The most important thing to know is that no policy is right for every company. There are a few questions worth considering before you decide:
What roles does your workforce hold? If a significant portion of your employees are in safety-sensitive positions, zero-tolerance provisions are likely necessary for those roles, regardless of what the rest of your policy looks like.
What does your legal and compliance environment require? Certain industries, like Department of Transportation-regulated employers, federal contractors, and healthcare organizations, have specific mandated requirements that will impact your choice. Compliance isn’t optional, so the policy you choose must reflect those obligations.
What substances are most relevant to your workforce? This matters more than many employers realize. Alcohol is frequently the primary substance involved in workplace impairment, but cannabis creates a specific testing challenge. THC can remain detectable in urine for up to 30 days after use, meaning a positive test doesn’t necessarily indicate current impairment. As more states continue to expand cannabis legality, employers face real questions about how to handle testing results and what the policy implications are.
What does your company culture support? A second-chance policy without genuine leadership buy-in and proper EAP support will not work as intended. Employees need to believe that coming forward won’t cost them their jobs before they’ll take action.
A policy document is only as effective as the infrastructure around it. The employers who see the best outcomes from their substance use tend to have a few things in common.
An employee assistance program should be embedded in the substance use policy itself. When an employee tests positive or self-discloses, there should be a clear and immediate pathway to the EAP. Employees must be able to access an initial assessment quickly.
For example, CuraLinc members have access to live licensed clinicians 24/7/365. After assessment, members who need structured substance use disorder support have access to treatment starting in 48 hours, with up to 24 months of aftercare support to stabilize real-life factors fueling substance use.
Don’t expect your managers to act as clinicians, but instead, partner with your EAP to offer appropriate training in how to identify signs of substance use. Management consultation services through an EAP provide supervisors with an extra layer of support and a place to turn when they’re concerned about an employee’s behavior.
Formal management referrals (FMRs) take this a step further, providing a structured process to address a policy violation, connect the employee with treatment, and keep HR appropriately informed about progress without violating the employee’s privacy.
We’ve found that 21% of formal management referrals are initiated because of substance use concerns related to alcohol, and after completing the counseling required as part of an FMR, 83% of employees identified as being at risk of alcohol use disorder were no longer at risk. That is the difference between losing a trained employee and helping them return to full productivity.
The most common reasons employees don’t seek help for substance use are fear of judgment, fear of job loss, and not knowing where to turn. A policy can outline all the right things and still fail if employees don’t trust it. Building a recovery-supportive workplace means communicating consistently about available resources, ensuring that managers model a non-stigmatizing response to behavioral health concerns, and creating pathways to support that feel safe and confidential.
The right substance use policy for your organization is one that aligns with your workforce’s risk profile, meets any legal and compliance obligations, and is genuinely supported by the mental health and EAP infrastructure around it. Zero-tolerance and second-chance are both tools, and the right combination depends on your organization’s needs.
Across policy types, employees facing substance use challenges have better outcomes when they have a clear, trusted, low-barrier path to care. Building that path through a strong EAP partnership, trained managers, and a culture that treats recovery as a real possibility is what separates a policy that’s printed in your employee handbook from one that makes a meaningful difference.
