Avoiding Common Employer Pitfalls: Drug Testing in the Hiring Process

Pre-employment drug testing remains a common practice—especially in industries where safety is a top priority. But as legal standards evolve, employers face growing risks if their testing policies are not carefully tailored to comply with federal, state, and local requirements. Key legal developments in disability law, medical and recreational marijuana protections, and privacy rights mean employers must proceed with caution when using drug testing as part of hiring decisions.

This alert highlights common legal missteps and some recent developments to help employers adopt compliant and defensible hiring practices.

1. Disregarding State and Local Protections for Marijuana Users

With more states legalizing medical and recreational marijuana, employers are increasingly expected to take lawful marijuana use into account—particularly when used to treat a disability. Although marijuana remains illegal under federal law, many state laws restrict employers from making employment decisions based solely on a positive test for marijuana. Some jurisdictions, like Philadelphia and New York City, even prohibit pre-employment testing for marijuana altogether.

In several cases, courts have recognized potential claims where employers failed to consider accommodation obligations under state disability statutes. These decisions reflect a trend toward requiring employers to assess whether a positive drug test may be linked to legally protected medical treatment.

2. Applying Rigid Drug Policies Without Case-by-Case Review

Employers who automatically reject applicants based solely on a failed drug test may be vulnerable to claims under the Americans with Disabilities Act (ADA). When prescription medications are involved, employers must assess whether the applicant’s condition qualifies as a disability and whether accommodation is required.

Courts have allowed claims to continue and the EEOC has pursued claims where employers made hiring decisions without conducting an individualized assessment before making a final decision.

3. Testing at the Wrong Time or Without Adequate Disclosure

Conducting drug tests before a conditional job offer is extended—or failing to provide proper notice—may run afoul of laws in jurisdictions with fair hiring rules. These laws are intended to ensure candidates are not unfairly screened out before their qualifications are evaluated.

4. Not Providing an Opportunity to Explain Positive Results

When applicants are not given the chance to explain positive results—particularly where lawful drug use or medical issues may be a factor—employers face heightened legal risk. This is especially true where hiring decisions are made without engaging in dialogue about potential accommodations.

Best Practices for Employers

To minimize legal risk, employers should:

• Conduct drug testing only after a conditional job offer is made and ensure applicants are clearly informed in writing and consent to same.
• Monitor legal developments related to marijuana laws (both medical and recreational), disability rights, and workplace privacy in the jurisdictions in which you operate and/or have employees.
• Utilize trained Medical Review Officers (MROs) to evaluate test results and determine whether they are tied to lawful prescriptions.
• Avoid rigid policies that disqualify applicants solely on the basis of a failed test without further analysis.
• Train hiring managers and HR staff to recognize when legal issues may be implicated and to escalate sensitive matters appropriately.

Conclusion

While drug testing can be a useful tool to promote workplace safety and integrity, legal missteps in the process can expose employers to liability. By aligning testing policies with current legal standards, ensuring transparency, and considering individual circumstances, employers can reduce risk and protect both their workforce and reputation.
