Employee drug testing programs generate some of the most sensitive records that any employer maintains—records that must be handled, stored, and disposed of with the utmost care and confidentiality. For NYC employers operating drug-free workplace programs, the obligations surrounding drug testing records shredding are both legally significant and ethically important. These records directly implicate an employee’s privacy interests, can affect their livelihood, and are subject to multiple layers of state and federal confidentiality requirements. Getting the disposal of drug testing records wrong can expose employers to privacy claims, discrimination lawsuits, and regulatory scrutiny that no business wants to face.
New York City is home to one of the most complex employment law environments in the country. In addition to federal requirements under the Drug-Free Workplace Act, Department of Transportation (DOT) regulations, and Americans with Disabilities Act guidance, NYC employers must also comply with New York City’s own employee privacy protections and cannabis-related employment rules enacted under the Marijuana Regulation and Taxation Act (MRTA). Understanding how these overlapping frameworks affect your drug testing record disposal obligations is essential for any NYC employer operating a compliant workplace safety program.

What Drug Testing Records Must NYC Employers Keep Confidential?
Drug testing records are inherently sensitive and must be treated as confidential from the moment they are created. Confidential drug testing records include far more than just test results—the entire constellation of documentation associated with a drug testing program must be protected:
- Pre-employment drug test results (positive, negative, and refused)
- Random, post-accident, and reasonable suspicion drug test results
- Medical Review Officer (MRO) reports and communications
- Return-to-duty test results and follow-up testing documentation
- Employee notifications and consent forms related to testing
- Chain-of-custody forms and specimen collection documentation
- Drug-free workplace policy acknowledgments and training records related to testing
- Employee disclosures of prescription medication use made in connection with testing
Each of these document types can contain highly sensitive personal and medical information. Under the ADA, medical information collected from employees must be kept separate from general personnel files and protected from unauthorized disclosure. Drug test results that implicate protected medical conditions—including the use of legally prescribed medications—fall squarely within this framework.
Federal Requirements for Drug Testing Record Retention and Disposal
For employers subject to Department of Transportation (DOT) drug testing regulations—which apply to safety-sensitive industries including transportation, aviation, pipeline, and transit—the retention and disposal requirements are highly specific. DOT-regulated employers must retain drug and alcohol testing records for specified periods depending on the type of record:
- Positive Drug Test Results and Test Refusals: Must be retained for five years
- Alcohol Test Results of 0.02 BAC or Greater: Must be retained for five years
- Negative and Cancelled Drug Test Results: Must be retained for one year
- Documentation of Rehabilitation: Must be retained for five years
- Alcohol Test Results Below 0.02 BAC: Must be retained for one year
After these retention periods have expired, drug testing records must be destroyed in a manner that prevents unauthorized reconstruction. For non-DOT employers, there is no single federal statute that mandates specific retention periods, but a combination of EEOC guidance, ADA requirements, and state employment laws typically supports retaining drug testing records for the duration of employment plus two to three years.

New York City-Specific Considerations for Drug Testing Records
New York City has enacted some of the country’s most progressive cannabis and employee privacy laws, which add important layers to the drug testing record compliance picture. Under New York State’s Marijuana Regulation and Taxation Act (MRTA), employers are generally prohibited from taking adverse employment actions against employees based solely on lawful off-duty cannabis use. This creates unique complications for drug testing programs and the records they generate.
NYC employers must be particularly careful about how they handle and dispose of positive cannabis test results that may not legitimately support adverse employment action under the MRTA. Records documenting testing outcomes that led to adverse actions—or that may be the subject of future litigation about the legitimacy of those actions—require especially careful retention and disposal planning. Key NYC-specific considerations include:
- Cannabis test results that do not support adverse action under the MRTA should be segregated and retained per applicable guidance, then destroyed through certified shredding when eligible
- Records related to terminated employees who test positive for cannabis require careful review before destruction to assess potential litigation hold obligations
- NYC’s strong employee privacy culture means courts and enforcement agencies scrutinize drug testing record handling practices closely
- Consult employment counsel before implementing a drug testing record destruction schedule to ensure compliance with current NYC and NYS employment law
Best Practices for Drug Testing Record Disposal
Given the sensitivity and legal significance of drug testing records, their disposal warrants the same level of care as medical records. Here are best practices for NYC employers:
- Maintain Separate, Locked Files: Drug testing records should be stored in dedicated, locked files or cabinets—never in general personnel files. Access should be restricted to HR personnel with a legitimate need to know.
- Implement a Written Retention Schedule: Create a written policy specifying retention periods for each category of drug testing record, consistent with applicable federal and state requirements.
- Conduct Annual Destruction Reviews: At least annually, review drug testing records to identify those that have reached the end of their retention period and are eligible for destruction.
- Use Certified Shredding for All Destruction: Partner with a certified shredding provider for all drug testing record destruction. Never place these records in general recycling or unsecured trash.
- Obtain and Retain Certificate of Destruction: For every shredding event involving drug testing records, obtain a Certificate of Destruction and retain it as a permanent compliance record.
