How to Start a Drug-Free Workplace Testing Program

Published August 25, 2026

A step-by-step framework for employers building a workplace drug-testing program, from policy design to collection logistics and recordkeeping.

A good workplace testing program begins before the first test is ordered. Employers should define the purpose, coverage, procedures, and responsibilities so employees and managers know what to expect.

Write the policy first

Define which employees or job categories are covered, what testing situations are included, how employees are notified, and what happens after a result. Employers should have the policy reviewed for compliance with applicable law and contractual requirements.

Separate DOT and Non-DOT processes

If your workforce includes DOT-regulated employees, keep those testing requirements distinct from the company’s general workplace program. The paperwork, procedures, and employer obligations may differ.

Choose testing events

Your policy may address:

  • Pre-employment
  • Random testing
  • Post-accident testing
  • Reasonable suspicion
  • Return-to-work or follow-up processes

Only include testing practices that are appropriate for your organization and permitted under applicable requirements.

Train the people who administer the policy

Managers should know who can order a test, who to contact, how to document a situation, and how to protect confidential information.

Set up collection logistics

Choose how employees will be scheduled, where they will test, and how completion will be tracked. A repeatable process is especially useful for employers with multiple locations or frequent hiring.
