Setting Up a Drug-Free Workplace

Whether you have 2 employees or 200, a drug-free workplace program protects your business, your team, and your liability. Here's the framework.

01

Written Policy First

Before you test a single employee, you need a written drug-free workplace policy. It defines what you test for, when, consequences, and employee rights. Without it, a positive result can be challenged. California employers are strongly encouraged to have one in writing — DOT employers are federally required to.

02

Define When You Test

Most programs include some combination of: pre-employment, random, post-accident, and reasonable suspicion testing. Each serves a different purpose. Not every employer needs all four — we'll help you figure out what makes sense for your business when you call.

03

Communicate the Policy

Employees and applicants must be informed of your drug testing policy before any test is administered. For most programs, this means including it in your offer letters, employee handbook, and having employees sign an acknowledgment. Documented notification protects you legally.

04

Choose the Right Test

Non-DOT employers can choose their panel — 5-panel covers the most common substances, 10-panel adds prescription drug abuse coverage. DOT employers have no choice — the federal 5-panel is mandated. See our test comparison table below.

05

Train Your Supervisors

For reasonable suspicion testing to hold up, supervisors must be trained to recognize and document signs of impairment. Without proper training and documentation, a reasonable suspicion test can be legally challenged. DOT requires 60 minutes of alcohol and 60 minutes of drug training per supervisor.

06

Policy Guidance

Drug-Free Workplace Policy Checklist

A legally defensible drug-free workplace policy should cover the following elements. Use this as a starting point — consult your HR or legal counsel to finalize your specific policy.

Your Written Policy Should Include

Check these items off before your first test. Missing any of these can create legal exposure.

  • Purpose and scope of the policy
  • Which employees are covered (all, safety-sensitive only, etc.)
  • Substances tested (panels and cutoff levels)
  • All testing occasions (pre-employment, random, post-accident, cause)
  • Collection procedures and testing methodology
  • Consequences of a positive, refusal, or adulteration
  • Prescription medication disclosure procedure
  • Employee rights and confidentiality protections
  • Rehabilitation/EAP options (if applicable)
  • Return-to-duty requirements after positive result
  • Supervisor reasonable suspicion training requirement
  • Employee acknowledgment and signature line
