What Oregon Employers Should Know About the Standard Pre-Employment Drug Test

So, you’re running a business in Oregon and thinking about adding drug testing to your hiring process. Do you know what that involves? 

A standard pre-employment drug test in Oregon isn’t complicated, but it does come with a few responsibilities. Getting the facts straight can save you time and avoid some major problems.

This guide will walk you through the basics: what the test includes, how it’s done, what your legal rights are as an employer in Oregon, and how to set up a process that’s both fair and efficient.

What Is a Standard Pre-Employment Drug Test?

A standard drug test is usually a 5-panel urine test that checks for the most commonly used substances. This includes:

• Marijuana (THC)
• Cocaine
• Opiates
• Amphetamines
• Phencyclidine (PCP)

Some companies choose to test for more, like benzodiazepines or barbiturates, but these five are the starting point.

The test itself is super simple. The candidate provides a sample (usually urine) which is either tested immediately or sent to a lab. If everything is negative, you’ll get results fast. If something looks off, the sample will get sent for further review.

Why Oregon Employers Use Drug Testing

Drug testing before hiring helps protect your business. It shows you’re serious about safety, productivity, and keeping a reliable team.

Here are a few reasons employers choose to test:

• Safety: Especially in jobs that involve driving, machinery, or physical work, even small mistakes can have big consequences. Testing helps you screen for risks.
• Attendance and performance: People struggling with substance use may have more absences or trouble focusing. A drug test can give you an early warning.
• Insurance savings: Some insurance plans offer better rates to companies that test workers as part of a written policy.
• Workplace standards: Having a drug-free workplace policy sets the tone and creates clear expectations.

Is Drug Testing Legal in Oregon?

Yes. Employers in Oregon are allowed to require a drug test before hiring someone, as long as it’s done fairly and with notice. That means you need to:

• Let applicants know that passing the test is part of getting the job
• Use the same policy for all applicants for the same role

Oregon has legalized both recreational and medical marijuana. But that doesn’t mean you have to allow it at your workplace. You can still test for THC and make hiring decisions based on the results.

There are a few exceptions and added rules for union positions or jobs covered by federal law, so it’s always smart to double-check if your industry falls into one of those categories.

What to Expect From the Testing Process

The process starts with scheduling. Candidates can go to a clinic, or you can arrange for on-site testing if that works better for you.

Here’s what happens step-by-step:

1. Candidate gets instructions: This includes where to go, what to bring, and any rules (like not drinking too much water beforehand).
2. Sample is collected: Most standard tests use urine, but some may use oral fluid or hair depending on your preferences.
3. Initial screen: If you’re using a rapid test, results can be ready in 15 to 30 minutes. If it’s a lab test, it usually takes 1 to 3 days.
4. Confirmation testing (if needed): If the result is positive or unclear, the sample is sent to a certified lab for more testing.
5. Results are reviewed and sent to you: You’ll get a clear report showing whether the candidate passed or failed.

Throughout the process, it’s important to treat candidates respectfully. A drug test can be a sensitive topic, and how you handle it reflects on your business.

Should You Use a 5-Panel or Something More?

The 5-panel test is the most common because it’s fast, affordable, and covers a wide range of substances. But depending on your industry or concerns, you might want a more detailed screen.

A 10-panel test, for example, includes:

• Everything in the 5-panel
• Benzodiazepines (like Valium or Xanax)
• Barbiturates
• Methadone
• Propoxyphene
• Methaqualone

For most workplaces, a 5-panel is probably enough. If you work in healthcare, transportation, or another industry where more substances are a concern, it may be worth going with a broader option.

Handling Results the Right Way

Once you receive the results, you need a clear policy in place. What happens if someone fails? What if they refuse the test?

Many companies include this information in their offer letters or employee handbooks. Having a policy ahead of time prevents confusion or arguments later.

Also, make sure any test failures are kept private. Only people who absolutely need to know should see the results.

How to Make Testing Part of a Smooth Hiring Process

Drug testing doesn’t have to slow things down. Here are some tips to keep the process moving:

• Work with a reliable testing provider that communicates clearly and returns results quickly
• Schedule tests early in the week to avoid weekend delays
• Keep your candidates informed so they know what to expect and don’t miss appointments
• Use mobile testing if your team works in the field or at remote job sites
• Review your policy every year to make sure it still fits your business needs and follows the law
