Workplace Drug and Alcohol Testing Purpose, Procedure and Types

Australia Drug Testing

In today’s competitive job market, workplace drug and alcohol testing has become a common practice. Employers have a vested interest in maintaining a safe and productive work environment, and one way to achieve this is through drug and alcohol testing. In this article, you will explore the purpose, procedure, and various types of workplace drug testing. We’ll also touch on the important aspect of workplace drug testing laws to ensure you have all the information you need.

Workplace Drug Testing Laws

Before we dive into the basics of workplace drug and alcohol testing, let’s first understand the legal framework that governs it. Workplace drug testing is delivered in both federal and non-federal offices. And it must always comply with local, state, and federal laws. These workplace drug testing laws set the guidelines for how and when drug testing can be carried out.

Workplace Drug and Alcohol Testing Procedure

Purpose of Drug Testing:

Workplace drug and alcohol testing serves multiple purposes, making it a critical part of many drug-free workplace programs. The primary reasons for carrying out drug tests in the workplace include:

  1. Before Hiring

Before welcoming a new employee into the fold, employers may require drug testing. This helps ensure that new hires are drug-free and capable of carrying out their job responsibilities effectively and safely.

  1. During Employment

Even after an employee is hired, employers may periodically or randomly require drug testing. This ongoing monitoring helps maintain a drug-free environment and can act as a deterrent to drug use among employees.

  1. Suspected Drug Use

If an employer observes signs and symptoms of drug use in an employee, they may request a drug test. These signs could include changes in behaviour, job performance, or physical appearance.

  1. After an Accident

In cases where an employee is involved in an accident or incident at work, drug testing may be necessary. This helps determine if drug use played a role in the incident and can assist in determining liability.

  1. Diagnosis, Treatment, and Monitoring

Outside the workplace, drug limits and testing are also used for the diagnosis, treatment, and monitoring of alcohol use disorder and substance use disorder. This is important for healthcare providers to assess treatment adherence, monitor abstinence, and detect early relapse.

Workplace Drug and Alcohol Testing Procedure:

Typically, these tests are done either at the workplace or a clinic, depending on the employer’s preference and local workplace drug testing laws. A trained collector is responsible for carrying out the test, which may involve collecting samples like urine, blood, hair, breath, or sweat. The choice of sample depends on the type of drugs you are testing for and the detection window.

Types of Workplace Drug and Alcohol Testing

Now that we’ve covered the purposes of workplace drug and alcohol testing, let’s explore the different types of drug tests available, each with its unique quality and advantages, all contributing to the benefits of drug and alcohol testing:

  1. Urine Drug Testing

Urine drug testing is the most common type of drug test. It requires a urine sample. Primarily, you can use it to detect a wide range of substances, including alcohol, amphetamines, benzodiazepines, opiates/opioids, cocaine, and marijuana (THC).

  1. Blood Drug Testing

Blood drug testing measures the actual amount of drugs or alcohol in the blood at the time of testing. It has a shorter detection period, making it a better indicator of recent consumption.

  1. Hair Follicle Drug Testing

This test requires collecting a hair sample, which provides information on substance use over time. Scalp hair has a detection window of three months while slower-growing body hair can detect substance use over up to 12 months. This test can detect substances such as cocaine, phencyclidine (PCP), amphetamines, opioids, and MDMA.

  1. Breath Drug Testing

Primarily used to detect recent alcohol use, breath drug testing results in a breath alcohol concentration (BAC). You can also use it to estimate a person’s blood alcohol content and, more recently, detect other substances like cocaine, marijuana, benzodiazepines, amphetamines, opioids, methadone, and buprenorphine.

  1. Sweat Drug Testing

Sweat drug testing requires wearing an absorbent pad on the skin, which you then collect and test after a specific time frame. It provides information on the amount of a substance consumed over the period the pad was worn, with a detection window ranging from hours to weeks.

Understanding Drug Test Results

When looking at drug test results, it’s important to consider a few key points:

Positive Drug Test Result: A positive result indicates the presence of a detectable amount of a substance during a specific window of time. However, it does not necessarily mean the person is currently intoxicated or has a substance use disorder. Positive results on initial drug tests sometimes require confirmation through a different test. However, drug tests certified to Australian Standards reduce the likelihood of receiving a false-positive result.

Negative Drug Test Result: Conversely, a negative result means that the tested substance was not detected. This could be due to insufficient levels for detection or the substance use falling outside the detection window. To enhance the efficiency of your drug testing procedure, it is important to employ a drug testing device that has been duly verified to meet Australian Standards.

Additionally, false-positive results can occur due to medications or certain foods. While false-negative results can be affected by sample collection issues, attempts to falsify the test or the limitations of the specific workplace drug and alcohol testing being used. However, drug testing kits certified to Australian Standards minimise the chances of false results, while delivering more accurate tests.


Workplace drug and alcohol testing plays a vital role in maintaining a safe and productive work environment. Understanding workplace drug and alcohol testing procedures, purpose, and types of drug tests is important for a smooth and lawful process. 

Whether you’re an employer aiming to ensure a drug-free workplace or an employee subject to testing, knowing the ins and outs of workplace drug and alcohol testing can help you navigate this essential aspect of modern employment. By staying informed and compliant, you contribute to a healthier and safer workplace for all.
