If you’re seeking accurate and reliable methods to conduct workplace drug testing, saliva drug testing kits offer a convenient and effective solution.

In this article, we’ll delve into how saliva drug tests work, their accuracy and reliability, where to buy them in Australia, and their various applications, including workplace drug screening, roadside testing, and pre-employment use.

How Saliva Drug Tests Work

Saliva drug testing is a non-invasive method that can detect the presence of drugs and their metabolites in an individual’s saliva. Unlike urine, blood, or hair testing, which may require specialised collection procedures and equipment, saliva drug tests are relatively straightforward and convenient.

A. Detection Windows for Different Drugs

Saliva drug tests have different detection windows for various drugs. These windows refer to the period during which drugs can be detected in the saliva after use. The drug detection times vary based on factors such as the drug’s half-life, frequency of use, and individual metabolism. Here are some common drugs and their typical detection windows in saliva drug testing1:

  • Marijuana (THC): Detectable for 1-3 days after use, or up to 30 days with frequent use.
  • Cocaine: Detectable for up to 1-2 days after use.
  • Amphetamines (including methamphetamine): Detectable for up to 4 days after use.
  • Opiates (e.g., heroin, opium, tramadol): Detectable for up to 2 days after use.
  • Codeine and Morphine:  Detectable for up to 4 days after use.
  • Benzodiazepines: Detectable for up to 3 days after use.
  • MDMA (Ecstasy or Molly): Detectable for up to 2 days after use.

It’s essential to note that detection times can vary based on the specific test kit’s sensitivity and the amount of drug used.

B. Saliva Sample Collection

Saliva sample collection is simple and quick. A collection sponge is placed inside the mouth, usually under the tongue or against the cheek, to collect a saliva sample. This process is non-invasive and can be conducted in a supervised or unsupervised manner, depending on the testing situation.

C. Reading the Results of Saliva Drug Testing Kits

Interpreting the results of a saliva drug test is usually straightforward. The test device will display clear indicators for positive or negative results. However, it’s important to follow the manufacturer’s instructions carefully to ensure accurate readings.

How Accurate Are Saliva Tests?

Saliva drug tests, when performed correctly and with reliable testing kits, are highly accurate. They can provide timely information about recent drug use, making them particularly valuable in certain situations.

For instance:

Post-Accident Investigations: In situations where accidents occur in the workplace or on the roads, determining if drug use played a role is crucial for legal and liability purposes. Saliva drug tests can provide timely information about drug use, helping investigators understand whether the presence of drugs contributed to the incident.

Substance Abuse Treatment Programs: For individuals undergoing substance abuse treatment, saliva drug tests can be vital in monitoring compliance with treatment plans. Regular testing helps healthcare professionals track progress and ensure patients are staying drug-free during their recovery journey.

Random Drug Testing in Schools: Some educational institutions may implement random drug testing programs to deter drug use among students and maintain a drug-free learning environment. Saliva drug tests provide a practical and efficient method for conducting such testing.

Factors That Affect Accuracy of Saliva Drug Testing Kits


Several factors can influence the accuracy of saliva drug tests:

  • The quality and sensitivity of the testing kit used.
  • Proper sample collection and handling procedures.
  • Adherence to the test’s expiration date and storage conditions.

By ensuring you use quality, verified saliva drug testing kits and following proper procedures, you can enhance the accuracy and reliability of your test results.

Pros and Cons Vs. Urine, Blood, and Hair Testing

Saliva drug testing offers several advantages over other testing methods:

  • Non-invasive and easier to administer compared to blood tests.
  • Shorter detection windows make it ideal for detecting recent drug use.
  • Can be performed on-site without the need for specialised equipment.
  • Saliva tests offer quicker results compared to hair testing, which may take days to yield results.
  • Saliva drug tests are less susceptible to adulteration or tampering compared to urine tests.

However, it’s essential to consider the specific requirements of your testing situation when choosing the appropriate workplace drug testing method.

Cons of saliva drug testing:

  • Shorter detection windows compared to urine, blood, and hair tests, making them less suitable for detecting drug use beyond a few days.
  • Lower sensitivity for certain drugs compared to urine or blood tests, potentially leading to false negatives.
  • Due to the shorter detection window, saliva tests are less ideal for long-term drug monitoring compared to hair tests.
  • Unlike urine or blood tests, saliva tests may not detect drug metabolites, which can be essential for identifying specific drugs and their breakdown products.
