Mouth Swab Drug Test and Breath Testing for Alcohol – What it Involves

More institutions or workplaces are conducting drug and alcohol testing to minimise safety risks associated with substance use. Similarly, law enforcement places more checkpoints or random tests to check the drivers’ conditions. This is because substance impairment is one of the leading causes of workplace or road accidents. Consuming drugs or alcohol has adverse effects on health and affects safety. It impairs the senses and motor skills necessary for driving or operating machinery. Therefore, drug and drink driving is a criminal offence in Australia with heavy penalties. Roadside screening involves a mouth swab drug test and breath testing for alcohol to check for impairment. 

What do a mouth swab drug test and breath testing for alcohol involve? It is typical for roadside screening to conduct a mouth swab test to check for drugs in the system. Likewise, a breath test through a police breathalyser can detect alcohol and determine the level of alcohol intoxication. Police use these tests because they are non-invasive and give rapid results. As a result, many individuals check their alcohol levels before driving to ensure they are within the legal limit. Many people use personal devices from Breathalysers Australia to test their Blood Alcohol Content (BAC). It also helps them monitor the decline of their BAC after alcohol consumption to be fit for driving. 

Mouth Swab Drug Test and Breath Test: How They are Conducted

There are several procedures to check for alcohol and drugs in the system. Most workplaces use urine tests to detect drugs and breathalysers for alcohol. These methods are cost-efficient in monitoring workplace impairment. However, a urine test is not suitable for all instances. For example, police officers use a mouth swab drug test instead of urine samples because it is easier, faster, and less intrusive. Similarly, an alcohol breath test does not require a laboratory examination. These methods have the following functions: 

  • Mouth swab – also called an oral fluid or saliva test. It involves swabbing the insides of the cheek. A trained or licensed collector uses a stick with a sponge or absorbent pad on one end. Then, the sample is analysed on-site or properly secured for laboratory examination.
  • Breath test – testing agencies or law enforcement use a breathalyser to trace the presence of alcohol in the breath. For example, a test administrator may ask someone to provide a sample breath by blowing into the device’s mouthpiece. If the breathalyser detects alcohol, it displays the BAC results or the amount of alcohol on the screen. 


Mouth Swab Drug Test: What Can it Detect?

When a person takes drugs, the body absorbs, distributes, and metabolises them. The bloodstream absorbs the drugs and circulates them to different body organs. Additionally, the body breaks down drug molecules and excretes them through breath, urine, or saliva. Therefore, drug molecules end up in the mouth for a definite period. A mouth swab drug test is a simple and non-invasive procedure to determine recent drug use. It is a useful diagnostic alternative for urine tests because they are convenient. Moreover, a saliva test can trace drugs within 5 to 24 hours. However, substances are detectable for longer periods for people who frequently take them. A multi-panel mouth swab test can detect the following substances:

  • Amphetamines
  • Methamphetamine
  • Barbiturates
  • Ecstasy or MDMA
  • Benzodiazepines
  • Cannabis (THC)
  • Phencyclidine (PCP)
  • Cocaine

Alcohol Testing with Breathalysers

A mouth swab drug test and alcohol breath test are the most convenient methods. They can be done in full view of the test administrator; therefore, they are difficult to tamper with. For example, police officers ensure you do not put anything in your mouth that may lead to invalid test results. Furthermore, a breathalyser is a portable device utilising sensor technology to estimate a person’s BAC level. Law enforcement, laboratories, and workplaces use breathalysers with fuel cell sensors to accurately measure the BAC. Fuel cell breathalysers undergo an electrochemical process to oxidise alcohol in the breath. Additionally, they are specific to ethanol and do not react with other substances. Thus, it is less likely to produce false positives. 

Like the mouth swab drug test, a breathalyser gives rapid results. It can detect alcohol for 12 to 24 hours based on the amount consumed. Moreover, fuel cell breathalysers remain consistent despite repeat testings and have a longer recalibration period than a standard semiconductor breathalyser. Therefore, they are cost-efficient devices for professional settings. Similarly, individuals who rely on accuracy may get a pro-grade breathalyser for personal use. Breathalysers Australia offers various alcohol testers with fuel cell sensors for dependable BAC readings. The BACtrack fuel cell breathalysers use the same technology law enforcement uses in roadside screenings. You may get a personal breathalyser depending on your specific needs. 


Advantages of Mouth Swab Drug Tests and Breathalyser Tests

A mouth swab drug test and breathalyser devices are cost-effective in delivering reliable results in a short time. They are also inexpensive compared to laboratory services. Roadside screenings use these methods because they are handy and easily conducted. Likewise, some workplaces use a mouth swab test as an alternative for urine drug screening. Meanwhile, a breathalyser is the most efficient for screening alcohol. These methods have the following advantages:

  • Easy collection – they are non-invasive and do not have privacy issues like a urine test. 
  • Fast results – collecting oral fluid and waiting for the results take five minutes to perform. On the other hand, the BACtrack breathalysers can process the sample and deliver the results in 10 to 15 seconds.
  • Lesser risk of tampering with the test – the tests are facilitated in front of a police officer or technician. Therefore, there is less probability of a person interfering with the results.
  • Effective and accurate – mouth swab tests are as effective as urine drug tests. In addition, pro-grade breathalysers are alcohol-sensitive devices that can accurately measure the BAC. 

Getting a Professional Breathalyser at Breathalysers Australia

Many people consume alcohol in moderate amounts to help them relax or unwind. However, minimal alcohol in the system can still pose safety risks. Therefore, many people use personal devices to monitor their alcohol levels. Fortunately, you may get a pro-grade breathalyser from Breathalysers Australia to help moderate the alcohol intake. The BACtrack fuel cell breathalysers have police-grade accuracy, which is valuable in checking the BAC. It keeps people from exceeding the legal alcohol limit and avoids drink driving. For instance, the BACtrack S80 Pro is ideal for a quick breath test. You may also get a device with a Bluetooth connection like the Mobile Pro to view your BAC results directly from a smartphone. Additionally, it prevents unnecessary problems when a police officer randomly conducts a breathalyser or mouth swab drug test.


A mouth swab drug test and breath test for alcohol are efficient methods to check for substance use or impairment. They are ideal for detecting recent exposure to alcohol or illicit drugs. Moreover, more companies or individuals ensure safety through saliva and breathalyser tests because of their ease of use and simple collection procedure. Personal devices like the BACtrack breathalysers can also help you make informed safety decisions. Breathalysers Australia offers a wide range of reliable devices for efficient BAC monitoring.
