Does CBD oil show in a drug test in Australia?

Whether you’re already using CBD or just getting into it, you might be worried about how it will show up on a roadside drug test. We understand – after all CBD oil is a cannabis-derived product.

Will CBD Show Up On Drug Tests?

The simple answer to the question of whether or not it will show up on a drug test is “no”. Let’s dive into the details.

How long does CBD oil stay in the blood system?

Many individuals are concerned about whether CBD oil can show up in a drug test, especially in Australia where drug testing is a common practice. So, does CBD oil show in a drug test in Australia?

The detection of CBD in the bloodstream for up to five hours is a common concern for individuals. It is essential to note that like most medicines, CBD and its byproducts are only detectable in the blood for short durations. Therefore, a standard blood test may not be effective in detecting the presence of CBD or its components in the body.

When it comes to drug testing, blood testing is typically preferred when there is a suspicion that the individual is actively under the influence of drugs. However, for specifically testing CBD, other methods may be more effective. These alternative methods can provide more accurate results in determining whether CBD oil shows up in a drug test.

In conclusion, although CBD oil may be detectable in the bloodstream for a short period, its presence is not commonly tested in standard drug screenings. Therefore, the likelihood of CBD showing up in a drug test is relatively low, particularly in Australia. However, it is essential to consider the specific policies and regulations surrounding drug testing in your region.

But first, let’s talk about how the body processes CBD. CBD absorption refers to “the transportation of the unmetabolized drug from the site of administration to the body circulation system”2. When CBD reaches the blood, it is transported to different parts of the body and interacts with both CBD receptors within the endocannabinoid system3 and non-cannabinoid receptors such as serotonin receptors4.

It is these interactions that allow CBD to have the beneficial effects we are now familiar with, on both the body and the brain. The potency of CBD oil depends highly on the method of administration. When it is ingested, CBD travels through our digestive system to the stomach. From there, it is transported to the liver, where the metabolization process begins5. A lot of CBD is lost during this process before the rest of it enters the bloodstream, which is why CBD edibles and CBD oil administered orally are not the most effective methods of taking CBD.

The same cannot be said about taking CBD oil sublingually. If you allow the mucus membrane under your tongue to absorb the CBD oil, it can bypass the digestive system and enter your bloodstream directly. This increases the amount of CBD present in your body and thus, its potency. For this reason, sublingual CBD drops are much more effective than other methods of administration.

How long does it take for CBD to leave your system?

The noticeable effects of CBD occur within 15 minutes to one hour after taking it, depending on the dosage and method of administration, and they can last anywhere between four to six hours.

As we said above, drugs are quickly metabolized and eliminated from the bloodstream. It does not take more than 5 hours for CBD to leave your circulatory system, but it can be found in your urine for longer periods of time, usually between one to several days.

Like most other substances, CBD can also be found in your hair follicles. These are tube-shaped formations found in the first two layers of the scalp. Hair follicle tests are highly effective drug test alternatives because substances can be present here for up to 90 days6.

How to get CBD out of your body fast

It is important to note that in Australia, many people wonder, “does CBD oil show in a drug test?” Unlike THC, the other well-known compound found in cannabis, CBD does not have psychoactive effects and does not cause the typical “high” associated with cannabis use. However, if you are concerned about CBD showing up in a drug test, here are a few remedies to consider:

  • Drink lots of water to increase the frequency of urination. This will help get the CBD out of your body through your bladder.
  • Try exercising for 30 minutes to one hour to promote sweating. Sweat contains toxins and other substances that your body wants to eliminate, so working up a good sweat will help lessen the amount of CBD in your body.
  • Eat foods that are high in fiber. Fiber will stimulate bowel movements and more quickly eliminate external substances from your system.

Can you drive with CBD oil in your system?

Driving while under the influence of any drugs, whether they are illicit or not, is prohibited in all states and territories throughout Australia. This raises the question: can you drive with CBD oil in your system? The answer is simply yes! Unlike THC, which is a psychoactive component of cannabis that can impair cognitive abilities and motor skills, CBD does not have any psychoactive effects. Therefore, it will not cause any impairment to your driving abilities and is safe for you to take before operating a motor vehicle. It is also completely legal in Australia! So if you’re feeling anxious or stressed out, taking some CBD oil may be one way to help ease your mind before getting behind the wheel.

Roadside drug testing Australia

Roadside drug testing is becoming increasingly common, with police using infrared cameras to detect people who may be driving under the influence of drugs or alcohol. The National Road Safety Council predicts that by 2020 roadside drug testing will be as common in Australia as breathalyzer tests.

In order to carry out roadside drug testing, police must first suspect a driver of being impaired by drugs or alcohol. If they do, they can administer a saliva test and if the driver tests positive for drugs, they will be arrested and taken to a police station for further medical testing7.

For drivers who are suspected of driving under the influence of illegal substances such as cannabis, methamphetamine, or cocaine, two-step roadside drug testing is used. The first step is to test the driver’s saliva using a swab. If this tests positive, then a second confirmatory blood or urine sample will be taken at a police station.

CBD oil does not show up in drug tests and is considered a non-intoxicating substance in Australia. Many people wonder, “Does CBD show up in a drug test?” The answer is no. CBD is not typically tested for in standard drug tests. However, it is essential to note that THC, another compound found in hemp products, may be present. Consequently, individuals who have consumed CBD products may test positive for THC during roadside drug testing and face potential consequences. Therefore, while CBD itself does not show up in drug tests, it is crucial to be mindful of the presence of THC in CBD products and the potential for positive test results.

The most important step to take in avoiding this is to look for high-quality, laboratory-tested CBD products that are THC free. This will ensure that drivers remain free from the risk of accidentally driving with THC in their system.

Can CBD be found in a hair drug test?

The hair follicle test is a highly effective option when you want to find traces of drugs long after they were taken. As we mentioned above, hair follicles absorb substances that can be detected for up to 90 days.

CBD, however, will not show up in a hair follicle test unless the test is specifically designed to look for it. A specific CBd hair follicle test is highly unlikely, and will not have damaging consequences because CBD is legal and non-intoxicating. That means that even if CBD is, in some way, found in your hair follicles, you will not get in trouble for it.

Can you bring CBD oil into Australia?

Transporting CBD oil into Australia is legal as long as the quantity does not exceed three months’ supply. Patients who bring CBD oil into Australia are also required to show a prescription, identification, and a note from their doctor proving the need to use CBD oil8, as well as declare the products at border control.

Getting a CBD prescription is not an easy task; fortunately, there are easier ways to gain access to CBD oil. You can find high quality, laboratory-tested CBD oil available for purchase online, without a prescription. It’s similar to over-the-counter CBD oil (which is not yet available in Australia), with the bonus of getting it delivered to your front door. Here’s a helpful list with the top CBD oils we’ve found online, tested by us for quality and effectiveness.
