What is Delta-9 THC?

One important cannabinoid that is prevalent in cannabis is Delta-9 THC. As a result, extraction is typically straightforward and inexpensive. It usually comes from marijuana plants in particular. 

You can get a higher sense of wellness, relaxation, or calmness by taking Delta-9 THC. Since delta-9 tetrahydrocannabinol has a higher potency than delta-8 and makes up the majority of the naturally occurring THC in the cannabis plant, people smoke it more frequently. 

Numerous hemp businesses are selling "compliant delta-9" products that have less than 0.3% THC and are therefore permitted by the 2018 Agriculture Improvement Act (Farm Bill).

In essence, the 2018 Farm Bill allowed cannabis-based products with a dry weight THC content of less than 0.3%. Officially, anything that fits this definition is referred to as "hemp."

For example, delta-9 gummies with 10mg of THC gives most users a pleasant high experience. A 10mg THC candy must have a total weight greater than 3.33 grams in order to be considered legal. This is a bit larger than typical gummies, but it's a small price to pay for THC that is legal, and several businesses are now producing these bigger, compliant candies!

Can 0.3% of Delta-9 THC Show Up on a Drug Test?

Yes. There is a possibility that a drug test could find Delta-9 THC in your system if you recently took any sort of THC. However, it may be different for every person depending on the exam and how frequently you use cannabis. 

In most cases, a urine drug test searches for the metabolites that break down Delta-9 THC. Also, urine testing can be used to identify THC-COOH, the main inactive metabolite of Delta-9 THC. After ingesting THC a urine test can identify these metabolites for some time because our body retains them in our fat cells.

It depends on how much you ingest because legal CBD products include 0.3% THC, which is unlikely to stay in your system for very long. For instance, a 10ml bottle of CBD oil may contain up to 30mg of THC. Therefore, 3mg of THC is equivalent to 1ml.

Though it isn’t common for 0.3% THC to stay in your system, regular ingestion of 1ml+ of CBD oil containing about 0.3% THC could possibly increase the risk of not passing a drug test. Your body would need more than a week (176 hours) to get rid of 87.5% of the THC metabolites in your system because it has a half-life of 44 hours in urine.

Delta-9 Detection in Drug Tests

Using Delta 9 once or twice will probably get cleared from your system quickly.  THC won't be noticeable for the vast majority of users for two to four days. On the other hand, regular users may have measurable Delta 9 THC levels for 30 days or longer.

Even if you eat legal Delta-9 gummies, you might risk failing a drug test. However, the THC is most likely gone from your urine in four days or less if you only took Delta-9 once. If you regularly use it, it may take a month or longer for your system to be clean enough for a drug test. Avoiding all Delta-9 items is the simplest approach to ensure you pass a drug test if you are aware you must do so. 

According to studies, your body eliminates 80–90% of the metabolite in five days. The amount of time it takes for THC to exit your system can vary depending on how often you use marijuana. An overview of how long Delta-9 can stay in your system before causing a positive test result is below:

  • One-time Use = Up to 3 days later
  • Occasional Use (4 times per week) = Up to 5 days later
  • Heavy Use (daily) = Up to 10 days later
  • Chronic Use = Up to 30 days later

*These times are estimates that can help you determine how long the metabolites may stay in urine.

Additionally, the chances you will pass a drug test after ingesting Delta-9 THC depends on a number of variables. For example:


As we get older, it takes longer for our bodies to metabolize substances, including THC.

Consumption Method

Various Delta-9 products remain in the body for varying lengths of time. Compared to smoking THC, Delta-9 Edibles take your body longer to break down. The time it takes for your body to metabolize the two is normally one day.

Frequency of Use

As previously mentioned, THC stays in your system longer the more of it you consume. Your body keeps more metabolites in your system for a longer time if you take larger and more regular doses. Occasional users will notice that THC metabolites are eliminated from the body more quickly than chronic users.

Body Fat Content

The THC metabolites are kept in your fat cells because they are lipid-soluble. Theoretically, you release THC more quickly if you have less body fat.

So, depending on these four factors, you can take into account what will affect passing your drug test.

Can CBD Show Up on a Drug Test?

A drug test shouldn't reveal the presence of CBD. But, the primary active component of marijuana, delta-9-tetrahydrocannabinol (THC), is present in small concentrations in many CBD products. THC will appear on a drug test if there is enough of it present. This indicates that consuming CBD could, in very rare circumstances, result in a positive drug test.

A 2019 study published in Sports, issued a warning about the unsettling amount of CBD items for sale in Germany that have the equivalent of 2.5mg of THC per daily dose. According to the study's authors, athletes who take these products may test positive for THC at a certain level of usage.

When using full-spectrum CBD oil, the only THC metabolites to be concerned about are the trace amounts. Other research has shown issues with incorrectly labeled CBD products, indicating a significant risk that the product you purchase might contain too much THC. Even though it contains less THC than the legal limit of 0.3%, frequent or excessive use may guarantee that your body still contains detectable levels of THC-COOH metabolites.

Additionally, many run the risk of getting false positives when taking CBD products because of frequent use. If your concern is to keep THC levels low, consider sticking to broad-spectrum CBD isolate products.


For whatever reason you might want to ingest products that have THC, it’s essential to know the exact amount. Whether or not the labels actually state the correct amount will depend on the brand. Stick to reliable brands and there will likely be less problems. 

Now, knowing how long does 0.3% THC stay in your system, is important for anyone required to take a drug test. If you happen to take larger amounts of THC, you run the chances of failing your drug test. To make sure that you will pass carefully consider each product you put into your body and how much THC it may have.

Having worked in the drug testing industry, I’m more than aware of how long THC, and other drugs, stay in our systems. THC is possibly one of the least harmful and yet can stay in the system for months, even years, after stopping heavy use.


Hhhhmmm… all this makes sense. The older we get, the longer THC takes to be absorbed in the body.

This is a great article to read and be well-informed about! As we take CBD, in a regular basis. It’s great to know this stuff before having a medical test. Thanks for sharing this with us!

It’s hard to know these days what you’re getting when you purchase a CBD product. Thanks for the helpful information.


I didn’t realize there were so many variances to how long it can stay in your system. It’s definitely important to know if you have a known test coming up.
