How Long Does Delta 9 Stay In Your System?

How Long Does Delta 9 Stay In Your System?

Almost every THC user has this question in mind, “how long does delta 9 stay in the system.” The answer to this question depends on different factors. But how your metabolism reacts with this compound is crucial. Let’s understand the human body's metabolic process to digest and clear Delta 9 from your system.

Explanation of the Body's Metabolic Process of Delta-9 THC

Delta-9-tetrahydrocannabinol (Delta-9 THC) is the main psychoactive compound in cannabis. Here's a simplified explanation of how it's processed in the body:

1. Absorption

Methods of Consumption:

Smoking/Vaping: Delta-9 THC enters the bloodstream quickly through the lungs, with effects felt within minutes.

Edibles/Tinctures: Delta-9 THC is absorbed more slowly through the digestive system, with effects kicking in after 30 minutes to 2 hours.

2. Distribution

Once Delta-9 THC enters the bloodstream, it spreads throughout the body. The compound is attracted to fatty tissues and organs such as the brain, liver, and lungs, so its effects are strongly felt in these areas.

3. Metabolism

The liver is the main organ that breaks down Delta-9 THC. This happens in two steps:

Step 1: Initial Breakdown

Liver Enzymes: Special enzymes in the liver (mainly from the CYP450 family) transform Delta-9 THC into 11-hydroxy-THC (11-OH-THC), which is also psychoactive [1].

Step 2: Further Breakdown

Formation of THC-COOH: 11-OH-THC is then broken down into 11-nor-9-carboxy-THC (THC-COOH), which is not psychoactive.

Conjugation: THC-COOH combines with glucuronic acid to form a compound that is easier for the body to get rid of [2].

4. Excretion

The body gets rid of Delta-9 THC and its metabolites mainly through urine and feces.


THC-COOH: This is the main compound tested for in urine drug tests. It can be detected for days or even weeks after using cannabis, depending on how much and how often you use it.


A significant amount of THC and its breakdown products are also expelled in feces.

Factors Influencing Metabolism

Several factors affect how quickly Delta-9 THC is processed and eliminated:

Frequency of Use:

Regular users accumulate more THC in their bodies, so it takes longer to clear out.

Individual Metabolism:

People have different metabolic rates that affect how quickly they break down THC.

Body Fat:

THC is stored in fat, so people with higher body fat may retain THC longer.

Overall Health:

Healthier individuals, especially those with good liver function, may process THC more efficiently.

Does Delta 9 Show Up On A Drug Test?

Does Delta 9 Show Up On A Drug Test?

The body eliminates eighty to ninety percent of the metabolite within five days, based on research. However, regular users may take longer to eliminate THC from their system. Here are the approximate time periods for a positive test result based on the presence of Delta 9:

  • Single Use: Up to Three Days
  • Moderate Use (four times per week): Approximately 5 days
  • Heavy Use (everyday): Up to ten days
  • Excessive, Regular Use: Up to 30 days

Therefore there are chances that some drug tests will detect Delta 9 in your system.

Types of Delta 9 THC Drug Tests

Delta-9 THC can be detected in your system via various drug tests. Each method has different detection windows and procedures. Let's understand which test is most effective and how long these tests can detect THC in your body.

Urine Tests

It is the most common method for detecting Delta-9 THC. This is due to their non-invasive nature, ease of administration, and cost-effectiveness.

The Detection Window

  • For occasional users, this test can detect THC in urine for about 3 to 7 days after consumption.
  • For regular or heavy users, the detection window can extend up to 30 days or more as the THC remains in fatty tissues for a long time.

Blood Tests

  • Blood tests are not as common as Urine tests because they are more Invasive and costly.
  • However, they provide a more immediate measure of recent cannabis use.

Detection Window

  • For occasional users, Delta-9 THC is typically detectable in the blood for up to 24 hours after use.
  • For chronic users, THC can be detected in the blood for several days as it accumulates in the body and is released back into the bloodstream over time.

Saliva Tests

  • Saliva tests are mostly used by law enforcement for roadside testing to determine if a driver is currently under the influence of cannabis.
  • They are quick and non-invasive in nature.

Detection Window

Saliva tests can detect Delta-9 THC for about 1 to 3 days after use. These tests are effective for identifying recent cannabis consumption.

Hair Tests

  • Hair tests for THC are less common as they are expensive and require longer processing time.
  • However, it is a highly sensitive test and can provide a comprehensive history of drug use.
  • They are often used in situations requiring long-term substance use analysis, such as in certain employment screenings or forensic investigations.

Detection Window:

Hair tests can detect Delta-9 THC use for up to 90 days or even longer. This is because THC metabolites are deposited in the hair follicles from the bloodstream and remain as the hair grows.

Understanding the different types of Delta-9 THC drug tests is crucial for individuals who may be subject to testing, whether for employment, legal, or personal reasons. Each testing method has its own detection window and level of invasiveness, making it important to know which test might be used and how long Delta-9 THC can be detected in one's system.

What are the legal thresholds for THC levels in drug tests?

In the U.S., federal workplace drug tests typically have a threshold of 50 ng/mL for initial urine tests and 15 ng/mL for confirmatory tests [3]. Some states have limits for driving under the influence, like 5 ng/mL of THC in blood. In sports, the World Anti-Doping Agency sets a limit of 150 ng/mL for THC-COOH in urine during in-competition testing. Thresholds vary by context and jurisdiction to ensure safety and compliance.

Can You Get Through Delta 9 Drug Test With Negative Result?

While there is no well researched/studied method to avoid positives in your Delta 9 drug test. However abstraing the consumption completely at least 8 months prior to the drug test can get you a negative result. But this method also depends on some factors like how much D9 you used, the usage frequency, the products you used, and how long you took THC before abstaining. Below are some of the methods to get Delta-9 out of your system quickly.

How To Get Delta 9 Out Of Your System Fast?

To clear Delta-9 THC from your system quickly, several methods may help you speed up the detoxification process. While no method can guarantee complete and immediate elimination, these tips support your body's natural detoxification functions.


Staying well-hydrated helps your body flush out toxins, including Delta-9 THC. Aim to drink at least 8-10 glasses of water a day.

Caution: Avoid overhydration, as it can lead to water intoxication and dilute your urine too much, which might be flagged in a drug test.

Eat a Balanced Diet

Focus on a diet rich in fruits, vegetables, lean proteins, and whole grains. These foods support liver function and overall health.

High-Fiber Foods: Fiber helps move toxins through your digestive system. Include foods like beans, lentils, and leafy greens.

Avoid Fatty Foods

Since Delta-9 THC is stored in fat cells, reducing fat intake can help minimize the storage of THC in your body.


Cardiovascular exercises such as running, cycling, or swimming can boost your metabolism and help burn fat, speeding up the elimination of THC from fat cells.

Strength Training: Building muscle mass can also increase your metabolic rate, aiding in faster detoxification.


Ensure you get 7-9 hours of sleep per night. Proper sleep supports your body's natural detoxification processes and overall health.

Detox Products

There are various detox kits and supplements available that claim to speed up the elimination of Delta-9 THC from your system. These often contain herbs, vitamins, and minerals to support liver function and increase urination.

While some users report success, results can vary. It's essential to research and choose reputable products.

Summing up on how long does delta 9 stay in the system?

Understanding the metabolic process of Delta-9 THC and the various drug testing methods is vital for cannabis users, especially those who may face drug tests for legal or professional reasons. Responsible use is essential to avoid any potential negative consequences. Always use good quality products. Being aware of the duration Delta-9 THC can stay in your system and how to manage its presence can help you make informed decisions about your cannabis use.
