How Long Do Edibles Stay in Your System?
For many Canadians, understanding how long cannabis edibles stay in the body is a key concern, especially when it comes to drug testing and responsible use. The answer isn’t straightforward, as it depends on several factors, including the type of edible consumed, your metabolism, and overall body chemistry. Unlike smoking, where the effects of THC are felt almost immediately, edibles take longer to kick in because the THC is absorbed through the digestive system.
This in-depth guide breaks down the science behind how your body processes THC from gummies and other edibles, what affects how long it stays detectable, and how various drug tests, like urine, saliva, and blood tests, measure its presence.
The Journey of THC Through the Human Body
When you ingest an edible, the delta-9 THC it contains begins a unique journey. Instead of being absorbed directly into the blood vessels from the lungs, it travels to the stomach and then to the liver. Here, a process called first-pass metabolism occurs, converting the delta-9 THC into a more potent metabolite known as 11-hydroxy THC. This metabolite is largely responsible for the stronger, longer-lasting psychoactive effects associated with edibles.
After this conversion, the 11-hydroxy THC and other marijuana metabolites are distributed throughout the body, interacting with your endocannabinoid system before being stored in fat cells and eventually eliminated. This slower, multi-step process is a key reason why drug testing detection times for edibles can be significantly longer.
How Long Do Edibles Stay in Your System?
The length of time THC from edibles stays in your system varies widely and depends on several individual and product-specific factors. Unlike smoking, edibles are processed through the digestive system and liver, producing longer-lasting effects and potentially longer detection windows.
For occasional users, THC metabolites may be detectable in urine for 3 to 5 days after consumption. However, this can vary depending on:
- Your metabolism
- Body fat percentage (THC is stored in fat cells)
- Dosage and potency of the edible
- Frequency of use
For regular or heavy users, THC can remain detectable in urine for up to 30 days or more. In contrast, hair follicle tests can detect THC for up to 90 days, regardless of consumption method. Blood and saliva tests have much shorter windows, typically a few hours to a few days, depending on use.
5 Key Factors That Influence Detection Times
A person’s metabolism rate is a major determinant of how quickly marijuana metabolites are cleared. This, along with other variables, means that two people can consume the exact same edible and have vastly different detection windows. Here are some of the key factors that influence how long edible detection lasts per person:
1. Body Composition & Metabolism
Your body fat percentage directly impacts how long THC lingers. Since THC is a fat-soluble compound, it is stored in fat cells. Individuals with a higher body fat percentage have more storage for these marijuana metabolites, which are then released slowly over time. Similarly, a faster metabolism rate will naturally help your body excrete these compounds more quickly than someone with a slower metabolism.
2. Frequency and Quantity of Use
A one-time, low-dose edible will typically clear from the body much faster than regular, heavy use. With frequent consumption, THC and its metabolites accumulate in the body’s fat cells, gradually releasing over time. This buildup can significantly extend the detection window, sometimes lasting weeks or even months after the last use, especially in chronic users.
3. Edible Potency and Type
The amount of THC in a THC gummy or other edible product is directly proportional to how long it will stay in your system. A higher dose means more delta-9 THC and subsequently more 11-hydroxy THC for your body to process. Additionally, the type of edible can have an impact; some products, like CBD edibles, contain only trace amounts of THC, while others are designed for high potency, with a direct effect on detection times.
4. Hydration and Lifestyle
While staying hydrated and living an active lifestyle can support your metabolism, it is important to be realistic about their effects. While these practices can help, they are not a guaranteed method for shorter detection times and passing a drug test. The fundamental science of how THC is stored in fat cells remains the primary factor.
5. Drug Interactions
Certain medications or drug interactions can affect your liver metabolism, which could potentially alter how your body processes THC. It is important to be aware of any medications that may interfere with this process, as it can impact the total duration of THC in your system.

The Different Types of Marijuana Drug Tests Explained
For anyone facing a drug test, understanding the method of drug screening is essential. Each type has a unique detection window, making some more suitable for certain situations than others.
Urine Testing: The Standard Drug Test
Urine testing is the most common method for drug screening. It is non-invasive and provides a reliable detection window for recent drug usage. For a casual user, marijuana metabolites can be detectable for 3-5 days. However, for a regular user, this can be anywhere from 10 days to over a month. Urine tests are the primary tool used by employers for pre-employment drug testing (Huestis et al., 1995).
Hair Testing: The Long-Term Look at Drug Usage
Hair testing or a hair follicle test offers the longest detection window, often up to 90 days. This is because marijuana metabolites from the bloodstream are absorbed by the hair follicles as they grow. A hair follicles test can provide a long-term history of drug usage and is generally more difficult to tamper with than a urine test. Due to this wide detection window, hair testing is often used for long-term monitoring (Cuypers et al., 2018).
Blood Testing: For Immediate Detection
Blood testing for THC has the shortest detection window, usually only a few hours. This is because THC is quickly absorbed by blood vessels and distributed to fat cells after consumption. Blood testing is typically used in situations where recent impairment is suspected, such as a traffic stop or an accident investigation (Newmeyer et al., 2017).
Expert Tips for Safe Cannabis Consumption
While cannabis edibles offer a convenient and discreet way to consume, their unique first-pass metabolism means they require a cautious approach. To ensure a safe and positive experience, it’s essential to understand proper dosing and safe consumption practices.
By following these tips, you can better control your experience and avoid overconsumption:
- Start with a Low Dose: Begin with a small amount of THC, such as 2.5 to 5 milligrams. This is a crucial step for beginners, allowing you to gauge your body’s individual reaction without the risk of an overwhelming psychoactive cannabinoid effect.
- Be Patient: After consuming an edible, wait at least two hours before considering another dose. The delayed onset of psychoactive effects can lead to taking too much, causing an unpleasant and prolonged experience that could have been easily avoided with patience.
- Choose a Safe Environment: Consume THC gummies or other edibles in a comfortable and familiar setting. Being in a safe, relaxed space with people you trust is key to managing any unexpected feelings and ensuring a calm, positive experience.
- Stay Hydrated and Nourished: Have water and some food on hand. Staying hydrated can help mitigate a dry mouth, while having a light snack beforehand can sometimes help to slow down liver metabolism, leading to a smoother onset of effects.
- Store Edibles Securely: Always store your marijuana edibles in clearly labelled, child-resistant containers. Many edibles look like regular snacks or candies, posing a significant risk of accidental ingestion by children or pets.
