How Long Do Edibles Stay in Your System?

Edibles can be detected in your system usually for 1-3 days, even though the effects might wear off in a few hours. However, some tests can detect THC in your body even if you have consumed edibles within 90 days.

There are specific factors determining how long the THC in edibles may stay in your system. In this article, you will find the exact period for every test that’s usually done to detect marijuana usage.

Understanding Edibles

Edibles encompass a diverse range of food products infused with marijuana or cannabis, such as brownies, candies, gummies, chocolates, and beverages.

The psychoactive effects of edibles are attributed to tetrahydrocannabinol (THC), the active ingredient in marijuana.

Notably, ingesting edibles differs significantly from smoking in terms of onset time, duration, and how the body processes THC.

Factors That Affect Detection Time

A variety of factors influence how long edibles remain in an individual’s system. Dosage, frequency of usage, and individual metabolism are all important factors to consider.

Higher THC concentrations in edibles may lengthen detection times, and repeated usage may result in THC buildup in the body.

Furthermore, those with higher metabolisms tend to excrete THC more quickly, affecting the length of its retention in the system.


The amount of THC in your edible has a big impact on how long it stays detectable in your system. Higher dosages produce higher THC and metabolite concentrations, expanding the standard detection window.

For example, taking a single dose of an edible containing 10mg of THC can last for four to twelve hours.

Expect a more prolonged effect if the dosage is increased to around 20mg or two servings, with results potentially lasting longer than 12 hours. Higher THC concentrations need more time to process and remove, adding to a longer stay in the system.


Individuals who regularly use cannabis may develop a tolerance to THC. Higher tolerance levels are associated with faster THC metabolism, reducing the overall time it stays in the system. Those accustomed to cannabis use can experience a swifter elimination of THC compared to occasional users.


The diversity in individual metabolic rates plays a pivotal role in how quickly the body processes and eliminates THC. Factors such as genetics, age, body composition, and overall health contribute to variations in metabolism.

People with higher metabolisms might break down THC faster, resulting in a smaller detection window. Individuals with slower metabolisms, on the other hand, may retain traces of THC for a more extended period. The effectiveness of the elimination process is also influenced by liver function, which is a significant participant in THC metabolism.

Frequency of Use

Consistent and frequent ingestion of cannabinoids disrupts the body’s ability to eliminate THC efficiently. Repeated use without sufficient intervals for THC clearance leads to the accumulation of THC metabolites.

Unlike occasional users who might experience a shorter detection window, individuals consuming edibles regularly may exhibit traces of THC for an extended period due to the continuous introduction of THC into the system.

Body Fat Percentage

THC is fat-soluble, meaning it is stored in body fat. Individuals with higher body fat percentages may retain THC in their bodies for a more prolonged duration compared to those with lower body fat percentages.

Essentially, it takes longer for individuals with higher body fat to break down the THC stored in their bodies, contributing to an extended detection window.

Testing Methods and Detection Time

The efficiency of drug testing in identifying marijuana or its metabolites is heavily dependent on the testing method used. Each approach has its own set of pros and limitations, as well as different detection windows, which adds to the difficulty of correctly determining how long edibles remain in the system.

Blood Test

One of the most direct approaches for detecting recent marijuana usage is blood testing. However, because of the narrow detection window, they are less popular than other testing procedures.

THC is detectable in the circulation for just a short time after intake, often 1-2 days. While blood tests offer immediate results, they are less effective for identifying longer-term cannabis usage.

Saliva Test

Saliva testing is gaining popularity for its non-invasive nature and ability to detect recent drug use. Following the consumption of edibles, THC can be detected in saliva for a period of 1 to 2 days. This method is particularly useful for identifying recent marijuana use and is commonly employed in roadside testing due to its simplicity and immediacy.

Urine Test

Urine tests are the most often used type of drug testing and offer a wider detection window than blood and saliva tests. THC metabolites can be seen in urine for up to three days after taking edibles. Urine tests are routinely utilized. However, they only reveal prior usage.

Hair Follicle Test

Hair follicle tests are the most in-depth detection approach, providing information about a person’s drug use throughout time. THC can be identified in hair follicles for up to 90 days or longer in edibles. Because of its invasiveness and the possibility of false positives, this approach is less commonly used. It does, however, give a detailed summary of a person’s cannabis consumption behaviors.

Effects of Edibles on Drug Testing

Understanding how edibles impact drug testing is crucial, as their detection can influence legal, professional, and personal consequences. The timeframe for THC detection in different tests is as follows:

  • Blood Test: Detectable for 1-2 days.
  • Saliva Test: Detectable for 1-2 days.
  • Urine Test: Detectable for 1-3 days.
  • Hair Follicle Test: Detectable for up to 90 days.

Given the potential for extended detection times, individuals who consume edibles should be aware of the legal and professional implications of drug tests.


Finally, how long edibles stay in your system is impacted by a variety of factors, including dose, frequency of usage, and individual metabolism. Individuals who may be subjected to drug testing must understand the testing procedures and their associated detection timeframes.

As the landscape of cannabis regulation develops, understanding the long-term consequences of edibles becomes critical in making responsible and educated decisions about their intake.
