How long does THC remain in the body?

THC: a molecule that's the talk of the town


THC (tetrahydrocannabinol), the main psychoactive component of cannabis, fascinates as much as it intrigues. Whether in THC candies, THC cookies or THC puffs, this molecule is increasingly consumed in a variety of forms, often for recreational purposes. But it can also pose a problem, particularly when it comes to drug testing.
Remember the story of Michael Phelps, the famous Olympic swimmer. In 2009, a photo of him using a bong went viral, reigniting the debate on cannabis in sport. Although he was not tested at the time, many wondered how long THC could have remained detectable in his system. So, how long does this molecule remain in the body? Here's everything you need to know.

THC in saliva: the express test

Saliva screening is one of the most commonly used methods for detecting recent consumption.

  • Detection time: Generally between 24 and 48 hours after last consumption.
  • Influencing factors : Frequency of consumption (occasional or regular) and type of product consumed (THC candies or THC puffs, for example).
  • Why this test? Rapid and non-invasive, it is often used during roadside checks.

Note: Brushing your teeth or using mouthwash does not remove THC from saliva. It takes time for the body to metabolize the substance. THC Kleaner can be used, but may be difficult to obtain.

THC in the blood: a shorter window of opportunity

THC is detectable in blood for a shorter period than in urine or hair.

  • Detection time :
    • For a single consumption: about 12 to 24 hours.
    • For regular consumers: up to 7 days.
  • Why this test? It's an accurate way of determining whether someone is under the immediate influence of cannabis, especially in the event of an accident or a test at work.

Please note: THC is fat-soluble, which means it binds to fat. It can therefore be released into the bloodstream during intense physical effort, even after several days.

THC in urine: the classic method

Urine tests are the most frequently used, as they offer a wider detection window.

  • Detection time :
    • Single use: 3 to 7 days.
    • Regular use: up to 30 days or more.
  • Why this test? Simple and inexpensive, it is the preferred choice for screening in the workplace or in legal proceedings.

Interesting fact: The more regular the consumption, the more metabolites (such as THC-COOH) accumulate, prolonging their detection.

THC in hair: consumption history

Hair tests can be used to trace cannabis consumption over a long period.

  • Detection time: Up to 90 days, or longer depending on hair length.
  • Why this test? Used for in-depth surveys, it provides a detailed consumption history.

Limitation: These tests do not detect recent consumption, but rather traces accumulated over time.

Factors influencing detection time

Several factors determine how long THC remains in the body:

  • Frequency and quantity of consumption: The more you consume, the longer it will stay.
  • Metabolism: A fast metabolism eliminates THC more quickly.
  • Product type: High-fat THC candies or THC cookies can prolong the presence of THC in the body.
  • Fat mass: Since THC is stored in fat, people with a higher percentage of fat can retain it longer.

How to speed up THC elimination?

If you're preparing for a drug test, there's no quick fix for THC. However, here are a few tips:

  • Hydration: Drinking water can help dilute metabolites in the urine, but does not eliminate them.
  • Exercise: Increased physical activity can help release THC from fat, but it can also temporarily increase its presence in the blood.
  • Balanced diet: A healthy diet can support the metabolism.

Warning: the "detox products" often offered online lack scientific proof and can be detected in certain tests.

Conclusion: patience is the key

THC can remain in the body from a few hours to several months, depending on the type of test and consumption. Whether you're a fan of THC candy or prefer THC puffs, it's best to know your habits and the possible implications.
And if you find yourself in a tricky situation, remember that even the greatest personalities, like Michael Phelps, have faced these questions. In the end, the most important thing is to consume responsibly.
