This means we can tell whether there was an increase, decrease, or constant usage of weed. After that, the concentrations of THC in the oral fluid were deficient, almost not detected. There was research where participants were required to smoke cigarettes containing mg of THC. There was another study involving pilots who smoked a cannabis cigarette containing 20 mg of THC. According to the mentioned research, it took four 4 for effect to wear off after smoking and via injection.
Detection Window in Urine
The peak concentration was within 2 hours and then gradually reduced below one mg/L after ~22 hours. When THC gets into the liver, it is metabolized to 11-OH-THC, THCCOOH, and some other metabolites. The degree of “high” was lower, and it took about 6 hours for the effects to wear off. There THC is metabolized in 2 phases and then excreted via urine and feces.

Impact of Edibles on Detection
They’ll only differ in the onset of effect, which we’ll discuss later.

How long does weed stay in your system? When different drug tests can detect cannabis
So a hair test likely won’t detect a smoke session from two days ago. But if you were using cannabis a month or two ago, it could very well show up. Hair tests can potentially detect THC use how long does weed stay in your system for up to 90 days (around three months) after your last use. In fact, 90 days is the typical timeframe labs look at, because an average person’s hair grows about 0.5 inches per month.
- The liver plays a crucial role in metabolizing THC into active compounds like 11-hydroxy-THC, which are eventually broken down into carboxy-THC—a non-psychoactive metabolite used in drug testing.
- Even if you’ve only had a few puffs, like from a vape pen or joint, you might still test positive depending on the timing of the test.
Habits for Proper Mental Health
For occasional users, THC metabolites may only be detectable in urine for a few days, but for chronic users, these compounds can remain in your system for up to 30 days or more. Blood tests are more likely to detect recent use, while hair tests can reveal a much longer history of cannabis consumption. The frequency of use and your individual body composition, including your BMI, play a significant role in how long these metabolites remain in your system and are detectable via drug testing.
This THC detox calculator or drug test calculator uses up-to-date data from medical research and scientific studies to emulate how marijuana is metabolized in the body. For a drug test to be negative, the body must eliminate THC from the system as well as metabolic chemicals that have links to THC. People with faster metabolisms typically eliminate THC more quickly than those with slower metabolisms. THC and its metabolites may stay in your system anywhere from several days to several months after you last use cannabis. Researchers don’t know how long the effects of chronic cannabis use last. Higher doses and more frequent use tend to increase the amount of time it takes to eliminate THC and its metabolites from your system.
What if I use edibles?
At Leafy Mate, we encourage you to explore these various methods and find what works best for you. Paul Jannetto, Ph.D., underscores the need to differentiate between new and residual marijuana consumption and to calculate the carboxy-THC to creatinine ratio. THC’s fat-soluble nature allows it to stay in the system longer than many other drugs. It doesn’t dissolve quickly in water, and instead, lingers in adipose tissue.
- The only real way to be sure there’s no THC in your system is to abstain from using marijuana products.
- However, CBD is not regulated by the Food and Drug Administration (FDA), which means it could contain small amounts of THC.
- Exercising regularly (although not right before a test), healthy eating and hydration can all help, but they won’t substantially change your THC levels.
- Individuals using this over-hydration method also often take a vitamin B-12 supplement to turn their urine more yellow, making it appear less dilute.
The test is cheap, and results can be ready in as little as 10 minutes. These tests look for traces of THC or its metabolites in a sample of urine. How long they can detect THC after the last use depends on how much weed a person consumes. It is actually believed cannabis has the longest detection window in hair.
