Before you discreetly type, ‘How long does marijuana stay in your urine’ into the search bar, awaiting that upcoming drug test, allow us to present a concise and practical guide. It’s all about unraveling the mysteries of cannabis in your urine and sprinkling in some tips for a faster detox. Urine testing is done through an immunoassay-based how long does weed stay in your system test which employs a competitive binding mechanism. Immunoassays are quick and accurate tests used to signal the presence of a certain substance through its reaction with an antibody. In the United States, the most common cut-off for a positive urine test is 50 nanograms of THC metabolite per milliliter (ng/mL) of urine.

If your home THC drug test shows that your urine tests positive for THC, you can buy yourself some time by drinking a ton of water. Having a large amount of liquid in your system will dilute your urine. In turn, your urine sample will essentially be water, and your test may be considered inconclusive. This means you will have to retake the test at a later date, giving your body extra time to flush out THC.

How long does THC stay in the body?

This is because blood tests have a narrow window of time to detect marijuana use. These tests typically only work within three to four hours when a person uses marijuana, which is when THC is still in the bloodstream. Those with higher body fat will metabolize weed slower than those with less fat, according to Medical News Today. Women generally have more body fat than men, lowering their metabolism rate.

In jurisdictions where cannabis is illegal, oral fluid may be used for roadside testing. Exercise will not significantly change the rate at which the body metabolizes THC. How “high” a person feels is also not a reliable measure, because numerous factors other than THC dose can intensify or weaken this feeling.

Syva’s innovation made widespread drug screening possible at a more affordable price, and it also extended the detection window by a considerable length of time. It did so by focusing on 9-carboxy-THC, which is the main metabolite of cannabis’s primary intoxicating ingredient (tetrahydrocannabinol, or THC) that is excreted in urine. Since these metabolites stay in the body for much longer than THC itself, the new test was more adept at catching cannabis users after a prolonged period of time. Depending on what type of screening you’re having, THC tests can scan for metabolites in the urine, skin, hair, nails, blood, or even saliva. Remember that the duration of treatment can also depend on various factors, but what you do will show you how long the marijuana stays in your system. While you can have a good idea of how long the weed needs to stay in the system, you should also look at the various test scenarios you may encounter.

Research from 2017 estimates a detection window for a single cannabis cigarette of about 3 days. Oral swab tests are a quick, simple method of detecting recent marijuana use—within the past few days, especially the last 24 hours. Marijuana is broken down by the body into metabolites, which are detectable on drug tests and can remain in your system even longer than THC. This may be true with long-term marijuana use because THC can be stored in fat cells and accumulate.

We’re basing our data on an average American man, who according to the CDC, weighs about 200lbs. Using cannabis during pregnancy can negatively affect fetal growth and development. Once THC has entered your system, your body needs time to break it down. Exercising, eating a balanced diet, and staying hydrated may help, but not drastically. Cannabis that’s ingested may remain in your system slightly longer than cannabis that’s smoked. More potent cannabis, which is higher in THC, may also stay in your system for longer.

Your biology and how you use THC may affect how long it stays in your system. The same applies to delta-8 THC and delta-10 THC products, which can cause you to test positive for drug use. Eventually, your body eliminates THC metabolites via your urine and stool. Cannabis concentrates contain potent amounts of THC, the chemical in cannabis that makes you feel intoxicated. From ancient empires to today’s tech-driven world, humanity’s dance with cannabis is an age-old tango. As we better understand cannabis and its interactions, it’s essential to consider these varied timelines in both personal and professional contexts.

And for a regular user of edibles, the detox period stretches to 21 days. If we run the numbers for them, we find that weed can be detected in their system for up to 18 days. Here’s the chart showing how long a joint stays in https://ecosoberhouse.com/ the system of our skinny person. This is because body weight isn’t the key factor – even a skinny person has enough body fat to store all the THC they ingest. Another supplement to consider on the day of the test is creatine.

• Smoking or vaping may lead to quicker absorption and elimination of THC compared to ingestion, which involves a more extended metabolic process.
• For example, if you smoked just once, you will be able to pass the test within a few days.
• In the liver, THC is metabolized into THC-COOH-glucuronide, which is excreted via urine and stool.
• The last century brought along the dawn of drug laws which demanded detection methods.
