The detection period for light or moderate use of marijuana is closer to the average duration. You could get a positive urine test result within about four to seven days. THC metabolites stay in the body for at least 1–30 days after last use. Regular cannabis users may have elevated THC levels even after a period of abstinence. Consequently, Cary offers some shorter estimates of detection windows that he believes would be reasonable to expect given an individual’s frequency of usage and the sensitivity of the particular urine test.

Eventually, THC and its metabolites are excreted in urine and stool. The more THC metabolites you have in your body, the longer this process takes. THC is absorbed by the bloodstream when you smoke or ingest cannabis. THC can enter the saliva through exposure to secondhand cannabis smoke.

Blood tests

Head to our Just Curious section to see what else we can answer for you. The most influential factor in getting weed out of your system is time, Healthline says. Using cannabis during pregnancy can negatively affect fetal growth and development.

  1. Although these levels drop significantly after a few days, there are other means of determining recent usage.
  2. Exercising and having good hydration are two ways to boost metabolism.
  3. How long a THC high lasts and how long THC stays in your system are two very different things.
  4. THC and its metabolites may stay in your system anywhere from several days to several months after you last use cannabis.

Ultimately, there is no definitive method to get cannabis out of the body faster. However, strategies that may help to remove cannabis from the body quicker involve breaking down body fat cells, speeding are psychedelics addictive up THC metabolism in the liver, and removing THC metabolites from the intestines. An older study notes a slight increase in THC levels following exercise in people who regularly use cannabis.

What’s the detection window for different cannabis drug tests?

However, there is no reliable way to speed up the metabolism and excretion of THC. The most important factor is the time from the last exposure to the testing time. Exercise will not significantly change the rate at which the body metabolizes THC. Once dmt: side effects withdrawal overdose and treatment 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.

Hair tests can detect THC metabolites for as long as 90 days; however, these tests can be inaccurate or misleading when detecting recent cannabis consumption in light consumers. cognitive behavioral therapy for relapse prevention Having one or two edibles or smoking once a day may not affect your results in a hair test. It takes time for THC to be stored in your hair follicles and build up.

As the body stores THC in fat cells, regular exercise may help to break fat cells down and release THC into the blood for further excretion. However, while exercise might help the body metabolize more THC, exercising too near to a test may also cause a positive result due to having THC in the bloodstream. This means that a person who smokes several times over several days has consumed a higher THC dose than someone who smokes once, so they are more likely to test positive. A blood test may detect marijuana in blood more quickly than a urine test and up to two days from consumption.

However, in cases of heavy use, it’s been detected 30 days after last use. Drug tests for cannabis measure THC and its by-products, or metabolites. These metabolites remain in your system long after weed’s effects have worn off. Millions of employees and potential employees are drug tested every year in the United States and elsewhere. They are measured for drug metabolites in their urine, blood, hair, saliva, breath, sweat, and even fingernails.

However, it's not as commonly used because THC can't be detected in blood for as long as it can be detected in urine. Tetrahydrocannabinol (THC) is the main component responsible for the euphoric high you get when using marijuana. Over time, THC stored in your body’s tissues and organs is released back into the bloodstream.

How long does THC stay in your urine?

The most common cutoff for most marijuana urine tests is 50 ng/mL, but cutoffs can be as low as 15ng/mL and as high as 100ng/mL—each of which result in widely different detection windows. Detectable amounts of tetrahydrocannabinol (THC) may remain in the body for days or even weeks after use. Upon consumption of marijuana, THC is absorbed and stored by various body tissues and organs. The by-products formed by the breakdown are immediately cleared via urine. In a chronic user, the excretion rate of THC through urine is less, so it builds up in the liver.

A 2017 study published in Drug and Alcohol Review analyzed hair samples collected from 136 subjects and found detectable levels of THC in 77% of chronic consumers and 39% of light consumers. However, there's mounting evidence that hair follicle drug testing cannot detect cannabis accurately. Excessive exercise in an attempt to burn fat, since THC is stored in fat, is not unheard of either. The bottom line is that there is no way to guarantee a negative test result for THC, but an understanding of the detection windows may help you better plan your next job change. After entering and circulating through the body, some THC will reach hair follicles through small blood vessels where small amounts are deposited into the growing hair.

As such, exercise right before a drug test may increase the likelihood of a positive test result. Typically, weed will remain longer in hair and can be detectable for up to 90 days from the day of use. Tests can detect weed for up to 30 days in your urine, up to 24 hours in your saliva, and up to 12 hours in your blood.

Marijuana preparations are usually smoked in pipes, joints, or water pipes (bongs). Since most CBD products, even isolates, contain some THC, there is a risk of testing positive for THC metabolites, especially with regular use. THC metabolites can be detected in saliva for one to three days after occasional consumption or a month if you consume regularly. With edibles or tinctures, THC will enter the bloodstream through the walls of the stomach and intestines, traveling directly to the liver. The liver breaks down much of the THC to a cousin compound called 11-hydroxy-THC, which also enters the bloodstream. THC and 11-hydroxy-THC are detectable in the bloodstream after cannabis is ingested through the digestive tract.

It’s also important to remember that “occasional” and “chronic” cannabis users each represent opposite sides of the usage spectrum, and most consumers would likely fall somewhere in the middle. Marijuana, also known as weed, pot, or ganja, is a medicinal plant of the cannabis family. It contains a psychoactive compound known as tetrahydrocannabinol (THC) that has major intoxicating effects. The leaves, seeds, stems, or roots, are mainly used for intoxication purposes.
