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. If you know you have group activities for addiction recovery an upcoming drug test, not all hope is lost. Given the current detection windows for standard cannabis tests, it’s likely you will be able to pass a urine test as long as you are not an extremely heavy user and are given sufficient advanced notice. But if your employer tests you regularly and without prior notification, perhaps it wasn’t a dream job after all.
How long does marijuana stay in your system? What weed-users should know
- This is because THC is stored in fat, and if you exercise and that fat breaks down, THC is released back into your system.
- A 2020 review found that THC was still detected in the oral fluid of frequent smokers 72 hours after use.
- Even among people of the same gender and age, individual lifestyle choices such as level of exercise and eating habits may also affect the amount of time required to pass a drug test.
- Hair tests tend to have the longest detection window, capable of registering the levels ofa non-intoxicating THC metabolite called 11-nor-delta9-caboxy-THC (THC-COOH) up to 90 days after cessation.
Research has shown that this testing system is 97.5% accurate at this cut off (this means that more than 97 people will accurately test positive out of 100 people who have used marijuana in the past 24 hours). Similar to blood tests, most saliva tests can only detect marijuana within 24 hours of use. Exercise will help you break down the fat cells that are holding onto the THC so it’s good to do some working out in the weeks before the test. However, you can’t just hop on the treadmill 24 hours before you go in for the urinalysis.
How long do tests detect weed?
The most common ways marijuana can be tested for is in urine, saliva, blood, or hair. Most testing practices look for the presence of THCCOOH which has a much longer half-life (the time it takes for 50% of the substance to be excreted) than delta-9 THC. The half-life of THCCOOH is hours in occasional users compared to 3-13 days in regular users. We publish material that is researched, cited, edited and reviewed by licensed medical professionals.

THC metabolites stay in the body for at least 1–30 days after use. Regular cannabis users may have elevated THC levels even after a period of abstinence. Cannabis metabolites usually have a shorter window of detection in blood or saliva samples. Many who are facing a drug test but are unwilling to fully give up cannabis turn to synthetic cannabinoids in the hopes of cheating traditional tests.
Those with higher body fat will metabolize weed slower than those with less fat, according to Medical News Today. Hydrating more than normal won’t necessarily affect the results of a drug test, but dehydration may increase THC concentration. Regular exercise won’t change a drug test’s results, but exercising right before a drug test may increase the chance of a positive test. 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. Flegel also notes that he often sees cases where individuals fluctuate between positive and negative tests for marijuana over a period of time.
When we consume cannabis, its cannabinoids and other byproducts remain detectable in our bodies well after the buzz wears off. Marijuana is solution-focused therapy techniques pdf only detectable in oral fluids for about 24 hours. However, it can be detectable even longer in people who have used marijuana for extended periods of time. Depending on the type of blood test, marijuana can be detected anywhere from 3.5 hours up to 7 days.
Higher doses and more frequent use tend to increase the amount of time it takes to eliminate THC and its metabolites from your system. Saliva testing has a short window of detection and, in some cases, may detect same-day cannabis use. Others who continue to smoke cannabis may attempt to tamper with their urine, adding chemicals such as pyridinium chlorochromate or peroxidase that eliminate THC-COOH in the sample. Most testing agencies, however, will screen for these compounds and being caught is often just as bad, if not worse, than a positive test. Like hair tests, these urine screens do not directly measure the amount of THC present, but rather the levels of the metabolite THC-COOH.
The Macujo Method is considered 90% effective to pass a drug test but can be pretty costly. Edibles won’t usually last in your system if you use marijuana once in a while. But you should still stay away from edibles between one and three days from your test. Testing for THC and its metabolites can only determine whether cannabis has been used within a given window of time. THC and its metabolites may stay in your system anywhere from several days to several months after you last use cannabis.
The evaluation consists of 11 yes or no questions that are intended to be used as xanax vs ambien an informational tool to assess the severity and probability of a marijuana use disorder. The test is free, confidential, and no personal information is needed to receive the result. When you use marijuana, your liver breaks it down into metabolites. About 20% of the metabolites leave your body through urine, while the other 80% are removed as feces. Only urine tests designed to detect THC metabolites will show cannabis use.
