For occasional users, marijuana may only stay in their system for up to 3 days after consumption. In contrast, regular or heavy users may test positive for up to 30 days after how long does weed stay in your system the last use. A 2009 study published in the journal Addiction tested THC blood concentration levels in 25 frequent, long-term cannabis users over seven days of abstinence.
As a 2021 study pointed out, most urine tests — particularly at-home drug tests — can’t distinguish between delta-8 and delta-9 THC. This can cause legal difficulties for people who legally use delta-8 THC where delta-9 THC is illegal. Whether THC will be detected in a drug test is highly variable from person to person, and it depends on the frequency and amount of marijuana use. In heavy users, THC could stay in your system for a month or more.

Some cannabis detox remedies and kits involve drinking a lot of water to flush the metabolites out of your body and then using creatinine or vitamin B12 to mask the dilution. There’s little research on whether these kits are safe or effective. When testing for drugs, someone may take a 1.5-inch hair segment to test for drug use during the past 3 months. But if there’s a chance you’ll receive testing for cannabis, it’s best to prepare for the possibility that the urine test will be accurate for longer. With those methods in mind, the truth of the matter is the only method for ensuring that you’ll pass a drug test is abstaining from marijuana use. If you stop using marijuana in preparation for an upcoming THC drug test with enough time to spare, you may be able to flush the THC out of your system.

This type of testing is more expensive and time-consuming than qualitative tests and is normally reserved for people who have tested positive in a qualitative test. It needs to be done in a laboratory and is used when a more defined value is needed, say, for prosecution.
Marijuana Showing Up on Drug Tests
The difference is it’s in pill form and you will be ordered to drink several bottles of water in order to carry out a dilution regiment. It is used to help in thoroughly flushing the system rather than just to produce dilute urine. Detoxing the blood may be difficult to do safely, but it needs a dilution regimen. You will be asked to drink several ounces of water and given a drink containing b-vitamins, diuretics, creatine, and electrolytes.
- Although conventional wisdom says at least 30 days, the answer is not straightforward.
- Hair follicle tests are best for showing long-term patterns of use.
- If you smoked just one joint one time, it may be out of your system as soon as 24 hours.
Cannabis use cannot be detected in a standard blood test your doctor would use. It requires a specific blood test that can be on the costlier side. Plus, a doctor would require your consent to administer a THC test. Genetics can even affect your test as some people can have subtle variants in certain enzymes that eliminate THC that can shrink these detection windows. In addition to how you consume cannabis there are certain biological factors that can also influence how long cannabis remains in your body.
Saliva
Every time you consume it, weed stays in the system for a specified period, whether you’re a chronic user or you’ve just smoked it once. Knowing how long THC metabolites remain present in your body can be helpful, especially if you’re going to have an upcoming drug test. Weed tends to be very detectable and remains so far longer than most drugs. In this article, we’ll have an in-depth look at how cannabis drug residues remain in the urine, saliva, hair, and blood, as these are the four primary samples taken for drug testing.
As your body processes some of this old fat it can release THC into your body. This may not be enough to make you feel high but it can mean there are enough trace amounts of cannabinoids to show up in a urine test. What separates cannabis from hemp, from a legal standpoint, is that any plant from the cannabis family that has less than .3% THC is considered hemp and legal.
When marijuana is smoked, vaped, or dabbed, these short-term effects manifest within seconds and become fully apparent within just a few minutes. Depending on your metabolism and the potency of the product consumed, these effects typically last for one to three hours. The euphoric effects of THC can fade rather quickly, as these effects usually last for just a few hours when inhaled. However, THC and its metabolites can stay in your system for weeks after consumption, and in some cases, even longer. This puts marijuana users constantly at risk of failing a drug test. Drinking more water can help the body eliminate traces of marijuana quicker than usual.
- Taking tolerance breaks can help decrease the amount of THC and other cannabinoids and metabolites in your system which can help shrink some of these detection windows.
- Some drug metabolites were eliminated by each shampoo and deionized water.
- THC metabolites can be detected in saliva for one to three days after occasional consumption or a month if you consume regularly.
- Marijuana preparations are usually smoked in pipes, joints, or water pipes (bongs).
How long tests can detect weed is dependent upon how long it takes for your THC to metabolize, says Medical News Today. Once the THC metabolites are stored in your hair, they will stay there until you cut your hair. 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. So the amount of THC that a person consumes is a significant factor.
How Long Does Weed Stay In Your Body?
Hair tests can detect THC metabolites for as long as 90 days and increase with frequency of consumption. THC metabolites can be detected in saliva for one to three days after occasional consumption or a month if you consume regularly. How long weed — or the presence of THC metabolites — is detectable depends on the type of drug test administered. It’s also affected by your unique physical functions and frequency of consumption.
- THC itself is only detectable in the bloodstream for a short period of time after use.
- Employers have to pay a lab to provide drug test results, so they’ll generally only make the investment in a drug test if they’re planning on hiring a prospective employee.
- Mega Clean and other detox drinks by Detoxify are solid detox drinks at reasonable prices.
- Plus, frequent cannabis use means there’s simply more THC and metabolites in your system to be found by these tests.
- Recent studies have also investigated the duration of THC in the body.
