How Long Does Weed Stay in Your System, Urine, Blood & Hair?

But, there is one tricky thing when it comes to exercising. In fact, try to avoid all exercise a couple of days before the big day. If it’s already too late and you don’t have the time, there are a few things you can do to speed up the detox process. If you know you’re going to get tested for cannabis, I suggest you reverse engineer the chart above and stay cannabis-free for that time period. THC metabolites can be detected in sweat for about one to four weeks.

Mental Health Resources

• The time it stays detectable varies based on how often someone uses it.
• When you eat an edible, cannabis has to go through the entire digestion process before cannabinoids enter the bloodstream.
• The remaining THC and its metabolites enter the circulation.
• Lemonades and citrus juices are full of electrolytes which are great detoxing agents.
• In fact, the hair drug test was developed to identify long-term users rather than one-time or infrequent users.
• These side effects are generally mild and subside as the delta 8 wears off.

Drug testing might be degrading, unnecessary and ineffective, but until the federal government changes tack on marijuana, it will likely remain a reality, even in legal states. The best thing you can do is use the information you’ve learned here to stay on the right side of the cutoff line, keep your job and not mess up your parole or rehab plans. However, THC-COOH in saliva isn’t part of the federal testing guidelines, and it’s only recommended (Cone and Huestis, 2007) to substantiate use, not prove it. This is essentially because THC is metabolized inside the body after ingestion, rather than in the mouth itself. So while small quantities of THC-COOH will drug addiction likely be present, this isn’t the main thing that saliva testing is looking for.

Addiction Treatment

• THC triggers your brain to release large amounts of dopamine, a naturally occurring “feel good” chemical.
• Cannabis may aggravate existing respiratory illnesses, such as asthma and cystic fibrosis.
• Knowing what you can and can’t do legally will help you pass a drug test successfully.
• Higher doses and more frequent use usually increase the time it takes for weed to leave your system.
• THC metabolites stay in the body for at least 1–30 days after use.

But they’re excellent for revealing whether you consumed marijuana — in any form — at some point in the past. For employers who have a zero tolerance policy, this is enough to move on to another candidate or fire you if you’re currently working. Because of this, edibles can put you at a longer risk compared to vaping or smoking cannabis based on how long does weed last in your system your use habits. When you smoke or vape medical cannabis, the short-term effects come on within seconds and peak within a few minutes. Depending on the potency of the herb and your metabolism, the effects can last anywhere from one to three hours. But in terms of common testing procedures, hair follicle tests are typically looking for cannabis use back 90 days.

How does THC concentration affect detection times?

The effects from edibles are also typically enhanced compared to smokable or concentrated marijuana products. On their way through the digestive system, edible marijuana products pass through the liver. In the liver, the effects of marijuana concentrate, so when they reach the brain, the effect is stronger. Properly dosing with edible products is challenging because of the time lapse and the concentration effect. THC affects your brain while you’re consuming marijuana and for up to a few hours afterward. Through continual dosing, you could theoretically maintain the effects indefinitely.

Blood tests

Even after a blood test cannot detect THC, traces can still show up in a hair test. Hair tests are not often used because they’re lengthier and more expensive. However, they’re very accurate and can show a pattern of marijuana usage for months after the last dose. Traces of THC are deposited on the hair shafts from the blood vessels in your scalp and remain there as the hair grows out.

This article will cover how long THC can traditionally stay in your system, what gets tested, and will help you better understand how your body metabolizes THC. Unfortunately, much of the information available online about this topic is misleading at best. It is very common for sources to claim that THC’s metabolites will be detectable in your pee for over 30 days, and even academic sources (Moeller et. al., 2017) make this claim. Researchers believe around 15 to 20 percent of a THC dose is eliminated when the user urinates.

Examining Weed’s Half-life in Blood Samples

These products, while legal, could trigger a positive result as they can create the same byproducts or leave trace amounts of THC in your bloodstream. This can get complicated because there are legal versions of THC like delta-8, delta-10 and Dronabinol a.k.a. Marinol. The ramifications of a positive drug test can negatively impact your life by putting your health insurance, livelihood or career at risk. THC is detectable for around 90 days in your hair, but in a surprising number of cases, it’s not detectable at all.

What role does the liver play in processing marijuana?

Once a certain test is chosen, the experimenter needs to select its cutoff concentration of THCCOOH above which it’s considered a positive test. For most urine tests, the most common cutoff is 50 nanograms per milliliter (ng/mL) but can be as low as 15 ng/mL — with each resulting in largely different detection windows. Once https://ecosoberhouse.com/ a specific test is selected, the experimenter must then choose its sensitivity, or the cutoff concentration of THC-COOH above which a test is considered positive.

• We publish material that is researched, cited, edited and reviewed by licensed medical professionals.
• An older study notes a slight increase in THC levels following exercise in people who regularly use cannabis.
• We can give an estimate of the amount of time marijuana remains in the body, but the most reliable way is to test yourself twice weekly until your first, morning urine sample tests clean.
• Modern marijuana drug tests are set up to detect any traces of THC, so yes, delta 8 will appear on a drug test, causing a positive result.

Marijuana detection windows depend on how much you smoke or ingest and how often. Generally, higher doses and more frequent use are linked with longer detection times. Additionally, heavy users can take longer to report a negative result because of the way our hair grows. So even if you’ve abstained for a long period of time there may still be trace byproducts in your hair. It’s also important to know that 15% of drug tests results from hair follicle tests can be inaccurate. Hair color or different treatments can strip some of the content of hair leading to inconclusive or false negative results.
