The main cannabinoid of cannabis, THC lasts in your body for a max of thirty days. It will be detectable in hair for up to the 90-day limit measuring 1.5 inches of hair.

How is marijuana processed?
Inside of you, tetrahydrocannabinol will be processed by the liver and rendered as 11-OH-THC. 11-OH-THC is the drug that will activate the receptors in your nervous system. Further processing will see it turned into THC-COOH and 11-nor-9-carboxy-TH. These are the forms that will bind to fat and stay in your body for up to three months being released only as you burn fat. The leaching of these forms into the blood will keep a steady level in the urine and saliva.
How long weed stays in the system
Frequency of smoking
Maybe you had one smoking session or two joints, that could be clear of your system in one day. On the other hand, if you took strong edibles or dabs every day that could take as long as 3 months of abstinence to be free of your system.
ROA aka Route of Administration and its effect
Eating your cannabis will give a slower but more concentrated hit of THC. Eating may spike blood and urine levels later but more intensely than smoking. Smoking powerful concentrates like dabs will cause a quick spike of THC, but it will likely leave the body quicker.
Content of Body Fat
THC binds to your fat cells. So, if you’re a heavier person, you may have a lot of stored THC. If you suddenly start burning fat, the THC will come flooding out of these cells. This is why you should avoid detox products that contain fat burners like caffeine for detoxing within two days of your test. They should only be used to lower the total THC content of the body at least a week before your test. If you are still burning fat during your test, you will have elevated levels of THC in your blood, saliva, and urine. This is what you are trying to avoid. Before your test does not do any dieting and especially not low carb since it is exceptional at burning fat. This should be done only weeks in advance to detox marijuana through fat burning, sweating, stool, and urination.
Drug test types
How long does it take the pot to leave the system for a urine drug test?
THC stays in urine for 30 days max. Weed gets out of your pee in a manner that lags behind that of its presence in saliva, it is the same as the rate at which it leaves the blood. When ingested, levels of THC and its metabolites are high in the blood and urine. Later, it may be stored in the fat cells and hair and only a low level will be detectable in the blood and urine as the fat cells burn at a constant slow rate and release the stored THC into the blood, which is then sorted by the kidneys into the urine. Cannabis is detectable inside your pee for the period that the fat cells are leaking a constant rate into the bloodstream. How long it will take the major metabolite THCCOOH to leave the system entirely depends on how much you consumed and how frequently as per the above chart.
- The best way to clean your system for a urine drug test has always been via a process of dilution. Dilution does not really rid your body of THC faster, the only thing that can do that is a fat-burning, but that will also cause a flood of THC into your blood and urine. Rather, most detox drinks and methods work by diluting the urine with plain old H20 then adding back the vitamins and creatinine the testers will be looking for to make sure the urine has not been diluted. When doing dilution, you need water, creatine, b-vitamins, and salt, lite salt, or baking soda as your electrolyte. You can buy a detox drink to take 2 hours before your test and it must include each of those ingredients in order to be effective.
Has It Been Scientifically Proven that a urine test can be beaten?
Yes. One study published in the Journal of Addiction medicine says this: “This study supports the theory that urine dilution is not a random happening and it may adversely affect the integrity of the drug-testing process.”
The researchers uncovered that some samples were diluted yet had sufficient creatinine, yellow color, and specific gravity values to pass as valid, even if drugs were present below threshold levels. They verified that the test had been beaten via dilution.
How long is marijuana detectable in your hair follicles?
90 days is the window of detection. Your hair grows at a rate of one-half inch per month. Therefore, 3 times that is 3 months and 1.5 inches of hair. It has the history of your drug usage for that long. Now, drug residues may still be present in the hair past that window and even into two years if you have really long hair. But legally and by standards of practice, only the 1.5 inches closest to the scalp is tested. It is often called a hair follicle drug test. However, the hair follicle from which the hairsprings inside the scalp is not excised and tested. It’s the hair shaft above the follicle that is tested. The hair shaft holds the drug residues of 90 days of usage, inside of the hair cuticle.
Methods of Testing and Analysis
This is how the actual test works, a sample of hair will be taken from your head. 1.5 inches, 90 days of drug use history. First, an EILSA test is done. This test uses antibodies that will attach to the drug if present and reveal the presence of the drug and the level of the drug in some cases. If this test is positive, the result may be confirmed with the gas chromatography-mass spectrometry (GC-MS) test. The second test will rule out a false positive.
The hair shaft drug test is surely the hardest one to beat. Once the drugs are there in your hair cuticle, it stays there, for years if you don’t cut your hair. But the detection window is only 90 days. However, you can beat a hair drug test and this has been scientifically proven. The journal Drug Test Analysis published a study where they compared 4 detox shampoos that claim they will get enough drug metabolites out of your hair that you will pass a drug test. They gathered hair samples that were positive for several drugs. They agitate the hair in the shampoos for several hours. Each shampoo and even deionized water removed some drug residues from the hair samples. So, shampooing your hair with anything whatsoever before the hair drug test will remove some drug residues if you get down into the 1.5 inches of hair coming from the scalp.
A hair shaft drug test is the hardest to beat. Beating a hair follicle test is especially difficult because it measures the level of drugs taken in the 90 days previous to the day of testing. A study published in 2019 in the journal called Drug Test Analysis found that a hair test for alcohol was possible to beat with at least one of the four detox shampoos tested. Each shampoo and deionized water removed some drug metabolites from the hair but was not sufficient to cause a false negative. Yet, one shampoo was a clear winner. High Voltage Detox Folli-Cleanse Shampoo showed: “The fourth shampoo showed additional heavy washout effects with a decrease of up to 86% after 2.5 hours.” That’s enough to get you that false positive that you need to pass your drug test, scientifically proven.
Another study was published in the International Journal of Legal Medicine. This one tested Ultra Clean, our second scientifically proven detox shampoo. They found “…a slight decrease in drug concentrations could mostly be observed e.g. cocaine (n = 10) -5%, 6-MAM (n = 12) -9%, morphine (n = 12) -26%, THC (n = 4) -36%.” This is a reduction of 30 % or less from about one washing of the hair with Ultra Clean. This is good, but not enough to beat a drug test. You need to use Macujo or Jerry G Methods to pass a hair drug test.
Your Saliva
Your Saliva drug test detection times only cover a window of 3 days. It is the easiest test to beat, just stop using it for 3 days. The majority of drugs won’t be detectable around the salivary glands in just one day. Use a peroxide mouthwash before the test.
How long is marijuana in the bloodstream?
Weed stays in your blood by spiking in about six hours, then low levels may be detectable from days to months as it leaks from fat cells at a slow rate. During this time, it will be detectable in the saliva, sweat, and urine. Search our site for how to beat drug tests and keep your health information private.
Conclusion
Weed stays in your blood and hair longer than any other drug, this is because it hides out in fat cells and leaks a little into the bloodstream every day. It usually has a positive anti-inflammatory effect on the body. The only way to be sure your THC metabolite levels are below the detection window is to buy a test kit from your local pharmacy before you have a drug test. If you are positive, search our site to learn how to do a proper dilution regimen. Or, just get a product like Mega Clean that has all you need to successfully carry out a dilution regimen. Good luck, smoke up, and stay safe! Peace and love upon you, brothers and sisters of the earth.
