How Long Does Marijuana Stay In Your System? Urine, Blood, & Hair
Testing urine is one of the most common methods for determining marijuana use. Most urine tests can detect marijuana several days after you have last had it. However, if you are a heavy marijuana user, marijuana may still show up in your urine even after several weeks. The non-THC components of marijuana itself do not stay in the body long periods of time, which is why hemp and other marijuana-based products will not cause you to fail a drug test for marijuana. However, most drug tests are designed to detect THC specifically. 80%-90% of the total dose of THC is usually excreted within the first week, however, the remaining 10%-20% can linger for much longer.
How long does it take for the effects of cannabis to wear off?
It should not be used in place of the advice of your physician or other qualified fun group activities for substance abuse treatment healthcare providers. The truth is that it doesn’t really matter how you consume cannabis, whther it be edibles, oils or smoking it will generally result in the same level of THC-COOH. With edibles, there is more conversion of THC to THCCOOH, which is what urine tests look for. Since metabolism of edibles is slower, the amount of time it takes to reach peak THC in blood is delayed. As a result, edibles can be a bit stronger, both in their effects and in THC content, but for the most part they will only extend the time that THC-COOH stays in your system by a day or so. 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.
After weed enters your system, it can take between one to three hours to feel the complete effects and another one to three hours for those effects to wear off, according to Healthline. The effects of edibles last much longer than smoking, according to the American Addiction Centers. One of the most effective ways to detox hair is using a technique called the Macujo Method. The main purpose of this method is to clear the metabolites from hair. The process requires opening up the hair cuticles to expose the middle part of the hair follicle where metabolites are stored.
Health Challenges
- If you’re a cannabis user, it’s important to know how to properly detox from THC in case of a drug test.
- THC, CBD, and their metabolic byproducts, called metabolites, are lipid-soluble and accumulate in fat reserves throughout the body.
- Marijuana is only detectable in oral fluids for about 24 hours.
- The strength and quantity of the THC consumed can be the difference between a positive and negative test, as drug tests are searching for THC, not cannabis.
- Once 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.
A series of quantitative tests can determine if drug usage is ongoing or has stopped. When it comes to testing for marijuana use, blood tests are not often used. This is because blood tests have a narrow window of time to detect marijuana use. These tests typically only work within three to four hours when a person uses marijuana, which is when THC is still in the bloodstream. 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. However, blood tests can detect THC metabolites for a few days to a few weeks, depending on how much you consume.
How Long Does Marijuana (Weed) Stay in Your System?
However, it may take 1–3 hours does alcohol cause gallstones for effects to peak when cannabis is ingested. These kits don’t work reliably, and drinking large quantities of water in a short period of time can be fatal. 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.
Someone who eats well, exercises and gets enough sleep has a body that will function better, meaning it will get rid of THC at a faster rate than someone who is in poor overall health. However, doing a lot of exercises right before a marijuana test can increase the concentration of THC. This is because THC is stored in fat, and if you exercise and that fat breaks down, THC is released back into your system.
THC can be present in urine for anywhere between a couple days to 30 days, and it depends on a variety of factors. Delta-9 THC undergoes metabolism in the liver to another psychoactive compound, 11-OH-THC, and then further metabolism to the inactive THCCOOH. Other drugs, like rifampin, may decrease the amount of THC in your body. THC can also decrease the effect of theophylline sheila shilati and chlorpromazine. There is no way to know exactly how long THC will stay in someone’s system for a drug test.
This can actually backfire because your urine can get so diluted that the sample comes back as unusable. In the worst case scenario, this will also cause the administrator to flag your test and force you do a supervised one next time. In the best case scenario, they’ll just ask you to come back and this will give you more time to get the THC out of your urine.
In fact, if you do this, you might increase your chances of testing positive. The most common cutoff for urine tests is 50 nanograms of THC-COOH per milliliter (ng/mL). Each of these cutoff points, of course, results in a widely different window of detection. THC, CBD, and the rest of the cannabinoids have metabolic byproducts, called metabolites. These substances are lipid-soluble, meaning they accumulate in fat deposits throughout the body.
