Read on to find out the detection windows for cannabis in urine, blood, saliva, hair, and more. How long is it detectable via drug testing? How long does it take to break down metabolize? What factors affect how long it stays in your system? Is there anything you can do to metabolize it faster? How long does it take to feel the effects? This THC detox kit could help you check to see if your body has retained any residual metabolites of weed long after you have smoked or consumed it.
Like most other kits, this, too, looks for traces of THC in your urine samples. Note: The package needs to be unsealed at room temperature and used immediately.
In other words, open it only when you have the urge to urinate so that you can use it. Dip the test panel in the urine sample for 10—15 minutes as indicated by the arrow. Do not let the urine sample go above the arrow. Remove the test strip and leave it for 10 minutes on a non-absorbent surface, such as a paper plate or plastic dish. Two lines: This represents a negative test result.
In this case, one colored line is on the control region, and another colored or faded line is over the test region. One line: This represents a positive test result. There will be one line over the control region and no lines over the test region. The THC levels in your body in this case are high enough to be detected and you are likely to fail the test. No line: This implies a faulty procedure.
You might have made an error in the procedure and need to redo the test with a new kit. Note: Once opened and used, these kits cannot be reused. Kits that are left exposed for just 3 — 4 minutes are useless and might be the reason no lines appeared. In the human body, cannabinoids break down into numerous specific metabolites that are then flushed out through urine, stool, saliva, phlegm, fallen hair, and sweat. As you might notice, there are multiple ways to detect the presence of these metabolites in the body.
Some tests are quick, while some are more accurate, and some are good at detecting recent substance consumption, while others detect it over a longer duration. This is the most common method of testing consumers for drugs. It can detect the presence of drugs in the human body for about a week or so for a new user and up to 30—45 days for habitual consumers. It is easy on the wallet but takes a longer time to be conducted. Blood tests are not randomly conducted.
These apply only to specialized or sanctioned drug tests. A blood test is a long and meticulous test and requires more sophisticated equipment. It can detect weed in your system for up to 45—60 days if you are a regular weed user.
The testing of saliva to detect the presence of drugs is the least commonly used method. A saliva test is performed rapidly and is a part of the federal government or roadside law enforcement drug test. It serves as an easy alternative to urine tests. Saliva retains THC traces for about 1—7 days in some cases. A person getting drug tested with the hair follicle method faces a real challenge.
It is the fastest-growing and most technologically advanced method of detecting drugs. The hair follicle test is gaining rapid popularity among the government and other organizations because of its ability to detect drugs consumed about 90— days ago. There are several individual factors that determine how long THC more specifically Delta-9 remains in your body. These factors may include:.
Age, gender, and frequency of exposure also determine the duration for which THC may linger in your body. It is relatively easier and faster for a person with lower body fat to flush out the toxins. These residues are safely stored in your fat cells and are detectable in samples of your urine, blood, hair follicles, and saliva. This is why drug tests are designed to test such samples. The easiest way to prepare your body for a urine test is by flushing out the toxins.
The urine test is conducted in two steps. The first one is an immunoassay test, which may show false positives, too. Hair follicle tests employ two steps. The first inch and half of a strand of hair are screened for the test. This test works slower than the urine test and might also end up showing false positives. A blood test for weed can be highly effective, as long the authorities have the right equipment for it. Your blood starts storing traces of THC right after smoking weed.
Q: What is the best way to detox before a drug test? A: There is no single foolproof trick that will ensure the best results every time.
You need to develop a mixed approach to the various detox methods available and find the best fit for you. Physical exercise is a must. Drinking gallons of water, hitting the gym, and burning those extra calories should help flush out the toxins and leave you more cleansed than before. While a high might only last a few hours, cannabis can linger in your body for days after you consume it, experts say.
But exactly how cannabis works its way through your system is a complicated question. Studies that he is working on and hopes to publish soon find that people reach a peak level of intoxication within about five minutes of smoking cannabis.
A number of things could affect how intoxicated you get after smoking cannabis, said M-J Milloy, the Canopy Growth professor of cannabis science at the University of British Columbia, and research scientist at the B. Centre on Substance Use. While smoking or vaping cannabis has a very quick effect, he said, it takes longer to feel an effect if you eat it — up to two hours after consuming.
Exactly how long it remains, though, is still a matter of debate. An article on urine drug screening by the Mayo Clinic suggests that cannabis can be detected in urine for between three and 30 days. Drug tests can detect tetrahydrocannabinol, or THC, in urine, blood, and hair for many days after use, while saliva tests can only detect THC for a few hours. This is because of the way the body metabolizes THC. THC is a lipid-soluble chemical.
This means that it binds to fat in the body , which increases the length of time it takes for someone to eliminate THC completely. Research on the amount of time a test can detect marijuana shows a wide range of averages. Research from estimates a detection window for a single marijuana cigarette of about 3 days. Detection windows also depend on the kind of test a person undertakes. General estimates for various marijuana tests are as follows:.
Drug tests can detect relatively small quantities of THC, and the amount of THC in a given marijuana cigarette varies. However, little research has examined exactly how much a person must smoke to fail a drug test. Studies consistently find that frequent weed users are more likely to fail drug tests than infrequent users.
A study in the journal Clinical Chemistry examines marijuana users smoking a single cigarette with 6. Urine concentrations of THC were highest 0. Using a highly sensitive urine test, researchers detected THC in the urine of percent of frequent users and 60— percent of infrequent users. A study reports on testing where hair samples from marijuana users reporting heavy, light, or no use of marijuana. For the study, researchers cut hair into 1-centimeter sections to test for exposure of up to a month prior.
Some 77 percent of heavy users and 39 percent of light users produced positive tests. No non-users had positive test results, suggesting that false positives in hair tests are relatively rare. More sensitive tests can detect lower doses of marijuana.
