The effects of marijuana fade quickly, but the drug can be detected in the body for weeks and sometimes longer. The amount of time the active ingredients and breakdown products of weed remain in the system can range from a few hours to 90 days, depending on how often or how much marijuana the person has been using.
For example, a single dose of weed may be detected in your system for up to 13 days, depending on the type of test used. If you rarely smoke weed or only have a few puffs, it will leave your system more quickly than if you use marijuana frequently or heavily.
Although a number of states in the U.S. have active medical marijuana laws and recreational use of marijuana for adults over the age of 21 is legal in 12 states, Washington, DC, the Northern Mariana Islands, and Guam, the federal government continues to classify marijuana as a Schedule I controlled substance.
The FDA has not yet approved medical marijuana for any medical indication, but it is often prescribed for chronic pain, nausea, HIV, multiple sclerosis, glaucoma, and irritable bowel syndrome (IBS).

How Long Does It Take to Feel the Effects?
The effects of marijuana can vary from person to person. Some people may feel euphoric and relaxed while others feel anxious and paranoid. In other cases, people report feeling “dopey” and experience a loss of interest in activities or an inability to grasp concepts.
The chemical in marijuana that makes you feel “high” is tetrahydrocannabinol, also called delta-9-THC or simply THC. It enters the body’s bloodstream rapidly after smoking marijuana.
If weed is ingested orally rather than smoked, it takes longer to be absorbed into the blood, usually from 20 minutes to an hour and a half, but this can vary based on the amount taken as well as physiological factors such as absorption and rates of metabolism and excretion can influence drug concentrations in circulation.
Effects can be far-ranging depending on the strain, method of consumption, and amount and can include the following:
- Dry mouth
- Swollen eyelids
- Bloodshot eyes
- Pleasurable body sensations
- Increased appetite (“the munchies”)
- Distorted perception (sights, sounds, time, touch)
- Loss of coordination
- Trouble with thinking, memory, and problem-solving
- Increased heart rate
The short-term effects of marijuana on memory, learning, problem-solving, and coordination last for one to two hours, with some lingering effects for up to 24 hours. It’s been shown to impair your driving performance for up to three hours, according to the National Highway Safety Administration.
The effects of weed are also influenced by the terpene profiles of a given strain. For instance, citrus terpene profiles tend to be more stimulating, which may be the desired effect, or may contribute to someone feeling anxious.
It is important to know that not all marijuana is created equal. Unlike other prescription drugs, marijuana products aren’t standardized and can vary considerably in quality, makeup, and dosage.
This variance may contribute to how quickly you feel the effects and what those effects are. THC can interact with alcohol, blood thinners, and anti-anxiety medications, so it’s important to discuss your marijuana use with your doctor.
How Long Does Marijuana Last?
The half-life of marijuana is how long it takes for half of the drug to be metabolized and eliminated from the bloodstream. While there are many different cannabinoids, THC is the one most drug tests are looking for.
THC is rapidly broken down and modified into molecules known as metabolites. At least 80 different metabolites are formed from THC and may have their own effects on the body’s endocannabinoid system. These metabolites are stored in body fat and are gradually eliminated from the body through feces and urine.
Some THC metabolites have an elimination half-life of 20 hours whereas others are stored in body fat and have an elimination half-life of 10 to 13 days.
It takes five to six half-lives for a substance to be almost entirely eliminated. This is why you see advice that one-time use is probably not detectable after five to eight days.
Blood and Saliva
Because marijuana stays in the bloodstream for only a short time, blood tests for marijuana are usually not used. The exceptions are in the case of automobile accidents and some roadside sobriety checkpoints.
Blood or saliva tests can show current intoxication. However, unlike blood alcohol concentration tests, they do not indicate a level of intoxication or impairment.
Daily or near-daily cannabis consumption is likely, but not always, detectable by a hair test up to three months later. But, the hair test is not reliably able to detect infrequent cannabis use or determine the amount of cannabis used.
Urine tests for marijuana metabolites also only show recent marijuana use, not current intoxication or impairment. This is because of the time required between use and your body breaking down THC to the metabolites that are eliminated in the urine. Because many employers have a zero-tolerance for drug use, most workplaces use urine tests to detect recent use of drugs.
False Positive Testing
Workplace testing for marijuana might entail first screening the sample with an immunoassay test, known as the EMIT or RIA. If positive results are returned, the sample is again screened with a gas chromatograph-mass spectrometer (GCMS), which is much more accurate and so false positives are rare.
No known substances would cause a marijuana urine test to return a false positive.
At one time, ibuprofen (sold over-the-counter as Advil, Motrin, and Nuprin) would cause false marijuana positives. But today’s tests have been adjusted to eliminate that problem.
In places where marijuana is legal, roadside blood tests have been known to show some false positives in people who had been legally consuming cannabis but were not actively intoxicated at the time of the test. A 2016 report detailed a Belgian policy of testing oral fluid at the roadside that found it decreased these types of false positives.
Factors That Affect Detection Time
The length of time marijuana remains in your body depends on many different factors, including frequency of use, body mass, metabolism, sex, and hydration levels.
Frequency of Use
There is some evidence that the length of time that marijuana remains in the body is affected by how often the person uses marijuana, how much they use, and how long they have been using.
People who use marijuana regularly have reported positive drug test results after 45 days since last use, and people who use more heavily have reported positive tests up to 90 days after quitting.
In a 2017 study of 136 people who use cannabis subjected to hair tests, the presence of five cannabinoids, THC, THC-OH, THC-COOH, cannabinol, and cannabidiol, were present in 77% of the heavy users and 39% of the light users.
Women often metabolize THC at a slightly slower rate since they tend to have higher levels of body fat than male counterparts.
The faster your metabolism, which can be impacted by age, physical activity, and certain health conditions, the faster marijuana will exit your body.
Body Mass Index (BMI)
THC metabolites are often stored in the fat cells in your body, so the higher your body fat (or BMI), the slower you’ll likely be able to metabolize and excrete marijuana.
Body Mass Index (BMI) is a dated, biased measure that doesn’t account for several factors, such as body composition, ethnicity, race, gender, and age. Despite being a flawed measure, BMI is widely used today in the medical community because it is an inexpensive and quick method for analyzing potential health status and outcomes.
When you’re dehydrated, you’ll have more concentrations of THC in the body. Flooding yourself with water won’t make you pass a drug test, however. Instead, it will dilute it and you’ll likely need to retake the test.
Smoking vs. Vaping vs. Edibles
The method of use also impacts the detection time. If marijuana is smoked or vaped, the THC levels in the body will drop faster than if you ingest it. Edibles take longer to break down in the body and leave your system.
How to Get Marijuana Out of Your System
Many employers have a workplace drug policy that includes random drug testing for current employees and routine testing for all new job applicants.
If you are required to take a urine test on short notice for employment or other purposes and you have recently smoked marijuana, you are probably going to fail the test. This is particularly true if your use is regular or heavy.
You can be fired for failing a drug test even in states where the recreational use of marijuana has been legalized.
The only completely reliable way of passing the test is to stop smoking or ingesting marijuana or cannabis products.
Although you will see many tips on how to beat a marijuana drug test, most have proven to be urban legends. Some of these questionable techniques include the following.
Washing Your System Out
This method entails drinking a lot of water or liquids and urinating several times before the test, then taking vitamin B-12 to add color back to the urine. Although this may lower the percentage of THC found in the urine by diluting it, it will not totally eliminate THC metabolites.
Some people will also try to exercise before the test, but that can actually backfire, depending on the test, as it can release stored THC from fat into the blood, according to one study in the journal Drug and Alcohol Dependence.
Using Drug Screening Agents
Some companies sell various substances and herbal teas that are allegedly capable of “cleaning” the body’s system of traces of marijuana. There is little evidence that any of them actually work. The catch is that most of them have to be used over an extended period of time, during which the body will naturally eliminate THC anyway.
Tampering With the Test
This involves adding something to the urine to contaminate the sample. There are tales of using Visine, bleach, salt, or detergent to the urine sample, but these items are easily detected by the lab.
Several commercial products are sold as urine test adulterants, but none are 100% foolproof. All of them can be detected by the laboratory if a separate test is run for them.
Symptoms of Overdose
It is very difficult to physically overdose on marijuana because the lethal dose is so much higher than the effective dose. Very few marijuana overdoses have ever been reported. If someone you know has taken too much marijuana, and that is the only thing they have taken, an overdose is highly unlikely, but that doesn’t mean that marijuana is not harmful.
Psychological distress is possible as is impairment of judgment, both of which can lead to hazardous behaviors that can harm yourself and someone else. Although rare, people can experience THC toxicity when using marijuana in high doses, especially in the form of edibles. Symptoms can include:
- Heart arrhythmias
- Psychosis or paranoia (or exacerbation of pre-existing mental health conditions)
- Uncontrollable vomiting
If you or someone you love has a family history of mental illness, it is beneficial for you to consult your doctor before using marijuana.
The concept of “set and setting” is also important. Since people who have taken too much marijuana can experience sensory overload, minimizing overstimulating inputs in the environment can help them to relax. Some people are also more affected by marijuana than others.
You may have a prescription for medical marijuana, or you may want to partake of weed or marijuana edibles in states where it is now legal for recreational use at the state level. There is a common perception that you cannot develop a physical dependence on marijuana, but this is not the case. Psychological dependence is also a consideration.
If you discontinue marijuana after regular or heavy use, you may experience symptoms of withdrawal. Signs of marijuana withdrawal include:
- Appetite change
- Cramps or nausea after eating
- Digestion problems
- Mood swings
- Sleep disruption
- Weight gain
- Weight loss
If you find that you can’t handle symptoms of withdrawal without relapsing, you may be at risk for a substance use disorder. Do not be afraid to seek out professional support from a mental health professional.
There are therapists who can help you understand your reasons for using. They also can help you determine how cannabis use is impacting your life, and how to develop a plan to stop using if that ends up being the best choice for you.
How long does one smoke session stay in your system?
It showed: For someone smoking cannabis for the first time, tests may detect it for about 3 days. In someone who smokes cannabis three or four times per week, the detection window is 5?7 days. For people who smoke cannabis once a day or more, tests may detect it in their system for 30 days or longer.
Do edibles show up in drug tests?
Do Edibles Show Up in Drug Tests? Yes, edibles do show up on drug tests along with other THC-containing products. Additionally, because THC is processed differently when it’s ingested, it may actually last longer in the body than weed that’s been smoked
How long do you need to be clean to pass a urine drug test?
Aside from launching a legal challenge, your best defense against urine testing is to be clean. Unfortunately, this may be difficult since urine tests may detect marijuana 1-5 days after an occasional use, 1-3 weeks in regular users, and 4-6 weeks in multiple daily users
What happens if you add water to your urine test?
If a tester drinks large amounts of water (at least one gallon) before taking a drug test, urine becomes diluted and metabolites from drugs may become undetectable. This may cause the first round of results to be inconclusive.
What is a good excuse for failing a drug test?
Furthermore, employees may have excuses for failing a drug test: they ate too many poppy-seed bagels, accidently picked up the wrong brownie at a party or were stuck in a car with someone who was smoking weed. Perhaps they’ll argue that the test is wrong. Employers need to consider how they’ll handle these situations.
How do you fail a urine drug test?
Today’s drug tests can detect even trace amounts of alcohol, and for longer after exposure. So if you use anything with ethyl alcohol, your breath, blood, or urine sample might get flagged for possible signs of drinking. The same thing could happen even with alcohol-based hand sanitizers if you use them regularly.
How long before a urine test should I drink water?
The only thing that affects a dilute sample is the amount of fluid taken in within a short period of time prior to providing the urine sample. If you are seeing results that show you are getting close to a dilute sample, try to stop drinking any fluids 2-4 hours prior to providing the sample.
How far back does a urine test go?
Drug testing specimen types
Illicit substances are detectable for only five to 10 days in urine; whereas, hair drug tests can detect drug or alcohol use for up to 90 days. Blood testing is very accurate, but costly and invasive. It does have a shorter detection period (minutes to hours), however.
Can you still get hired if you fail a drug test?
Can You Still Get Hired If You Fail a Drug Test? For the most part, no. If the test result is proven to be legitimate (especially after multiple retests), you will most likely lose your job. If drug testing was part of a screening application, the company will probably revoke your job offer.
How many days can drug test detect?
Opioids like heroin and oxycodone are detectable for between 1 and 3 days after last use. Stimulants including cocaine, meth, and ADHD medications are detectable for about 2 or 3 days. Benzodiazepines and MDMA generally flag a urine test for up to 4 days after last dose.
What shows up in a drug urine test?
Urine drug testing may screen for multiple substances, including amphetamines, methamphetamines, benzodiazepines, barbiturates, marijuana, cocaine, opiates, PCP, methadone, nicotine, and alcohol.
Should I tell my employer I can’t pass a drug test?
1 attorney answer
You should absolutely tell your employer that THC may appear on the drug screening.
How Long Does Weed (Marijuana) Stay in Your System?
How Long Does Weed (Marijuana) Stay in Your System?It varies according to dose and frequency of use. Weed, also known as cannabis, is usually detectable in bodily fluids for 1 to 30 days after last use. As with other drugs, it may be detectable in hair for several months, particularly in people who use cannabis on a daily or near-daily basis.The cannabis detection windows depend on how much you smoke or ingest, as well as how often. In general, higher doses and more frequent use are associated with longer detection times.In daily use, cannabis may be detectable for several months after last use. Read on to find out the detection windows for cannabis in urine, blood, saliva, hair, and more.One of the most abundant components in cannabis is a chemical substance called THC, which stands for delta-9-tetrahydrocannabinol. Drug tests measure THC and its by-products, or metabolites. These metabolites remain in your system long after weed’s effects have worn off. How long weed is detectable in your body depends on how much you smoke or ingest, as well as what type of drug test is used. Urine testing is the most common drug testing method. While detection windows may vary, a 2017 review suggests that weed may be detectable in urine for the following amounts of time after last use: single use: 3 daysmoderate use (four times per week): 5 to 7 dayschronic use (daily): 10 to 15 dayschronic heavy use (multiple times per day): more than 30 daysCannabis metabolites are fat-soluble, which means they bind to fat molecules in your body. As a result, it can take some time for them to leave your system, particularly if you have more fat molecules in your body. Blood tests typically detect recent cannabis use, or use that has occurred within the last 2 to 12 hours. However, in cases of heavy use, it’s been detected 30 days after last use. Chronic heavy use increases the length of time that it can be detected.Saliva testingSaliva testing has a short window of detection, and in some cases may detect same-day cannabis use. A 2020 review found that THC was still detected in the oral fluid of frequent smokers 72 hours after use. THC may be detected in oral fluid longer than in blood after acute use. Weed can enter the saliva through smoking and exposure to smoke. However, its metabolites are only present in saliva when weed has been smoked or ingested. In jurisdictions where weed is illegal, oral fluid may be used for roadside testing.Hair testingHair follicle tests can assess drug use for up to 90 days. After use, cannabinoids reach the hair follicles via small blood vessels, as well as from sebum and sweat surrounding the hair shaft. Since hair grows approximately 0.5 inches per month, a 1.5-inch hair segment taken close to the scalp can provide a window of weed use for the past 3 months.THC is absorbed by the bloodstream when a person smokes or ingests cannabis. Some THC is temporarily stored in organs and fatty tissues. THC is broken down in the liver. It has more than 100 metabolites, but the most significant ones are 11-OH-THC (11-hydroxy-delta-9-tetrahydrocannabinol) and THCCOOH (11-nor-9-carboxy-delta-9-tetrahydrocannabinol).Drug tests look for these metabolites, which stay in your body longer than THC. Eventually, THC and its metabolites are excreted in urine and stool.How long it takes THC metabolites to be excreted depends on the frequency of cannabis use. More frequent use is associated with a higher…
How Long Does Marijuana (Weed) Stay in Your System?
How Long Does Marijuana (Weed) Stay in Your System?Like many drugs, the duration that marijuana remains in a person’s system varies depending on several factors. Frequency of use, level of tetrahydrocannabinol (THC) in the marijuana, metabolism, and hydration can all impact the results of a drug test.1 Spanish Version Typically, THC, the psychoactive component of marijuana, is detectable for up to 90 days in hair, anywhere between 1 day to a month or longer in urine (depending on how often the individual uses it), up to 24 hours in saliva, and up to 12 hours in blood.2 How Does Your Body Process THC? THC is absorbed into various body tissues and organs (e.g., the brain, heart, and in fat) or metabolized by the liver into 11-hydroxy-THC and carboxy-THC (metabolites). About 65% of cannabis gets excreted through feces and 20% leaves the body through urine.1 The rest is stored in the body. Over time, THC that is stored in body tissues is released back into the bloodstream, where it is eventually metabolized by the liver.1 In chronic marijuana users, THC builds up in fatty tissues faster than it can be eliminated, so THC can also show up on a drug test many days or even weeks after an individual uses it.4 How Long is Marijuana in Your System? THC, a highly fat-soluble compound, has a very long half-life—the amount of time it takes the concentration of THC in the body to decrease by half. How long residual THC levels remain in the body depends on an individual’s marijuana use. For example, one study found that the half-life was 1.3 days for individuals who infrequently used marijuana. More frequent use showed a half-life of somewhere between 5 and 13 days.1 Additionally, detection of THC depends on the sample taken. Windows of detection vary.2 Specimen Detected in System Blood Up to 12 hours Hair Up to 90 days Saliva Up to 24 hours Urine Up to 30 days, depending on the frequency of use Saliva Test The mouth swab provides a quick, non-invasive drug test. A sponge or absorbent pad on the end of a stick rubs along the inside of the cheek or on the tongue. Research indicates that there is significant absorption of THC in the mouth, which increases the concentrations for several hours after use.5 Urine Test THC retains the highest concentration for the longest period of time in urine; thus, urine samples are typically the preferred method of drug testing to detect marijuana use.1 Hair Test Hair testing has a long detection window. Scalp hair can indicate marijuana use for three months.6 However, research indicates that a hair test is most reliable for daily or near-daily users but is not able to detect light cannabis consumption. In fact, one study found that 75% of individuals who self-reported to heavy cannabis use and 39% of individuals who self-reported to light marijuana use tested positive for THC via a hair sample.7 Blood Test Marijuana remains in the bloodstream for a short amount of time, so blood tests for marijuana detection aren’t typically used. That’s because while the THC reaches the bloodstream quickly (within minutes of inhalation), the THC concentrations in the bloodstream rapidly decrease roughly 3-4 hours after ingestion.1 What Factors Impact How Long Weed Stays in Your System? Besides the type of test, other factors that can affect how long marijuana registers on a drug screen include:1,6,8,9 The amount of THC in the marijuana. The route of consumption. THC reaches the organs and bloodstream more quickly when marijuana is inhaled as opposed to ingested. The dosage and frequency of use. An individual’s metabolism rate and excretion routes. The sensitivity and specificity of the test. The individual’s gender, level of hydration, body mass index (BMI), overall health, and genetics. Attempting to Beat a Drug Test Many products have been marketed to help individuals “beat drug tests.” One…

How long does marijuana stay in your system? Blood, urine, and hairWe include products we think are useful for our readers. If you buy through links on this page, we may earn a small commission. Here’s our process.Tetrahydrocannabinol, the chemical in cannabis that makes people feel “high” can stay in the body for several days or even weeks.The length of time this chemical stays in the body or continues to show in a drug test depends on many factors. These include:how much body fat a person hashow often they consume the drughow much someone smokesthe sensitivity of the drug testDrugs such as alcohol may completely disappear from the body in just a few hours. In comparison, weed lingers much longer.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 cannabis shows a wide range of averages. Research from 2017 estimates a detection window for a single cannabis cigarette of about 3 days.The same study emphasizes that detection windows vary and depend on how often a person smokes.It showed:For someone smoking cannabis for the first time, tests may detect it for about 3 days.In someone who smokes cannabis three or four times per week, the detection window is 5–7 days.For people who smoke cannabis once a day or more, tests may detect it in their system for 30 days or longer.Detection windows also depend on the kind of test a person undertakes. General estimates for various cannabis tests are as follows:Urine tests can detect cannabis in the urine for approximately 3–30 days after use.Saliva tests can detect cannabis for approximately 24 hours after use. Some saliva tests have detected cannabis for up to 72 hours.Hair tests are the most sensitive tests, detecting THC for up to 90 days after use. However, these tests are testing the oil in skin that transfers to hair, and so they may occasionally show a false positive. A person who comes into contact with a THC user could, theoretically, test positive on a hair test.Blood tests can only detect THC for 3–4 hours.Drug tests can detect relatively small quantities of THC, and the amount of THC in a given cannabis 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 2012 study in the journal Clinical Chemistry examines cannabis users smoking a single cigarette with 6.8 percent THC.Urine concentrations of THC were highest 0.6 to 7.4 hours after smoking. Using a highly sensitive urine test, researchers detected THC in the urine of 100 percent of frequent users and 60–100 percent of infrequent users.A 2017 study reports on testing where hair samples from 136 cannabis users reporting heavy, light, or no use of cannabis. 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.Numerous factors influence whether a test detects cannabis, including the following:Test sensitivityMore sensitive tests can detect lower doses of cannabis.

How Long Does Marijuana (Weed) Stay in Your System?
How Long Does Marijuana (Weed) Stay in Your System? If you have smoked marijuana, or if you have been exposed to secondhand marijuana smoke, you may be wondering how long marijuana stays in your system. Marijuana, also commonly known as “weed” or “cannabis,” is one of the most commonly used drugs throughout the world. The main chemical in marijuana is tetrahydrocannabinol, also known as THC. Although the effects of THC wear off within a few hours of ingesting marijuana, traces of the chemical can remain in the body for weeks. In turn, the length of time in which THC can stay in your system depends on the drug testing method and ranges between: 30-45 days can fail a urine test60-75 days can fail a blood testUp to 90 days can fail a hair follicle test Article at a Glance: Even though the effects of THC only last a few hours, traces of it can stay in the body for weeks or months.You could fail a drug test between 30 to 90 days after using marijuana depending on if urine, blood, or hair follicles are tested.Unlike THC, hemp and other marijuana-based products won’t make you fail a drug test.Various things affect how long marijuana stays in your system, including THC concentration and frequency of use.THC is stored in fat, so body weight, exercise, and metabolism affect how long it stays in the body. Marijuana Showing Up on Drug Tests 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. The testing method used will ultimately dictate how long THC can be detected in one’s system. Marijuana Detection in Blood Tests: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. Marijuana and Breast Milk:Marijuana can get into your breast milk. Doctors think it is dangerous for a nursing baby to be exposed to breast milk after the mother has had marijuana. Babies exposed to marijuana may even test positive for it in their urine, and may have symptoms like poor muscle tone. Factors that Affect How Long Marijuana Stays in Your System There is no way to know exactly how long THC will stay in someone’s system for a drug test. However, there are different factors however that can impact how long marijuana stays in the body. Frequency of Marijuana Use:Someone who has been using marijuana regularly is likely to have a buildup of THC in their system, meaning it will take longer to leave the body. Method of Marijuana Use:How marijuana is used can have a significant impact on the amount of time it is detectable. If marijuana is smoked, the THC levels in the body will drop within a few hours or days after use. But if it is ingested, the chemicals are broken down more slowly and may remain detectable longer. Marijuana and Weight:THC is stored in the body’s fatty tissue. Those with…

Marijuana Δ 9 -Tetrahydrocannabinol (THC)
Marijuana – Mayo Clinic Laboratories Marijuana Δ9-Tetrahydrocannabinol (THC) Interpretation The parent drug, Δ9-tetrahydrocannabinol (THC), has a clearance half-life of less than 30 minutes and is not detectable in urine. Following a dose of THC, the metabolite typically appears in the urine within 60 minutes, but can take as long as 4 hours. Note: The presence of the major THC-COOH > LOQ indicates exposure to THC within 3 days after a single use, to approximately 30 days in heavy chronic users. Metabolites The major metabolite is tetrahydrocannabinol carboxylic acid (THC-COOH). THC-COOH is inactive and very lipid soluble.

But, how can you do such a thing, especially if you have been using it heavily or often? Several factors affect your drug test results, including level of Tetrahydrocannabinol (THC) in the marijuana you are using, frequency, and hydration. Many of you may have seen some myths online about how to detox and pass your drug test. Maybe some of you have considered using synthetic urine or getting some from a friend. However, you do not want to cheat your way in, because if someone finds out, you could be fired on the spot and barred from employment at that worksite. The best thing to do is find a quality detox method that is safe and natural. If you use cannabis but need to pass a drug test, read on to discover what you can do. Understanding Cannabis/THC Drug Tests First, let us go through a quick rundown of how drug tests for cannabis work. How is it that when we urinate into a cup, have a piece of our hair cut, or offer some of our saliva/blood, they can tell we have been using cannabis? It all depends on the test given. So, let us talk about a few tests and see how they work. Hair follicle testing is a commonly used method of drug testing by employers. A sample of a person’s hair is used to figure out if they have used drugs during a specified time frame. The hair is taken from close to the scalp, and the 1.5 inches that are nearest to the scalp are shipped to a lab for ELISA and GC-MS tests. Once this is complete, the test shows whether the person has used drugs within the past 90 days. Urinalysis testing looks for the recent use of drugs, and it can help employers see if you have used a wide range of substances, including cannabis. The approach used is immunoassay or GC-MS. The latter is far more reliable and looks for a larger group of substances. Urine screening is designed to look for drugs in a shorter duration of time. For example, did you know amphetamines remain in the urine…
