How long does weed stay in your system? Unpacking THC in the body

Urine and hair tests have a longer detection window, anywhere from 1–90 days after last use. About 40 to 50 million drug tests are conducted by employers each year, which analyze biological material including urine, hair, blood, saliva, breath, sweat, and even fingernails. When cannabis is consumed, THC levels temporarily rise in the body, which are detectable in blood tests from several hours up to a day after one usage. Although these levels drop significantly after a few days, there are other means of determining recent usage. If you know you have an upcoming drug test, not all hope is lost. Given the current detection windows for standard cannabis tests, it’s likely you will be able to pass a urine test as long as you are not an extremely heavy user and are given sufficient advanced notice.

In the end, you should know when will weed be cleansed out of your system if you’re a chronic user, a skinny woman, a fat man, somebody with over 200 pounds or a one-time user will less than 100 pounds. How long weed — or the presence of THC metabolites — is detectable depends on the type of drug test administered. It’s also affected by your unique physical functions and frequency of consumption. The body processes THC (delta-9-tetrahydrocannabinol), the intoxicating cannabinoid known for creating euphoric, stoned effects in several ways, and is dependent on the method of consumption. THC reaches the organs and bloodstream faster when you inhale marijuana as opposed to ingesting edibles.

It’s also important to remember that “occasional” and “chronic” cannabis users each represent opposite sides of the usage spectrum, and most consumers would likely fall somewhere in the middle. One important factor is also the kind of urine THC tests that are being used. In the calculations above, it was presumed that the detection of THC in urine is being conducted with a standard drug screening test with a 20 ng/ml cut-off rate.

1. New and veteran users may be wondering when it’s okay to drive or take a drug test after ingesting the drug by smoking or eating.
2. Saliva tests can detect THC metabolites for one to three days after consumption or a month if you consume regularly.
3. Long-term effects result in some permanent changes to the brain, such as losing mental abilities and functioning.
4. After use, cannabinoids reach the hair follicles via small blood vessels, as well as from sebum and sweat surrounding the hair shaft.
5. How long weed — or the presence of THC metabolites — is detectable depends on the type of drug test administered.

Although conventional wisdom says at least 30 days, the answer is not straightforward. There are many different kinds of drug tests available, which have varying levels of sensitivity and time periods to detect marijuana in your system. However, blood tests can detect THC metabolites for a few days to a few weeks, depending on how much you consume. Having one or two edibles or smoking once a day may not affect your results in a hair test. It takes time for THC to be stored in your hair follicles and build up. If you used weed today, the metabolites would only show up in your hair for seven to 10 days afterward.

But if your employer tests you regularly and without prior notification, perhaps it wasn’t a dream job after all. 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. The most common cutoff for most marijuana urine tests is 50 ng/mL, but cutoffs can be as low as 15ng/mL and as high as 100ng/mL—each of which result in widely different detection windows. Detectable amounts of tetrahydrocannabinol (THC) may remain in the body for days or even weeks after use. Upon consumption of marijuana, THC is absorbed and stored by various body tissues and organs.

Using cannabis during pregnancy can negatively affect fetal growth and development.

How long does it take to feel the effects of cannabis?

Marijuana, also known as weed, pot, or ganja, is a medicinal plant of the cannabis family. It contains a psychoactive compound known as tetrahydrocannabinol (THC) that has major intoxicating effects. The leaves, seeds, stems, or roots, are mainly used for intoxication purposes. Marijuana preparations are usually smoked in pipes, joints, or water pipes (bongs). Approximately, 11.8 million young adults used marijuana in 2018.

This is because chronic cannabis use will result in THC accumulating in fatty tissues, which will result in a slower elimination of metabolites. Different drug tests for cannabis have different detection windows. In general, detection time will be longer with a higher dose and more frequent cannabis use. Each person has a unique metabolism that processes marijuana at a different rate, further complicating the picture. Even among people of the same gender and age, individual lifestyle choices such as level of exercise and eating habits may also affect the amount of time required to pass a drug test. Those with higher levels of fat content store cannabinoids more readily than leaner folks.

One of the most abundant components in cannabis is a chemical substance called THC, which stands for delta-9-tetrahydrocannabinol. Given these preliminary grains of salt, however, several studies have explored this question over the years, offering some general guidance for those awaiting an impending drug test. Although medications may not be effective in treating addictions, some antidepressant medications help manage withdrawal symptoms and prevent relapses. Sure, there are lots of this kind of anecdotal cases but nobody really likes to risk his or her job with something as serious as failing a drug test. Weed might be great for a number of reasons but THC elimination time is definitely not one of them.

What factors affect how long THC and its metabolites stay in your system?

The process requires opening up the hair cuticles to expose the middle part of the hair follicle where metabolites are stored. The Macujo Method is considered 90% effective to pass a drug test but can be pretty costly. THC metabolites stay in the body for at least 1–30 days after last use. Regular cannabis users may have elevated THC levels even after a period of abstinence.

However, the odds of getting a positive test after just one hit are much lower if you never consume weed than smokers who consume every day. New and veteran users may be wondering when it’s okay to drive or take a drug test after ingesting the drug by smoking or eating. For a drug test to be negative, the body must eliminate THC from the system, as well as metabolic chemicals that have links to THC. People with faster metabolisms typically eliminate THC more quickly than those with slower metabolisms. There isn’t much you can do to speed up the amount of time it takes for THC metabolites to leave your system. Some of these factors, such as body mass index (BMI) and metabolic rate, aren’t related to the drug itself, but to how your body processes it.

Once the THC metabolites are stored in your hair, they will stay there until you cut your hair. When you use marijuana, your liver breaks it down into metabolites. About 20% of the metabolites leave your body through urine, while the other 80% are removed as feces. As the body stores THC in fat cells, regular exercise may help to break fat cells down and release THC into the blood for further excretion.

How do drug tests for THC work?

The by-products formed by the breakdown are immediately cleared via urine. In a chronic user, the excretion rate of THC through urine is less, so it builds up in the liver. We looked into published scientific studies about how long does weed stay in your system. In a 2009 study published in Addiction, researchers monitored cannabinoid concentrations in the blood of 25 frequent cannabis consumers.

Cannabis that’s ingested may remain in your system slightly longer than cannabis that’s smoked. More potent cannabis, which is higher in THC, may also stay in your system for longer. A number of factors affect how long cannabis metabolites stay in your system. Since hair grows approximately 0.5 inches per month, a 1.5-inch hair segment taken close to the scalp can provide a timeline of cannabis use over the past 3 months. In jurisdictions where cannabis is illegal, oral fluid may be used for roadside testing.
