How Long Does Weed Stay in Your System?

How Long Does Weed Stay in Your System? By Sera Jane Ghaly, Herb.co

How long does weed stay in your system? Here’s the answer!

The amount of time that weed stays in your system depends on the user and how frequently they smoke. As you continue to consume cannabis, THC accumulates in the body. The more you consume, the longer it will take to clear out. How quickly you metabolize THC as an individual will also affect how long the chemical stays in your system. There are other factors involved, too, such as how you are being tested. Given these variables, here is how long cannabis stays in your system:

THC in urine

The most common way to test for THC, the primary psychoactive in cannabis, is via urine testing. Urine testing is the cheapest method and has a long detection period. Urine and other tests do not test for THC itself, but rather for a THC metabolite called THC-COOH. The presence of this metabolite means that the body has processed the chemical.

The length of time will vary depending on how often you consume the herb. THC is stored in fat, and therefore accumulates in the body over time. The more you smoke, vape, or eat the herb, the longer it will be detectable in urine.

In general, here’s how long cannabis can be found in your system:

  • Single use: up to 8 days
  • Frequent use: up to 15 days
  • Regular use: up to 30 days
  • Heavy use: up to 45-77 days

As a guide, if you’re a regular consumer, chances are THC will remain in your urine for up to a month after stopping. This is also the most likely way you’ll be tested for weed in your system.

THC in saliva

THC lasts the shortest time in the saliva. This is the method most often used by road police in checking for drugged drivers. THC metabolites will show up in your saliva about 1 hour after smoking and can remain positive in saliva for up to 24 hours after a single smoking session. In regular consumers, this number can reach up to 72 hours.

Since THC accumulates in your system, most heavy consumers are recommended to wait for one week before taking a saliva test. For quick reference, here’s a cheat sheet:

  • Single use: up to 24 hours
  • Frequent use: up to 72 hours
  • Chronic, heavy use: up to one week

THC in hair

Though there is a debate on whether or not hair testing is actually accurate, cannabis is thought to have the longest detection window in hair. All standard hair tests look for the presence of drugs over the last 90 days.

Since hair grows at a fairly standard rate, laboratory technicians will test a short hair sample taken extremely close to the scalp. This sample will provide a record of your overall health and what you’ve consumed over the past three months. What the technicians will look for depends on what was ordered in the test.

Cannabis metabolites show up in hair after about seven days post-consumption, but hair testing for cannabis is not very common.

THC in blood

Some recreational are attempting to prevent driving under the influence of cannabis with roadside blood testing. However, blood testing for cannabis is not extremely common. THC and THC metabolites do not stay in the blood for very long. Instead, the cannabinoid likes to quickly find itself a nice, fatty spot to land.

In general, here’s how long you can expect to test positive for THC in the blood:

  • Single use: up to 24 hours
  • Frequent use: up to 3 days
  • Regular use: up to 1 week

How to pass a urine test

Unfortunately, there is no certain way to pass a urine test, especially if you are a heavy smoker. There are products like detox pills, and detox drinks that can be purchased solely for the purpose of cleaning urine. Some even go as far as to use synthetic urine to pass a test, which can be risky.

Many people attempt to pass a urine test by drinking water to dilute the system. If urine is too diluted, however, you risk not passing a urine test. Though there is no scientific evidence to back these claims, many desperate consumers rely on the fruit pectin method to clean out THC metabolites.

  • Mix fruit pectin with an electrolyte drink like Gatorade
  • Drink at least two hours before a urine test (and possibly a day or two before as well)
  • Follow with a bottle or two of water and some B vitamins

The theory behind this is that the fruit pectin is a naturally occurring fiber that makes more THC exit through the bowels, not the urine. However, it’s always important to stay safe and do everything in moderation. There is no foolproof way to pass a urine test, and many detox methods may actually make you sick.

The best way to pass a urine test is to stick safely and generously to the time guidelines!

How long other chemicals stay in the system

When compared to most substances, cannabis stays in your system for a very long time. In general, here’s how long different substances will show up positive in a urine test:

  • Amphetamines: up to 2-3 days
  • Alcohol: up to 5 days
  • Cocaine:  up to 2-10 days
  • Phencyclidine (PCP):  up to 7 days
  • Opiates (including heroin): up to 2-5 days
  • LSD: up to 2-3 days
  • Psilocybin: up to 5 days
  • Ecstasy/MDMA/Molly/Sass: up to 1-3 days

In blood and saliva tests, expect traces of these substances to be present for up to 24 hours. As mentioned above the standard hair test will check for a 90-day history of substance use.

Drug testing is a standard part of life for many in the working world these days. However, because of the varying detection windows for these substances, it is easier to get away with having a problem with amphetamines than it is to be a cannabis smoker.

Given the technology that is available, shouldn’t there be some leniency towards the frequency of use with cannabis? It is legal in some states and countries now, after all.

In fact, after legalization, if drug testing is not altered, the risk to the workforce is extreme. With 13 percent (one in eight) of US residents admitting to regular cannabis consumption, demonizing cannabis consumers in the workplace could result in a giant loss for local businesses.

Cannabis stays in the system longer than almost all other chemicals in the body because it accumulates in body fat. However, everyone knows that you´re not necessarily high 12 hours after use. The best advice to those that are afraid of the ever prevalent urine test? Stick to jobs that don´t require it!

How Long Does Marijuana Stay in Your Saliva?

salivaDrug tests are an unfortunate reality of many workplaces. However, you can consider yourself lucky if you’re a cannabis consumer who has been hired for a job that only tests for saliva (a swab test). Compared with a urine test, or an even more invasive hair test, marijuana leaves the saliva much quicker.

The presence of tetrahydrocannabinol (THC), a compound found in cannabis, is what most tests are searching more. If you’re a daily smoker, studies have shown that in most instances it should be completely out of the system after 72 hours of abstaining from using cannabis. In some instances, a daily smoker can pass a test in a shorter amount of time. In most all instances, though, 72 hours is enough time for the THC to leave the system.

However, in some rare cases it can take up to a week for cannabis to leave the saliva. It never, however, will take longer than a week.

Factors:

Below are some of the factors that will effect how long THC does stay in your saliva:

  • Potency: Unsurprisingly if you consume cannabis with a high percentage of THC, it’s likely to stay in your saliva longer.
  • Frequency of Use: Other than potency, this is the most important factor in determining how long THC stays in your saliva.. If you only smoke once a month or even once a week, you very well may pass a saliva test after 24-48 hours of abstaining. If you smoke daily, it will likely be out of your system after 48-72 hours.
  • Metabolism: If you have a “fast metabolism”, you’re body is likely to flush the THC from your saliva quicker.

By comparison, marijuana can be detected in the urine of a daily smoker for up to two months. When it comes to a hair follicle test, THC can be detected in some instances six months or longer after someone last use marijuana.

How Long Does Marijuana Stay in Urine?

How long does marijuana stay in your urine? What about saliva and hair? And how do you pass a marijuana drug test? Here’s a look at what the science says.

marijuana drug testWhen conducting a marijuana drug test, companies often use a urine test. There are several factors that determine how long weed stays in the urine.

Here are a few:

  • THC percentage of the cannabis being consumed
  • The BMI of the person consuming the marijuana
  • The rate of consumption (how often they smoke)
  • How fast the consumer’s metabolism works

 

With this in mind; here’s what the research shows in regards to how long marijuana stays in your urine:

  • If you consume marijuana once, it should be out of your system in 5 to 7 days.
  • Cannabis will stay in the system for 10 – 20 days for those who consume it a couple or a few times a week.
  • For heavy consumers (5 or more times a week) it can stay in the system for 30 to 65 days.

 

Saliva and Hair Tests:

Two other popular methods are saliva tests and hair tests. Saliva tests are the least invasive; if you’re a daily smoker, studies have shown that in most instances it should be completely out of the system after 72 hours. If you smoked cannabis only once, it will likely be out of your system in 24-48 hours.

air tests, on the other hand, are far more invasive. Cannabis can be found in the hair up to a year after last consumption. Many companies have stopped using hair drug tests, however. Part of this is due to research released last year which found that hair tests can have false-positives for marijuana “because of transfer through cannabis consumers, via their hands, their sebum/sweat, or cannabis smoke.”

How do I Pass a Marijuana Drug Test?

The safest and most effective way to pass a urine drug test for marijuana is to abstain from consuming it; if you’re a heavy smoker, this may mean abstaining for two months or more.

Another option is to do a Google search for “marijuana detox” or “drug testing detox”. Here you will find a plethora of options for cleaning your system and clearing your urine; we highly recommend reading reviews first, however, as some work much better than others.

Another option is to dilute the marijuana in your urine by drinking massive amounts of liquid. This may work to shorten the amount of time the THC is in your system. However, it’s not magic and won’t allow you to pass a test if you’ve smoked recently.

If taking a marijuana saliva test, abstaining for a few days should be enough for even heavy users. If you can only abstain for a day or two prior to the test; suck on the sourest candy you can find for a couple hours beforehand.

If taking a marijuana hair test, there really isn’t much you can do, unfortunately.

 

THC-COOH:

THC-COOH is the main secondary metabolite of tetrahydrocannabinol (THC) which is formed in the body after cannabis is consumed. Most drug tests don’t test for THC; they test for THC-COOH.

The reason this is an issue is because THC-COOH can stay in the body for longer than THC.

What about CBD Consumption?

Standard drug testing tests for THC metabolites, not CBD. This means that consuming CBD will not make you fail a drug test; that is so long as it has had all of its THC removed; or if it’s hemp derived (meaning it will already have virtually no THC).
