|Myths & Facts|
Determining how long does weed stay in your system, hair, blood & urine has become a hot topic.
When someone is facing a drug test for marijuana, they want reliable answers.
Now that 24 states have legalized or decriminalized recreational marijuana use. Also, many more medical marijuana, testing is a big issue.
Urine contains high concentrations of THC. It also has a longer detection period than many of the other types of tests.
Detection is based on key factors, including individual’s body type, metabolism rate, amount of marijuana used and frequency of usage. How long marijuana remains detectable depends primarily on the type of test and frequency of usage. Types of tests, include;
The Bottom Line – How Long Does Weed Stay in Your Urine System
This chart show the general rules to apply for a drug urine test. As noted, the primary factor is the frequency of usage.
The active ingredient in marijuana is THC. As the liver breaks down THC, a studies give a better idea about the answer to this question., known as THC-COOH, is produced that stays in the system long after the effects are gone. This is the chemical a urinalyses detects. Recent
This is based on what to expect in terms of THC-COOH being detected in the urine. Here are the detection rates according to frequency of usage;
- First time user is detectable from 5 to 8 days afterwards
- Occasional usage is detectable from 11 to 18 days
- *Regular user is detectable from 30 to 45 days
- Daily users is detectable up to 90 days
*regular use constitutes 2 to 3 times a week
Key Factor – Frequency Of Use
Pharmacokinetic information regarding cannabinoids, specifically tetrahydrocannabinol (THC), indicates the body following inhalation of marijuana smoke rapidly absorbs these chemicals. The primary psychoactive chemical in pot, THC is by nature lyophilic, i.e., readily distributed to adipose (fat) tissue, as well as the spleen, lungs and liver. Cannabinoids are then released by organs and fat tissue into the bloodstream, where metabolization gradually occurs.
Blood tests for pot, while they are a good indicator of recent use, are administered less frequently due the invasive nature of obtaining a sample and the involved expense.
- A regular marijuana user will have THC in their bloodstream from two to seven days
How much THC makes its way into the body and bloodstream depends on three primary variables—how deeply the user inhales the pot smoke, how long they hold it in their lungs and duration of a puff.
According to certain studies, THC can be detectable in the blood for up to 25 days after smoking one joint.
Factors Affecting Detection
The reason it is so difficult to determine just how long someone can be positively detected for weed in their system is marijuana is fat-soluble. Fat-soluble means marijuana (THC) is stored in the fact cell of the body. Here are the primary variables for determining how long weed stays in your system for any type of test;
- Body Fat
- How Much is Smoked
- How Often It’s Smoked
- Metabolism Rate
Hair significantly differs from human blood or saliva when it is used for drug testing because hair provides a much longer window of detection.
- In fact, depending on pigment content of hair strands and THC content of marijuana regularly smoked, THC may remain detectable in hair for up to one year or longer.
However, results of hair tests for pot cannot be used to determine when a user last smoked marijuana. In addition, concentrations of THC and other chemicals in pigmented hair are 10 times higher than concentrations found in non-pigmented hair.
Hair follicles bind with THC for longer periods, up to seven days after a single use.
- However, studies have shown testing hair for traces of THC can cause false positives because of secondhand exposure to marijuana.
Law enforcement in many parts of the country have started administering saliva tests to drivers they believe might have been using marijuana.
- THC has a very short lifespan in saliva, but will test positive within about an hour of ingestion and can last about 12 hours.
Be aware that while the U.S. Department of Labor allows on-site saliva drug testing, saliva drug testing is not approved by the U.S. Food and Drug Administration or the Substance Abuse and Mental Health Administration for use with Federal Mandated Drug Testing/DOT.
Although saliva taken from the mouth for testing is quickly turned over inside the mouth, it should be noted that any “rinsing effect” possibly interfering with a positive marijuana drug test result will only persist for two or three minutes. Re-equilibration of THC/cannabinoids within the mucous oral tissues occurs rapidly, which may no longer produce a false-negative test result.
- Meant for “on-the-spot” type drug testing, saliva tests can detect THC up to 24 hours only after smoking one marijuana joint.
How to Get Weed Out Fast — Myths and Facts
While there are products on the market that purport to cleanse your urine, there is no real way to get weed out of your system fast. Flushing your system with fluids will dilute your urine, but won’t necessarily remove the THC-COOH from your body. It simply takes time.
All these numbers are unique to different individuals. It is likely that marijuana testing kits will be improved in the very future due to the greater accessibility of the drug. It will be harder to avoid testing positive especially for regular users.
The technology behind blood, urine and hair testing for THC and other illegal drugs has advanced significantly since testing became widespread in the 1980s.
One of the biggest myths perpetuated today about passing a marijuana drug test. It is passing a test may not be possible if someone has smoked one joint within 30 days.
Flushing the body by fasting and drinking only water may also not remove cannabinoid chemicals from tissues. Nor will consuming certain foods, herbs or vitamin supplements warrant a negative marijuana test, especially if marijuana use was recent and particularly heavy.
The one fact that is certain in regards to getting marijuana out of your system in order to pass a drug test is that only long-term abstinence guarantees a negative marijuana drug test result.
Drug Testing – The Law
As American society eases the legal restrictions on the sale and consumption of marijuana, it’s critical to remember that potential employers are not necessarily changing their drug policies. Many companies require a drug test before hiring new employees, while other businesses, depending on their field of specialty, randomly test their staff.
- Coming up positive on a marijuana drug test might be grounds for termination.
Abstaining from marijuana is the only stress-free and foolproof way to pass a drug test. As an added benefit, this will avoid the negative health-related side effects. These can include breathing problems, depression and addiction among others.
