“Compared to other drugs, marijuana has the longest detection time, up to months, because the detectable chemicals stay in the body’s fat cells,” explained Nicolas Rossetti, manager of clinical services of Mobile Health, an occupational health center that conducts about 200,000 drug tests in New York City each year.
Cannabinoid metabolites can remain detectable in urine even after long periods of abstinence. One study found traces of one metabolite, delta 1-THC, in urine as long as four weeks after use.
Also, cleanses and teas may alter the amount of creatinine in the urine, another measure that drug tests look at. Abnormal creatinine levels can indicate contamination, according to Rossetti. This means the tester could assume that you attempted to cheat on your drug test.
But what exactly are they flushing out, and how long would it take to happen naturally?
“This flushing of the kidneys can lower the specific gravity or density of the urine,” he added, “and a low specific gravity indicates contamination on the test, and the specimen could be discounted.”
- metabolism and eating habits
- exercise routine
- body fat percentage
- frequency and quantity of marijuana use
The main metabolite these drug screenings look for is called THC-COOH. This substance is stored in your body fat.
THC can be detected in your blood, urine, and even in your fat cells. The length of time THC remains detectable in the body depends on several factors, including:
“Cleanses and teas can lower THC levels through their diuretic properties. They make individuals urinate a lot, which technically washes out the kidneys,” said Rossetti.
When you smoke or consume marijuana, you can feel profound and immediate effects. But even once those effects are gone, marijuana metabolites remain in your body.
Workplace drug tests typically involve urinalysis (testing your pee) for metabolites. Metabolites are a byproduct of a substance after it has been processed by your body. When you consume marijuana, the tetrahydrocannabinol (THC) levels in your blood stream will immediately increase. As your body cleanses the THC out of your blood stream, metabolites are left behind.
If you’re truly panicking a day or two before your test, it might be worth your while to try a same day cleanser from a company like TestClear.com (available online). Such products temporarily target the urinary tract to flush metabolites to give you a brief period for which to give a clean urine sample, meaning you could technically pass a drug test in 24 hours.
To figure out if you are ‘clean’ for a drug test and how to get weed out of your system, you need to be able to determine the following:
Forget detox pills, detox programs or detox kits! A normal healthy, in shape person can rid their body of toxins in 4-6 weeks with a great diet, water and plenty of exercise. Obviously, those with a fast metabolism, lower water retention and overall low BMI will be able to do this faster.
The primary method of passing a urine drug test is to dilute your urine enough where it will be below the 50 ng/mL threshold. It’s a simple as that, but with a hitch. Drug testing labs are on the lookout for diluted urine samples. So in order to be an effective technique, you need not only dilute your urine, but to mask the fact that your urine is diluted.
Creatinine is a chemical waste product produced by muscle metabolism. Creatinine is naturally occurring in the human body and is one method labs use to determine if your urine is diluted. It has a half-life of three hours, so no reason to start taking it more than a day or so before your test.
As we just mentioned, THC and THC-COOH store itself in fat cells, no matter how often or little you use. As a result, the more body fat you have, the more THC and its metabolites will be inevitably stored.
There is no reason to start drinking excessive amounts of water weeks or days before your test. It’s a waste of time as it only temporarily dilutes your urine. Your best bet is to drink 2-3 liters throughout the day before your test, and then around 1-2 liters several hours before your test. Don’t drink too much water though, as it can be dangerous. Start with 2 liters max and be sure to know your limits.
When determining how much THC is in your system, you must take the frequency of consumption into consideration, first and foremost. Do you smoke once a month, once a week, everyday? When you do smoke, are you only taking one hit or enjoying an entire joint (or two)? Obviously, the more frequently you use (and the actual amount you consume), the more THC and THC-COOH will accrue in the fatty tissue throughout your body.
Whether you’re applying for a new job or trying to hold on to the one you’ve got, passing a marijuana drug test can be an important step. Here are several tips on how to clean THC out of your system, starting with a weed detox.
