The amount of time your body retains traces of marijuana depends on a number of factors, including how often you smoke and your metabolism rate. These factors and the frequency of smoking are key to finding out how long does the THC stay in urine.
“Urinalysis” (or urine testing) is the process of testing urine to detect and assess a wide range of conditions, including substance abuse. Recently it became increasingly common practice for employers to require that employees undergo this type of test regularly.
How long does THC stay in your urine after the last time you consumed weed? The only correct answer is: it depends.
THC, or tetrahydrocannabinol, is the chemical responsible for most of the marijuana's psychological effects. A urine test does not measure THC directly; instead, it measures the amount of a different compound called THC-COOH. This chemical is created when THC is decomposed in the liver; THC-COOH stays in the for a prolonged period of time—nо one can say exactly for how long exactly a urine test for marijuana is likely to yield a positive result. This caused by the fact that rate of THC metabolism varies individually.
According to the National Drug Court Institute (NDCI), someone who consumes weed often—or for the first time—will most likely test positive within a three day period. After four days, though, the threshold should be below 50 ng/mL.
If you are a pothead, it is most likely to test positive for around a week after last use. According to studies NDCI, that most users are likely to pass a urine test at the 50 ng/mL threshold.
According to a 2002 study, if there is a 50 ng/ml cutoff for the detection of cannabinoids in urine, it would be impossible for an everyday user to a get a positive test result after a ten day period since the last puff.
More recent studies show, however, that hard-core cannabis smokers can sometimes test positive for THC traces, even after a ten day period. In some cases, a urine test is positive after one month since last consumption episode. There are even some examples of positive tests results after 67 days since the last weed use.
You may find a number of urine cleansers on the market, though most are at best useless, some can even be dangerous.
Drinking great amount of water is one the best-proved ways to detox your body, as it simply dilutes anything you have in your urine. On the other hand, your urine test might be rejected due to the fact that your urine is too diluted. Still, this might buy you some time before another test.
