"Marijuana" in blood and urine - how long will the drug test be positive?

  • The most common test for cannabis in the body is the urine test
  • The detection time is highly variable
  • The metabolism of each individual is different

Drug tests in the body are perhaps inevitably part of our society. For example, whether you are a student or an employee, if you dislike your teacher or boss while running self cannabis or simply taking cannabis at your leisure, your boss can pull you a ruthless weapon at any time - a drug test.

What now? WITHyou remember to remember when you last used cannabis and how long it will stay on your system. Two weeks? Three? The folk knew usually speak about 30 days. But the real answer is not that simpleespecially because of the many types of tests used, which have different levels of sensitivity and detection accuracy.

In addition, afterwe take into account the fact that metabolism works at least a little differently for each individual and that we also differ in the type and rate of consumption of the therapeutic cannabis , the whole thing gets tangled up.

"No definite detection time exists," says Ryan Vandrey, professor of psychiatry and behavioral studies at Johns Hopkins University in Baltimore. "The time of possible drug detection in the humansystem is very different in most individuals, especially due to the different frequency of use and different volume of substances used. Simply put, there is no way to determine with certainty how long your test will be negative. "

Testhose for drugs - how do they work?

Nowadays, "testers" have an entire array of detectors available - the presence of drugs is therefore able to identify in urine, blood, saliva, breath, or even in your nails.

After apllationcannabisthe level will inevitably increase THC in bloodwhich is then detectable from a few hours to several days. Even though the THC level in the blood drops below a detectable level after a few days, there are still plenty of ways to prove that you are cannabis enjoyed.

THC, CBD and others are by-products of metabolism, more specifically lipid metabolites - stored in the fat stores of the human body. These molecules are then gradually switched offpuppies back into circulation and burned, so it takes the whole process of "cleansing" much longer than with other drugs, especially long-term users. The longest remains of cannabis remains in the hair in which a non-psychoactive THC metabolite called 11-nor-delta9-caboxy-THC (THC-COOH), which can be detected for up to 90 days after cannabis administration, settles after consumption.

Despite the fact thatThere are many different ways to detect the presence of cannabis metabolites that seems to be clearly winning a urine test at school and employment. However, as with the hair test, the urine test does not detect the current THC content but only the THC-COOH metabolite.

Another variablehowever, the sensitivity of the test, or the concentration of THC-COOH, over which the test is considered positive is selected. The most common measure is 50 ng / ml, but the tests range from 15 ng / ml to 100 ng / ml.

How Long Does Marijuana Stay In The Body?

As we mentioned at the beginning, each of us works on a bit of a "frequency", which further complicates the matter. Even people of the same age and gender are very different - it depends mainly on the lifestyle and diet (people with a greater fat supply are slower to get rid of cannabinoids).

For example, according to sthe study of Paul Cary, head of the Toxicology and Drug Monitoring Laboratory at the University of Missouri (Toxicology and Drug Monitoring Laboratory at the University of Missouri), the time of detection rarely exceeds the classic 30 days. Furthermore, one of the older 1989 studies showed a detection limit of maximum 25 days (the assay sensitivity level used was 20ng / ml). In addition, only one of the subjects tested in this study was tested positively after more than 14 days. On average, after 9.8 days, the level of cannabinoids was below detectable levels.

For further clarification we can shareThe study was conducted in 1984. The sensitivity level in this study was set at 50 ng / ml and 40 days was shown as the maximum detection time. However, it is important to note that only 8 days out of 10 subjects had only 13 days to test negatively.

TODaily X Occasional use

"Of course, we need to take into account the frequency of use and consumption of a given individual. Overall, however, it is evident that in most cases a shorter time interval can be expected.Some users rarely exceed the 10-day limit at 50 ng / ml test sensitivity. If the sensitivity is reduced to 20 ng / ml, we can expect a maximum of 21 days, more of which are exceptions. In the case of occasional users, it is rare to cross 3-4 days into a negative test. "

Next, be aware thatcomparing the chronic and occasional types of users, we compare opposite ends of the spectrum. Thus, most common cannabis users fallroughly somewhere in the middle.

"I think these deductions are meaningful. We can count on a maximum of 72 hours for only one isolated use or a truly occasional application. However, for chronic users, 7 to 10 days should be considered." says Ron Flegel, head of one of the SAMHSA programs.

What can affect the outcome of a drug test?

Flegel also mentions the frequent cases of individuals who vary between positive and negative test results.

"Oftenpeople are calling us and asking how it is possible that they had recently passed the testsnegative and suddenly tested positively although they have not applied cannabis ever since. This phenomenon is mainly due to physical stress - the body is dehydrated, causing higher urine concentration and, in particular, fat deposits burning, which also releases THC residues. Thus, one test result may be negative and the next day, for example, after training, be positive again. "

Positive drug testand consumptionCBD

What to expect from a drug test if you only apply non-psychoactive, therapeutic CBD? How long does it remain in your system and is detectable by common tests?

Pif you really consume only CBD you do not have to worry about the positive test result: normal urine tests are only set for THC detection. There is a risk only to patients who are actually receiving large doses of CBD (1000-2000 mg per day) - CBD oils contain traces of THC. Theoretically, the result of the initial test could be positive. However, the next, more thorough THC-COOH test would not be positive.

How to "cleanse" from  THC faster?

If you want to get rid of residual cannabis particles as quickly as possible, you must first stop applying cannabis. The next step is then continuous, sufficient hydration - the more fluid you get into the body, the less your urine will be concentrated and thus your chances of a positive test will be reduced. But beware of too much hydration - if your urine is diluted above acceptable levels, you may have to take the test again.

Next, and probably even more effective, tacticThe quick purging is to reduce the intake of high calorie meals and implement regular, challenging exercises. As mentioned, cannabinoids are deposited in the fat stores of the human body. Exercise and caloric restriction Therefore, you will accelerate fat burning and hence the removal of residual cannabis particles.

Remember, however, that if you start practicing and burning fat from nothing, the primary effect will be to temporarily increase your urinary THC levels. It is therefore necessary to give the body sufficient time to cleanse.
