Tetrahydrocannabinol, as well identified as THC, is the major psychoactive substance established in the Cannabis plant (Marijuana). Testing for marijuana by using urine is now generally applied for random job tests. This is the least expensive of the test techniques.

Labs get the sample and moreover combine it with chemicals or dip a chemical colored test strip into it; or in a few instances they check it more strongly in lab testing tools, according to the kind of substance they are searching for.

50 nanograms of marijuana metabolites for each milliliter describes a “presumptive positive” by NIDA (National Institute on Drug Abuse) licensed labs. So, to pass the test, you don’t require having completely clean urine - you require having a lower than 50 ng/ml of marijuana in your urine.

Tetrahydrocannabinol (THC) is quickly absorbed by inhalation and the gastrointestinal tract. It is almost totally metabolized. The major metabolite is 9-carboxy-11-nor-delta-9-THC, which is established in the plasma, feces and urine all along with other substances. The very low attentiveness of THC perhaps identified in urine during the early several hours, but tetrahydrocannabinol preserves in urine at a noticeable concentration for many days after smoking.

Marijuana drug testing

A predictable 20 million workers are drug-tested yearly in the United States at a rate of more than $1 billion. The body metabolizes THC into about five metabolites prior to passing it into the body’s urine, so drug tests are planned to discover the metabolites in its place of THC. Noticeable amounts of these metabolites stay in the system for some days to some weeks pursuing marijuana consumption, according to the level of consumption.

The most general test for identifying marijuana or any drug is the immuno-assay. In this test, the urine is combined with a solution holding an antibody to particular metabolites. The antibody is generally covered with a fluorescent dye or radioactive substance. The amount of fluorescent light or radioactivity is calculated to decide on the attentiveness of metabolites in the sample.

Gas chromatography/mass spectrometry may as well be applied to test for THC metabolites. GC/MS testing is expensive and that is why most employers prefer the self test kits, generally to discover marijuana. They are very easy to apply. Simply take 5 drops of your urine and drop it into the testing tool. 1-2 minutes later if there are 2 lines, you are clean. If there is just 1 line, this denotes you are testing positive for that drug. In Internet nearly all companies offer an extensive variety of kits from 1 panel to 9 panels. Denoting you can test for up to 9 drugs at one time! Simple to follow directions are certainly integrated.

Cannabinoids originate from dried flowers, resin or leaves in cannabis plant.  The plant contains THC.  The alternate names for cannabinoids include marijuana, weed and pot. The effects of cannabinoids are difficulty concentrating, impaired motor skills, slow reflexes, apathy, reduced coordination and concentration, and dryness of mouth.  Testing for cannabinoids is important for confirming mental and physical wellbeing. Marijuana drug test and Cannabinoid drug test is a crucial element in most of the pre-employment drug testing.

Marijuana is the most widely abused drug in the US.  Urine Cannabinoid testing permitting performance of the test in non-laboratory settings like in probation offices, industrial locations, and schools have been formed and most of them like test for marijuana can be performed without any kind of technical experience on the testing methods.

However, those that are going to interpret the test results should be those that are probably aware of the pitfalls of such test methods.  In cases, where the test results are being used for counseling or in determining the compliance of the patient in abstaining from marijuana then the tests should be determined and interpreted by an expert rather than someone that has no technical knowledge about it.

It should be noted that in some cases of passive inhalation of marijuana the test result is likely to be positive.  So, in such cases a legit and reasonable consideration of the lower limit values for illegal positives should be set in deciding and confirming positive testing for marijuana.

There are test strips available to test for marijuana in single as a single panel drug test or there are also test strips that are made available for testing for marijuana and other illegal drugs of abuse as multiple panel drug tests like single panel drug test, two panel drug tests, three panel drug test etcetera.  Based on the combination of drugs that the company or an individual is interested in having tested they can make the purchase accordingly.

In cases where the test is being done due to non-productivity of the candidate, it is always advisable to be doing multiple panel drug tests because the resultant non-productivity can be related to something that is not just related to marijuana and it can be related to poly drug abuse and sometimes abuse of some other drug other than marijuana.  The positive result of any kind of basic immunoassay is just a yes or no answer and it should be confirmed by alternative confirmatory test methods.
