Marijuana is one of the intriguing medicines in the world today. The controversy surrounding his drug has led to disputes between the law and the community. Where recreational marijuana has been legalized in a number of states, there are still strict rules governing its production and utilization. This is why marijuana drug testing is common and uses a number of different tests to ascertain whether you are consuming the legal levels of medical marijuana or not. There are a number of drug tests that are used by the authorities aimed at detecting different chemicals. Some target THC, whereas others tend to look for by products. Here we describe the many tests used for marijuana drug testing, along with their limits and importance.
Marijuana is highly detectable and can be detected using urine analysis, saliva tests, and hair analysis, even up to several weeks. The results from these tests can provide details on whether the user takes marijuana within limits, whether he is a chronic user and the time since he last took it. The theory behind these tests is that marijuana is fat soluble. Hence, its molecules tend to deposit into the fat stores. This leads to chronic levels of marijuana which makes marijuana drug testing so easy. Typically, it can be detected in the urine for 3-10 days. However, if the person is a chronic abuser, the marijuana is present in the urine for as long as 3 months even after stopping is of marijuana.
As we mentioned previously, marijuana can become embedded in the body which leads to its chronic secretion. So, drug tests for marijuana are categorized as historical or recent intoxication. Over the years, hair follicle testing and urine analysis were the tests of choice for marijuana. It targeted the THC-COOH molecule, which is not psychoactive and only indicated if the person had taken medical marijuana in the past. These tests are also able to detect past use irrespective of present consumption. This is because the THC molecule accumulates in hair follicles and fat stores over the time leading to the chronic release of these molecules.
On the other hand, marijuana drug testing that employs present levels of the drug includes serum and saliva tests. These tests check for the presence of active THC molecules. However, there are still confusion regarding the limit of THC in the blood. One reason for the discrepancy is the fact that THC levels remain elevated even when the person has not recently taken marijuana. The marijuana drug testing will show him as if he had taken the drug. The level of THC that is considered to be the limit is 5nanograms of THC in 1 milliliter of blood.
Now that you know the different tests employed on marijuana drug testing, let’s focus on individual ones. Urine analysis is a quote common marijuana drug test. A sample of the person’s urine will be required. This is then sent over to the laboratory and the THC levels are tested. In the urine the THC limit so the 50 Nanograms per milliliter of urine. If the levels are within this value, the urine is called negative and the person is free to go.
However, if the test is positive with levels above 50 Nanograms per milliliter, then the urine is retested using advanced equipment like mass spectrometry to make sure. This test then using a limit of 15 Nanograms per 1 milliliter, which is much more accurate, if the levels are found to be higher than this, the urine is labeled positive for marijuana. So, now the question is, for how long will the urine remain positive?
THC can be detected in the urine for a period of about 12 weeks. The exact time, however, dep Ends on how much you use it and how often you use it. Even if you have stopped using marijuana, you can test positive till 30 days.
This makes use of the hair cell. This is much more accurate than the other tests, but it is also much more expensive. Plus, if the person used marijuana even for a short while in the past it will show up, but this doesn’t necessarily mean that he was outside the legal limit. This raises questions regarding the reliability of this test. Then again, its advantage stands, this is one test that allows you to detect marijuana for months on end. Plus, you can use hair from any part of the body.
This test is directed towards finding out the present dose or levels of marijuana in the system. It is usually implied in car accidents or work reports to detect if the person was under the effect of any drug. The blood test comes back positive for 6-24 hours, making it quite a reliable test to detect if the person was under any kind of influence when driving. On the other hand, regular users of marijuana can test positive for times extending up to a week.
This is an instantly applied test much like the breathalyzer test for alcohol. It is one of the newer tests for marijuana. It usually uses a strip that detects whether there are marijuana components or by products in the saliva which indicate marijuana use in the past 24 hours. This makes it a great test for instant evaluation by police officers. The test detects marijuana if it’s above the legal limits and is an indicator of current marijuana influence.
All of these tests point to the many ways that the law enforcement agencies use to detect marijuana. Although the drug is legalized in many states, there is still an impending risk of addiction and abuse, or so the government thinks. Hence, there are certain limits in place which allow you to use medical marijuana safely. The point of all these tests is to enforce a balance in the society. Even though the law has relaxed certain limitations, it still has the higher control regarding the matter. Marijuana drug testing does not mean that you can’t use the drug itself. Instead, it only emphasizes the safe and responsible use of the drug for the betterment of the society.
