How A Marijuana Drug Test Works

Detox Advisor — Mon, 26 Apr 2010 15:16:33 +0000

Have you been smoking marijuana recently? Have you found out about an upcoming marijuana drug test? Have you figured out yet how you will be able to pass it? Many people don’t know the answers to these questions. They continue using illicit substances right up to the day of the test, and then they wonder why they got a positive result on the test. They don’t realize some substances stay in your system for a very long time. If you only use marijuana on special occasions, it stays in your system for at least a week. For long use over time, it may stay for up to three months.

Marijuana Drug Test

Marijuana drug testing can be done with the hair or the blood. Marijuana stays in the hair for up to three months. It can be detected in the blood twelve hours later. You must be very careful in knowing when your place of employment will be testing for marijuana usage. Saliva testing can also be done for detection of marijuana. It will usually show up about an hour after you inhale it. It can also linger for twenty four hours at least.

Marijuana Drug Testing

They do have screening tests that you can purchase online or at a local pharmacy to see if your test results would be too high for your employer. May people take these tests every week to make sure they won’t get caught in case their place of work pulls an unannounced drug test. This can set the user on a destructive path to keep his superiors from finding out what he has done. Random testing is a big favorite of corporate America. With the recession happening at present, we don’t need many workers going off the deep end because they are using illegal and illicit substances.

Hopping up your metabolism may help get the marijuana out of your system faster. Flushing your blood system may be the thing to do. Drinking plenty of water will help as it will dilute the blood a little and the urine a great deal. This will help you get a “Pass” on the marijuana drug test. No one is wanting you to be caught, but they want to help if there is a problem of any kind. Many employers help with addiction and will see you get the proper help you need if you just ask. They realize some habits are hard to break.

Workers who are found to be a false positive will have their sample tested elsewhere to be sure. The standard value for the high end of marijuana use is around 45-50 nanograms per milliliter. Taking Ibuprofen may interfere with the marijuana blood test. So get yourself ready for a bad day if you are using illegal substances. They will bring you down to nothing and won’t give anything back in return. They are all users after all. That is how they get into these predicaments.

The best way to keep yourself off unemployment’s doorstep is to abstain completely. No use of marijuana is tough for anyone. They will still probably find a way to get from one place to another. Many people don’t realize the nature of the marijuana drug tests, so they ignore the rules. No More Tests, everyone will be tested on a swinging daily basis, and they need to make sure nobody could argue that discussion.

What You Need to Know About Drug Testing in Schools

Drug testing is quite common when a person is applying for a job at a company that wishes to be known for having a drug free environment. If a person is arrested for a drug charge, it is common for drug testing to be part of a person’s punishment and/or probation. But what about drug testing in schools? Do you feel that this will keep your child safe? Will it help prevent your child from using drugs at all? Learn what you need to know about drug testing in schools so you can then make an informed decision regarding your child.

Drug use is universally a problem. Unfortunately, younger and younger children are using drugs. What can we blame for this increasing drug use in today’s times? We could blame television and movies, the glamorization of drugs. Perhaps we could throw a bit of blame toward the media and the celebrities whose pictures are splashed across headlines every time the word drug can be used. When it all boils down, the two main factors that may influence whether or not a child will experiment with drugs is prevention by his or her parents or guardians and peer pressure.

While it is true that a parent can not keep their eyes on a child at all times, it is also very true that a parent can use methods to be very well aware of their child’s whereabouts and activities. Even single mothers can know what their child is doing, with whom and when. It is when a parent lets down their guard and chooses the easier way out of “my child would never” there is not one child in this world that can fit into the category of “never”. There are too many determining circumstances. Too much can happen when a child is alone with their peers. No matter what has been said in talks to discourage drug use or what the child has been taught regarding negative effects here is always the “What if”. And this “what if” is where drug testing comes in.

What you need to know about drug testing in schools is that it is guided by very strict rules and regulations. This is not done to take away any freedoms. Most parents will agree that this is a great method to keep track of a child and to ensure that they are safe from drugs. Not only will your child be tested so that if testing positive, intervention can be done to keep your child away from using anymore; but also child that are abusing drugs can be given treatment options so that they are not tempting your child with drugs. The school becomes a safer environment, your child is safer, and any child who is using is given an opportunity to receive help. This is a win-win-win situation.

If you have any concerns about a false positive reading, rest assured. Most tests are done in four distinct steps and a second test is usually part of this method. A child is asked to offer a collection, this is usually done by a urine sample; a painless and common method. The container will be immediately sealed so to eliminate any mistake of mixing up containers. If a reading comes back positive, it is re-checked to be sure of the results. The second test is usually a more thorough and detailed test. Then, a doctor or nurse will review the results to be sure that there are no prescribed medications that could affect the result. Urine testing negative are eliminated and disposed of.

THC Drug Tests

The chemical called THC produces a number of physiological changes. It can cause a drug user to develop a dry mouth. It can increase the heart rate of the person who has taken-in the THC. It can depress a person’s coordination, balance or reaction time. It can wipe out some of the person’s short term memory. Still, a THC drug test does not search for evidence of those physiological changes. A typical THC test uses existing assay techniques to detect the presence of THC in fluid from a test subject. Blood and urine are the two fluids that are most often tested.

The THC drug test looks for evidence of the chemical that scientists refer to as delta-9-tetra hydrocannabinol. Over time, THC works its way into all of the tissues in the body. The THC drug test can call for collection of urine, saliva, hair or blood. All four of those tissues have the ability to retain THC for a set period of time. All four of those tissues can be removed from the body without conducting a surgical procedure.

While marijuana contains many different chemicals, scientists point to THC as the mind-altering element in pot. THC can lower a person’s perception; it can affect his or her ability to maintain sound judgment. Employers look to the THC test as a way to limit the use of marijuana among their employees.

The amount of THC in a sample of marijuana reflects a number of different factors. The marijuana plant produces more THC under certain weather conditions, and when grown in specific types of soil. The time of harvest affects the amount of THC in the marijuana plant. Not every type of marijuana plant makes the same amount of THC. Not every plant part contains the same level of THC.

Sinsemilla, a popular type of marijuana, is made from the buds and flowering tops of the female marijuana plant. It has a THC content of 7.5%. The results of THC tests reveal marked changes in the THC level for other forms of marijuana. In 1974, most marijuana had a THC content of 1%. By 1994, that level had risen to 4%.

The THC test relies on the fact that THC is a fat soluble substance. When inhaled or ingested by the marijuana user, THC is stored in the body’s fat cells. As the body burns fat, the THC becomes released from the fat cells and enters the blood stream. Fat cells generally store THC for two days. Once filtered through the kidneys, THC shows-up in the urine. That takes place about three days after the drug user has enjoyed his or her marijuana-induced “high.”

The passage of blood through the kidneys does not remove all of the THC in the blood stream. The blood can retain THC for a period of two to four weeks. A THC test done using human blood is the most sensitive type of THC test.

Every THC test demands the use of immunoassay techniques. Test makers produce a teat kit that contains monoclonal antibodies. Those particular antibodies have an affinity for THC. The kit equipment thus picks-up THC in the blood or urine.

The test makers obtain antibody-producing cells from the spleen of a mouse, and fuse them with mylemoma cells. The test makers can thus produce a large amount of the desired monoclonal antibody. That monoclonal antibody then becomes an important element on the devices that are used to conduct a THC test.

Hair Drug Test and Its Validity

A hair drug test is a specialized kind of drug test that attempts to determine the presence of certain classes of drugs in the hair samples of a subject. The hair sample used for conducting the test may be taken from the head or other body part, in some cases extracting the hair from beneath the skin. A hair drug test can trace the history of substance (drug) abuse in a subject to as far back as six months. A number of points of criticism have been raised against hair drug tests, questioning their validity and social implications for certain ethnic groups. However, the procedure is increasingly being used in the US for various purposes.

Drug tests are performed to determine whether a certain drug, or any of its metabolized traces, exists in a body part or product of a person. A hair drug test is conducted to determine the presence (or absence) of a particular drug in the hair samples of a subject. The primary significance of a hair drug test lies in its high degree of accuracy; usually a typical hair drug test would trace the subject’s possible abuse of a particular drug to as far back as six months, especially for subjects who keep long hair. This is because the suspected substance of abuse gets encased in the hair shaft and is preserved there, making it easier for the tester to detect it even months after its use.

The process of performing a hair drug test is fairly simple. Hair samples are taken from any part of the subject’s body, preferably from the head, and tested at a chemical laboratory for detecting the presence of different kinds of drugs including marijuana, cocaine, opiates (morphine, codeine etc.), and amphetamines (e.g. Ecstasy). It is not very useful for subjects to try to get a negative result by shaving their head because hair samples from other body parts also provide evidence of drug abuse. Further, in case hair is not available, hair follicles can be tested for a particular class of drug without affecting the accuracy of the test. This can be much more painful for the subject on account of the extraction of hair follicles out of the skin.

A hair drug test should always be performed at an accredited chemical laboratory, showing whether the drug exists (positive) in the hair or not (negative). The result also shows, in case of a positive result, whether the subject is an occasional or high-level user. Efficient laboratories usually provide the test’s result in two days after receiving the sample. It is important not to mix hair from different body parts in a single sample i.e. hair collected from head are not to be mixed with that from the body. Also, samples collected from hairbrush, or some other object of use, are not recommended for testing.

Conducting a hair drug test of prospective employees is a growing trend in the US despite the cons of hair drug testing. While advocates of hair drug test stress that the results are not affected significantly by usual treatments like shampooing or dying etc., some studies claim that hair washed with certain brands of shampoos show a significantly lower concentration of drugs. Hair testing procedures have also been criticized for being racially biased, particularly against Africans. Further, hair tests may not prove sensitive for certain kinds of drugs, e.g. pot. Despite these points of criticism, the trend of using a hair drug test for determining a history of drug abuse is on a rise in the US.
