Hair drug testing
In hair testing, around a hundred strands of hair, one and a half inches, are taken from the back of the head and are examined to test the presence of drugs in the body. Follow the website cleardrugtests.com/how-to/pass-a-hair-follicle-drug-test to get the correct information on how to pass a hair test. Hair from the chest, arm or beard can also be used. This method is very useful because any drugs remain in the hair for months and especially if the person has a slow hair growth. On the other hand, hair drug tests are costly, and it takes a long time to process the samples. For these reasons, most employers do not use this method.
Passing a hair follicle drug test
You cannot pass a test if you do not know the process involved. Anytime you consume any drug; it will end up in your blood. The blood revolves around your whole body, including the head through your blood vessels. The drug gets filtered through the hair and will stay there for close to ninety days. This method is the most accurate test for long-term drug use.
Stop using drugs ninety days before the test
This is the one way that you can be a hundred percent sure that you will pass the drug test. If you do not take any drugs within that duration, your hair will test negative, and you will pass the drug test. However, remember that this test is very difficult to fool because there are no toxins that can lower the drug stains in the hair. You should, therefore, be very careful when using these methods.
