All You Should Know About Detection Times For Hair Drug Test


History of Hair test?

Hair testing has its origin a long time back before the urine testing module emerged. In fact, when you consume drugs, it is embedded on your hair and then on to the strands where they stay for a considerable period of time. Hair is known to have a growth rate of 5 inches per month. So let us understand the logic as if your hair was 18 inches long, and when the strands of your hair were tested, then the obvious fact is that you may have consumed drugs say three years ago.

But no need to press the panic button as the ends of the hair is never tested. There is only a standard parameter of the test and that is 1.5 inches, which are cut from the root. The end of the non-root is totally eradicated.

What is a hair follicle drug test?

Quiet often one comes across the term hair follicle drug detection times and are confused on what it is? It is basically an examination where a small sample of hair is taken and used to determine whether an individual is into consumption of specific drugs. The hair follicle test measures the drug molecules along with specific metabolites that are produced after the drug is embedded in the human body.

It is known to cover a period of 90 days, but variations are bound to happen depending upon the growth rate of your hair. The hair is to be cut as close to the scalp and as already mentioned 1.5 inches of hair should be used for testing purposes. In certain cases the time frame may extend more than 90 days, and all depends upon the growth rate of the hair.

There is a different school of thought that emerges on whether the body hair can be tested in the same manner as the hair on the heads. One needs to understand that the growth rates of body hair as compared to the hair on the heads is a bit slower. Another question is what happens if a person is bald? The hair can be collected from different regions of the body except the pubic hair part. In cases where no amount of hair can be collected then urine testing is the only option left. Drugs can be typically detected in the region of 7 to 10 days after its usage as hair follicle drug detection times is normally less during this time.

Hair Follicle Drug Test Detection Times

The drug test detection time to detect marijuana in your system depends largely on the frequency and dosage of weed usage, the kind of test employed and your metabolism levels etc.

Based on inputs from many people who have performed the hair follicle drug tests in various labs, the detection window can be categorized into mainly:

  • MarijuanaSingle Use – Detection is doubtful
  • MarijuanaRegular Use – Drug residues can stay on for 90 days
  • Amphetamines – Drug residues can stay on for 90 days
  • Cocaine – Drug residues can stay on for 90 dyas
  • Heroin, Opiates – Drug residues can stay on for 3 months
  • PCP – Drug residues can stay on for 3 months

If you had marijuana only one time, then you don’t need to worry about the hair drug test, as you can easily go undetected, as there won’t be much residues in your blood stream to get passed on to your hair. Hair tests are most likely to detect only regular users and occasional users can go undetected with the hair follicle drug testing.

But if you are a regular user of marijuana, then definitely the residues would’ve mixed with your blood stream and there is every chance that some residues get placed in your hair follicles and can stay there for up to a month.

Long Hair or Short Hair

Many think that people will long hair will get detected as it would have more residues and people with short hair have less chances of getting detected. The truth is, it doesn’t matter if you have long hair or short hair, it only matters how much of weed is in your system, as people in the lab use only 1.5 inches of hair from the root and any other hair is cutoff.

Understanding the odds

The rules of drug testing vary from country to country and from a specific state to another. Job aspirants are screened for drug tests, if it is a low paying job. The private employees avail more freedom when it comes to drug testing procedures.

Understand which drugs the employees screen and which not

Opiates or cocaine are the common drugs that are tested, but inhalers or anabolic steroids if found in your hair samples is not a cause to worry.

Gain knowledge about a hair test process works?

When you consume a drug, the active chemicals present in them will circulate in the body. When the body processes the drugs, the chemicals accumulate in the hair follicle. When a strand of hair grows, the chemicals will be deposited in the follicle. During the course of hair tests these samples are looked for.

Stop the drug use?

As and when you are aware that a drug test is round the corner, stop usage of it completely. Before you are looking for jobs cease the drug usage. For example hair tests can detect the use of certain drugs like cannabis even after 90 days of its consumption. Before three months of planning to enter the job market stoppage the usage of all forms of drugs.

If one is desperate then opt for a home remedy

If you have used drugs in the last 90 days and a hair test is round the corner, then the best chances of clearing the test are to use a commercially product or try the home based tests. Though these methods are not proven on scientific basis, they are all outcomes of individual success stories.

Hair Follicle drug test is one of the most unreliable testing methods, as most of the casual users who use roughly 1-5 times a week go undetected and only regular users who take weed daily have a higher chance of getting detected in the hair follicle drug test detection.
