Hair Folicle Testing

Would you submit to a hair follicle test if asked? Unlike blood and urine testing where drugs can be 'washed' or 'eliminated' away eventually, hair follicle tests can determine kind of drugs take, when, and how much. Basically it can be a dive into your past.

According to one web site:

The presence of drugs in hair is based on a simple principle. Drugs which are ingested into the body circulate in a person's bloodstream which nourishes developing hair follicles. As a result, trace amounts of the target drug or drug metabolite are deposited in the hair follicle and become entrapped in the core of the hair shaft as it grows out from the hair follicle. Normal growth rates for human hair are approximately one-half inch per month. By testing for the presence of drugs at various levels in the hair shaft core on a given length of hair, a fairly accurate approximation can then be made as to how long a particular drug has been used historically. Since target drug or drug metabolite residues are chemically and structurally stable for a period of time, they cannot be washed, bleached or flushed out of the hair structure.

So, are you for against them? Suppose you are requested to give samples of your hair at work?

Testing Folicle Hair

Since I don't use drugs of any kind, I would not have any problems to provide the samples but I would do it only if it is extremely necessary and if they are security measures in place.

Hair Folicle Testing History & Civil Business Politics

I have never taken drugs, so have got absolutely nothing to hide. I do however feel that this is infringing on your civil liberties, so I don't think I would allow a hair follicle test to be done. It just seems too far into invading into privacy.

In England, you are on camera wherever you go. The Government have already put into place at certain airports an 'iris test' where you use the iris of your eye to determine who you are, and therefore you don't need your passport to identify you.

In my opinion, I can cope with the iris test, if it cuts down on terrorism, but I do feel that if an employer doesn't trust you enough to the point that they want to do a hair follicle test, then they really shouldn't have employed you in the first place.
