The existence of drugs in the hair is based on a simple principle. Drugs are ingested into the body then flow into a person's bloodstream which feeds developing hair follicles. Therefore, small amounts of the target drug or drug metabolite collect in the hair follicle and become trapped in the center of the hair shaft as it grows out from the hair follicle. Average growth rates for human hair are roughly one-half inch per month. By testing for the drugs at different points in the hair shaft center on a piece of hair, a rather precise approximation can then be made as to how long a particular drug has been used. Target drug or drug metabolites cannot be washed, bleached or flushed out of the hair structure because the residue is chemically and structurally stable for a long period of time. Also there is no chance of sample contamination or manipulation. A gas chromatography/mass spectrometry (GC/MS) laboratory analysis of the hair is required to accurately provide the historical use record. Generally it takes about 5 days for drugs to show up in a person's hair and will be detectable in new hair growth for up to 90 days.The collected specimen is hit with a barrage of electrons creating a cation, ionization then accelerated by an electrical field and strained through a receptor that only allows certain particles to pass through. This is then forced through a magnetic field that has a controlled strength. The specimen and the field are oppositely charged creating a deflection of the particles that are then forced through another receptor and into a collector. The operator controls the electrical and magnetic fields so that the mass of the cation is promptly verified. Every compound has a specific weight and charge and can be identified by these properties. It is very easy then to determine the presence of drug metabolites and confirm drug abuse by the subject.

Get a haircut if you're that paranoid. Your hair has grown out in two months. Your system should be free of any residuals by now anyway, unless you're still taking the Valium on a regular basis. If that's the only reason your company would have to fire you, you will get a chance to present your side of the case. If they are just looking for an excuse to get rid of you, good-bye!

if the drug test is serious then i would take the time to get the documentation. if the doc done his job it should be documented on your hospital records what you took so you should not have to get ahold of the actuall dr. who knows what shows up sometimes sesame seeds can show up as certain drugs.

Won't show up on a drug test if it was 2 months ago like you said.

tell the person that administers the test exactly what you said here. you can get a copy of your records from the ER that you went to. go by there and ask for it. by law they must release your records to you.

there are products available through magazines like High Times for a pre test shampoo, but if one Valium is all that's in your system (hair tests are good for 1YEAR) then i would think you could tell your prospective employer and it wouldn't be a problem

like the other person said, they aren't necessarily checking for Valium, unless you had a major high dose, it probably won't show anything anyway.

A lot of places have you fill out a questionnaire when you have your test done. It will ask you if you've taken any medication, for what and when.
