Hydrocodone drug test?

My school started doing a HAIR drug testing test. If I took maybe one pill every week how long wold it take to get our of my hair follicle



Hydrocodone drug test?

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 easily washed, bleached or flushed out of the hair structure. Consequently there is little possibility of sample contamination or manipulation. Gas chromatography/mass spectrometry (GC/MS) forensic laboratory analysis of the hair shaft from an individual can achieve highly accurate drug test results and provide a historical use record. Generally it takes approximately 5 days for drugs to show up in a person's hair and will continue to be detectable in new hair growth for several months.

WOW, your school has a lot of money because that is very very expensive but it stays in your hair for a long long long time...it's trapped in the follicle and unlike other systems, it doesnt regenerate the old hair just makes new....
