The "gold standard" of drug testing is blood or urine
There is no gold standard, it depends on a bunch of variables including cost, the handling time, and detection window. If you want a wider window, a reliable test suddenly becomes infeasible. Blood? Two or three days?
Might as well not test anything.
the colour of your hair and your ethnicity will influence the results
This is bullshit cooked up by retarded burgers because niggers and spiks can do no wrong, or something. Americans are fucking imbeciles always looking to exploit the racial angle in any and every given situation, despite claiming to be a multicultural society that has grown beyond the retarded and arbitrary confines of race.

Yeah, differences does exist, however, such differences have an insignificant impact to the final result.
The big controversy and problem with hair-follicle testing is that the colour of your hair and your ethnicity will influence the results. For example, Sub-Saharan Africans and those of Southern European/Mediterranean ethnicity will always have higher levels of the chemicals that are read to indicate stimulant use (cocaine and methamphetamine), and thus people of these ethnicities are inherently more likely to read above the cut-off.
Inherently? More like infinitesimally likely. The cut-off for these are set differently. For courts, it'll be 500. For other things like public servants and workplaces, give or take 100-150pg/mg.
This is a manufactured poison-the-well type controversy to discredit the test itself utilising extremely fringe statistics. It's an attempt to sound plausible and scientific because the average retard 100-IQ no-degree haver couldn't comprehend tiny or gigantic numbers. GC/MS has been used for literally everything else with great reliability, fast turnover and accurate results.
What was the result? Did they test for metabolites as well?
Was she tested positive for both cocaine and the metabolite (specifically benzoylecgonine) at above cut-off? -> she's likely coping. It doesn't matter if a blood test yielded whatever. The blood test detection window is at most three fucking days. She could snort fat lines last week and the test will yield negative. A week is the time it takes for judge Shlomo Goldberg to sign off some papers. What use does a test like this have in that context?
Above the cut-off for cocaine but no metabolite? -> environment
Above the cut-off for metabolite but not for cocaine? -> environment
She's majoring in social work and goes to university where even the dorknerd Scandinavian prudes go mad with narcotics. It could plausibly be a false-positive or even accidental ingestion. I would also imagine social workers who deals with a lot of vulnerable people in the public are more likely to be exposed to narcotics, resulting in skewed test results. Has she been on an internship recently? Went to any parties?
I cannot find their hair test protocol. Do they test the washing liquid as well?
Seriously, there are numerous explanations to give her the benefit of the doubt, but they chose to chimp out about MUH QWEEEN HAIR DAS RACIZ YTE DEVIL.
Yeah, Agilent is a subsidiary of the Ku Klux Klan, give me a break.
This isn't even the hair test's fault. Why the fuck does social housing require drug tests? That's retarded and ridiculous, what a waste of time and resources. Someone with a home is less likely to do any drugs period, that alone should remove any of these ridiculous requirements for a mother to get a roof over her head, Black or whatever.
It also begs another argument, why don't we just use slightly higher cut-off levels to adjust to these supposed racial/ethnic/fat-fuck/skelly/bleached hair whatever biases people come up with? Make it 600 then.
Ridiculous.
This article from a British law firm is a good summary of the issues with hair-follicle testing. I have a copy of a peer-reviewed journal article somewhere at home, which I presented to the court at the time that I took one of these tests, which I remember made a lot of the same points. Likewise see
this document. A quote from the case law that appears in the latter: "It is particularly important to emphasise that each of the three experts in this case confirmed that hair strand testing should never be regarded as determinative or conclusive." Results from blood or urine tests (particularly the former), meanwhile, are used in criminal courts - with their higher burden of proof - without any hesitation.
The article speculates about numerous pitfalls in the protocol and the druggies in the comments think it should be thrown out.
The same argument can be used to ban cars. Cars kill people and drunk people get in cars to kill people. Cars kill more than guns.
Ban trains. They hunt Indians. Actually no, please give us more trains.
Ban planets, a Sikh terrorist can blow it up or Muhammad al-dirkaallahjihad can fly it into a building.
Ban breathing, you can die from breathing bad air.
The conclusion is fine. Cut-off levels are a lazy way to establish drug use, but it is up to the lawyer to challenge the method instead of throwing it all out, complicating the system even further.
Fact of the matter is we have numerous ways to decrease false results to near zero, when to use them is what everyone should be focusing on.
Skelly's daughter A.R.R. tested positive at more than ten times the cut-off of 500pg/mg. The court document said cocaine, but it could be the metabolite or cocaine. Skelly said they found the metabolite benzoylecgonine.
Either she had >5000pg/mg cocaine in her hair and traces of benzoylecgonine also above cut-off, or she had >5000pg/mg of benzoylecgonine in her hair which simply does not happen with environmental exposure.
Here's my post on environmentally exposed cocaine-in-hair resulting in benzoylecgonine:

tl;dr after over 4 weeks, somehow BE gets metabolised. However, cocaine tests all came back negative or very low, while BE reaches above cut-off levels.
She was tested within a few days after the cops visited, and apparently rubbed an entire bottle of cocaine into her hair. There would have been no time for BE to naturally spawn in her hair, unless she's a walking incubator or... really I don't know. Die skelly.
It's like throwing eggs at a wall. The eggs being arguments to show the test was a false-positive.
