Researchers at the Institute of Forensic Medicine Freiburg, Germany conducted a study that revealed an ugly truth about testing hair follicles in order to determine whether or not an individual has consumed cannabis. As it turns out, said method of testing is not a valid process for making such a resolution.
In fact, the study’s researchers deduced that “any interpretation of varying concentrations (of THC) along the hair shaft in terms of time-resolved patterns of use may lead to false conclusions.”
How about that?
This particular finding carries great significance, especially when considering the fact that a large number of companies use this type of testing to screen potential or current employees for drug use.
Not to mention that this allegedly failed method of testing is used as common practice in cases where child protective services (CPS) is attempting to conclude whether or not your children are able to remain in your custody.
In addition, the researchers arrived at the judgement that “∆9-tetrahydrocannabinolic acid A (THCA-A), the biogenetic precursor of THC, is found in the hair of persons who solely handled cannabis material.”
Considering the grave repercussions one could potentially be faced with after testing positive for cannabis consumption the processes of drug absorption into human hair is in critical need of scientific assessment, according to the study’s researchers.
With an estimated 125-227 million cannabis consumers internationally, cannabis is reportedly the illicit drug showing the most prevalence in regards to what companies and services such as CPS are searching for when testing individuals for drug consumption.
And as it is with most studies regarding cannabis, the researchers that conducted the study in question concluded that further evaluation is pivotal.
I’m not trying to split hairs here, but I think it’s high time to reform the drug screening process that’s so widely accepted in the United States.
