Have you ever heard about drug hair screening? If you think it is impossible to use hair samples to test for drug use, then you must have lived in the previous century. A hair strand test is typically conducted to test for the presence of alcohol and drugs in the human body. In this kind of alcohol and drug test, a small sample of hair is used in identifying specific substances that might have been used by the subject. A hair strand or follicle test can only measure prohibited substances and the metabolites they produce only after the substances have been processed by our body. Once the substances have been processed, trace amounts of its metabolites are spread into different parts of our body, including our hair follicles, through our bloodstream.
