Employers and Lawyers! Do you want a better way to tell If your employees or clients have a drug abuse problem? Maybe the hair follicle test is the way to go! The drugs that are ingested circulate in a person's bloodstream, which nourishes the developing hair follicle. Trace amounts of the drug become entrapped in the core of the hair shaft in amounts roughly proportional to the rate of ingestion. These trace amounts of drugs remain in the hair as it grows out from the head at a rate of approximately 1/2 inch per month. Drugs are stable in the hair for long periods of time therefore creating a drug history, unlike urine where the drug residues can simply be flushed out of the system.
