Urine and blood tests are among the most common forms of drug testing, but the hair follicle test is quickly becoming the one employers and courts request. The human bloodstream is directly connected to hair growth, making it possible for drug molecules to appear in hair shafts for months or years, depending on the length of strands. Hair follicle tests are subsequently considered highly accurate forms of drug testing.

How Drugs Enter Hair

Any drug that is smoked, snorted, ingested, or injected produces metabolites, or substances formed during metabolism. Metabolites and the drug circulate in the bloodstream, eventually entering the hair follicles, as blood provides the hair with nourishment.

A hair follicle test detects the five drug classes as determined by the federal government. They include marijuana, opiates (codeine, morphine, 6-monacteyl morphine), cocaine (cocaine and benzoylecgonine), phencyclidine (PCP), and methamphetamines (methamphetamine, ecstasy, and amphetamine).

Time Period

Hair follicle tests generally cover a period of 90 days, meaning any drugs ingested during the 90 days would appear on the test. Depending on the sample length, it may be possible to detect drug use over a 120-day period. Some states require a 120-day test.

Close to the Scalp

You can expect strands of hair to be removed from your head as close to the scalp as possible. Standard tests generally require 40 to 60 or more milligrams of hair, or 90 to 120 strands. These numbers are due to the varying thickness of hair. Chest, leg, and armpit hair are acceptable alternatives if you have little or no hair on your head.
