How long before drug use shows up in hair follicle drug test?

Blood vessels surround hair follicles underneath the scalp, so drugs in the bloodstream incorporate and bind to the hair follicles underneath the scalp.

It takes approximately 3 - 5 days for hair with drugs incorporated or bound to the hair follicles under the scalp to reach the top of the scalp to be collected. based on the average rate of head hair growth.

Head hair grows an average of 1/2-inch per month (~1.3 cm for those of you who prefer the metric system).  The standard length of hair laboratory tested about 1 1/2 inches from the root end (~ 3.9 cm) or 1/2-inch times 3; therefore, hair analysis reveals drug use for a time span of approximately 90 days (3-5 days after drug use).

Drug tests may show drug use, but many times drug use alone falls short of the proof necessary for the government to make their case if you face a Dependency, Neglect, or Abuse case or a drug crime charges.
