In brief: Body hair

The growth rates for body are considerably slower than the hair from your head.
Most body hair is replaced in about one year. It is challenging to precisely represent the time period of a standard screen with body hair so substances may be detected in body hair for up to 1 year after the substance left the blood stream. www.ipassedmydrugtest.com/hair_drug_test_faq.asp best wishes.

In brief: Drug test for what??

Some hair turns over slower on various body areas.
Many scalp hairs are years old. It grows 1cm per month. So measure the length and do the calculation.
