Because of this, hair testing is often referred to as a ‘lifestyle test.’ However, that long look-back window is not necessarily the best way to detect a single instance of drug use in scenarios like post-accident testing. Instead, hair testing is more informative of a repeated pattern of drug usage during the broader detection window. The detection of a single drug-use event is complicated by the extremely small percentage of the total dose incorporated into the growing hair during that single use event.”
