Werner Baumgartner pioneers a hair-testing technique to test for the presence of drugs. Whereas urinalysis can detect substances injested inj the last seventy-hours [except marijuana, which can be detected up to four weeks later, this new method can detect past drug use going back over several years depending on the length of the hair being tested. Persons who have used drugs at one time and then quit can be revealed by this method.
