Take This Leak and Shove It
Reader Ari Spanier points to a story about how the blood, sweat, and tears (forget the toil) of federal workers may soon be subject to more stringent drug-testing procedures. Consider it a full-employment program for those in what might be called the effluvia industry.
Saliva testing, done using a swab that looks much like a toothbrush but with a pad instead of bristles, is best at detecting drug use within the past one or two days.
Hair testing, in which a sample about the thickness of a shoelace is clipped at the root from the back of the head, allows detection of many drugs used as far back as 3 months.
Sweat testing, in which workers are fitted with a patch that is worn for two weeks, is used to screen people who have returned to work after drug treatment.
