Drinkers Need Not Apply?
Researchers are developing tests that can detect traces of alcohol in urine for up to five days, in blood for up to three weeks, and in hair for even longer. The Scotsman (based on an article in New Scientist) reports the tests "could let a GP know if someone is a light or heavy drinker and tell investigators if a driver or worker involved in an accident was drunk at the time, even if they were not tested until days later." They also "could attract the interest of employers and insurance companies."
Assuming that employers do start using these tests, will they insist on complete abstinence (as with marijuana) or simply try to weed out problem drinkers? It's possible, I suppose, that teetotalers, on average, make better employees. But I doubt it.
