DRUG TESTS NO PROOF

Are you aware that you better be dead on the money with, "Letting your own
kids do drugs would be new low" (Editorial, Sept. 1), because the same sort
of thing could possibly occur that just happened in Missouri?

It was reported that a truck driver who was involved in a fatal accident
had traces of amphetamines, marijuana and barbiturates in his body. Guess
what? It was a lab screw-up, or so they say. No drugs. Oops.

You want to be very careful about using drug tests as a basis for these
glaring, eye-catching headlines, because drug testing doesn't work very
well and when they do these multiples, looking far all kinds of substances,
they're downright terrible.
