The bottom line is that ACCURATE drug testing (the sort that determines
the individual is currently impaired, and not fooled by poppyseed
muffins and who knows what else) is EXPENSIVE. Unfortunately, we do
not hold the drug labs liable for their errors. If they were not
protected from liability from their mistakes, they would soon go out of
business and the problem would solve itself.

The bottom line is that the THREAT of being popped positive on a random
drug
test seriously deters drug use. In the field of professional aviation,
that
is a good thing.

And heck, if you have to wrongly destroy a few careers and wreck some
families, it is worth it, eh?
