drug/alcohol testing policy: effective?

I think "probably cause" testing only would be more cost effective. The
war on drugs is just one more handout to businesses involved in it.

To this extent, I know a woman whose adult daughter worked for a company who
provided drug-masking chemicals as a urine additive...they'd sell that for
six months or a year, and then release the agent to detect the chemical.
Then they'd sell another masking chemical....

The employee, by the way, smoked pot.
