In spite of this, I found the remains of a marijuana cigarette (a
roach) in the bathroom of our shop - only used by employees who were on
the program. Somehow they were passing the random tests - meaning they
had figured out a way to beat it. Truth is, I know exactly who was
high on the job - it was obvious from the quality of the work.
However, I couldn't have him fired for it - he was passing the tests.

Passing a **** test is not that hard!!! You can buy dehydrated urin, they
make kits out of IV bags and 9 volt heating pads that hold real urin and
getting clean urin only cost about $40.00 or if they have children then most
just have their children **** in a jar.

Most people that self medicate or use for recreation don't do it at work
anyway.
