DETERMINE POT IMPAIRMENT LEVEL

Re "Why fire people for medical pot use?" (Opinion, April 10):
Columnist Bruce Maiman urges employers to treat the use of medical
marijuana in the same manner as prescription drugs and alcohol.

So why don't I, as an employer, treat it the same? Because there are
no clinical trials informing me as to when someone is impaired.

With prescription drugs and alcohol, there is an agreed upon and
universally accepted correlation between levels in the body and levels
of impairment. With that data, we can make an informed decision on how
to maintain safety and productivity in our workplaces.

So instead of beating the same drum, over and over, why doesn't the
pro-pot movement spend some money on objective clinical trials? Please
provide me, and other employers, with a quantifiable level that
guarantees a safe, productive work environment. Oh, and by the way,
make sure it will stand up in court.

Then I can test for a particular level in the same way I currently do
for prescriptions drugs and alcohol. Until then, I am left with
measuring the "presence or absence" of THC.
