Glad I could add a data point for you. My personal feelings would be
legalize pot. Though I'd apply the same workplace and driving rules
on it that are in place for alcohol.

IF you did that, are tests accurate to tell you if the person smoked
last night, or if he had a small amount before he came to work that
morning, and got tested two hours after he got to work that morning?

It just seems like it would be tough to impossible to enforce, to me.

Nope they are not and you are right it is would be a problem. My bet though
is that a mouth swab or some other sort of test to check for estimated time
of use could be developed.
