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.

They do mouth swabs in some situations. Apparently (says an industry
source) there's some margin of error; somebody who used that day and
would have failed a UA passed the swab test. This woman worked for
a company that sold a UA test kit, a masking agent to beat that kit,
and about six months after they released thta they released an
advanced UA test kit that detected the masking agent.

Interesting racket.

Here's a tip for everyone. NEVER accept one of the quickie tests that the
results show up on the panel on the cup. They are worst than useless. Both
false positives and negatives at about a 30% rate. I bring this up because
of the comments about masking agents like URinLuck. (Gotta love that name.)
A test sent to a proper lab will send back an "adulterated" result almost
everytime.
