I just peed the other day. It had been 5 months since I last smoked. What surprised me was the automated tabletop urin drug screen analyzer. I believe it's called EMIT DAU. The special testing cup comes with indicators for "adulteration.". It checks pH, Creatinine, temp, and I don't know what else. The cup is sealed with the special lid and placed inside the analyzer where I assume the test strips are electronically read for color change (like a ua dipstick). All results are electronically submitted to the employer within 15 min. All signatures by the employee are electronic. A pretty tight procedure.

Other than a genuine negative urine at the proper temp for substitution I really don't see a way to cheat this system. Sensitive to XX level and highly specific for the metabolites being tested. I did an early morning test but not first morning void. I should've waited for a negative confirmation from my employer but I didn't....so paranoia set in. There could've been a failed transmission, a read error, power failure...who knows.

I've smoked every day since...but I keep feeling like I'm doing something wrong!!
