I doubt it, Done. It is a screening device to screen OUT substance-free folks from having to have a urine analysis. The idea being - why pay for a UA for the clean ones. It screens IN anyone who needs further testing.
So likely, you would be screened IN, but then if you take a reliable UA test, you will have the same results (I presume you can get a UA test that differentiates between Wellbuterin and other amphetamines?).
Sounds like a good device for a large company like a trucking company or restaurant that has been paying to have ALL employees screened on a regular basis.
