OTOH, if you smoke weed and your first sample came up positive on GC/MS, assume the split sample will also be positive.

The observer has to watch the urine leave your body and enter the sample cup. As a trained observer, believe me when I tell you I want to look at 200 guys' dicks even less than the 200 guys want to show them to me. But that's what you've got to do.
