Side note...
I had my long form physical last Thursday. I was alone in the head when I pissed in the container. I then placed the container on one of those turnstile thingies, turned it around a left the head.
We also had a command urinalysis yesterday. Typical... roll your sleeves up, hold the bottle up while waking to the head and the MA conducted his meat gazing collateral duty while you piss.
Physical at NASCCTX...no custody
Urinalysis at NASCCTX...positive control
FWIW, I would think a drug screen is done at the physical but I don't know for sure.
For other dudes....have you ever even heard of a false positive that wasn't backed up immediately with another test?
OBTW, my prostate is fine. Thanks for asking
