“There’s a reason drug testing isn’t universally conducted or required for law enforcement officers: false positive results”
Maybe you could tell that to the judges who convict people all the time because of drug tests. Or, folks who are convicted for DUI. Or the folks who get probation revoked because of drug tests etc...
Apples and oranges. You’re describing very different circumstances, reasons, and outcomes for undergoing those tests. I’ve been there, pal. Never go out of your way to place yourself at the mercy of the lab techs.
