What are some things you have seen people do to cheat on the UDS? Do you ever use hair or saliva testing?
Pour water into the cup and give it to us as urine.
Dilute their urine with water.
Drink lots of water or soda to dilute the urine.
As UDS requires a certain threshold of drug concentration, dilution can work.
Other things that they can do - take an oral supplement meant to hide MJ in the system.
Add a chemical to the urine to dissolve MJ metabolites and hide it.
Using a prosthetic penis attached to a urine sample tied to their leg. You can buy these on the internet in different colors.
There are the excuses - I just went to the bathroom before you asked me. I can't pee now.
One guy was a quad in a w/c. He said he doesn't urinate. I pointed out his leg bag. I asked if we could have a sample of that. When he reluctantly agreed, he wrote under that "SUD" when asked what that was he said "Signed under duress" I fired him then and there. I ran the sample anyway, and he was doing coke, MJ and amphetamines.
I tell anyone who claims not to be able to pee that we will offer them water, coffee or soda of their choice, and they can wait in the waiting room until they can urinate. They are told if they leave the waiting room for any reason, they will no longer receive opioids. Many leave anyway.
Another one, a paraplegic, did this routine, left, and then came back the next day with a urine sample in hand for me to test. It gave me a good laugh. He could not understand what was wrong with that idea.
