Can a urine eyeshade detect if a consistent opiate is self used or do they own to do more trialling?

I'm on a prescription called vicodin es and I used to be a heroin user. I'm currently on probation and enjoy to take urine drops. I freshly was curious to know can they notify the difference?Can a urine eyeshade detect if a consistent opiate is self used or do they own to do more trialling?
Just make sure you explain to them before you pocket the test. You will probably want to own a prescription with you too. That means of access they know you are not lying.
Bring the prescription with you.
