How did Fentanyl show in your urine when you do not take it?

Fentanyl can show up in urine tests due to several reasons, including exposure to the drug through skin contact or inhalation in environments where it is present. Additionally, certain medications or substances may metabolize in ways that create false positives for opioids. It's also possible that contamination could occur during the testing process. If you believe the result is inaccurate, it's advisable to discuss it with a healthcare professional for further evaluation.
