Anybody have any knowledge about these urine drug screens that some doctors are giving these days? I had an appointment with my pain specialist last week so he could renew my medical marijuana card. He ask me to take a urine test and I had no issues with that because other than medical marijuana that he prescribes me I’m recreational drug free and have been for years. Well sure enough my results just came in online and it says I’m positive for norfentanyl. Says coming up positive for Norfentanyl is consistent with the use of fentanyl? Wtf. All bullshitting aside the last time fentanyl was used on me was like 6 months ago when I had my last major surgery. I don’t take anything but supplements and AAS. How the fuck am I supposed to convince him his tests are shit unless it’s actually possible they can detect fentanyl for months after last use? I know fentanyl is stored in fat cells but detecting it in urine months later seems far fetched to me. Anyone else ever have an issue like this?
