I do realize I should not have been taking my dad‘s hydrocodone. I have discontinued all use and again it’s been nine days since the last dose. I only take my oxycodone 10 mg now. Most of the research that I’ve come up with says Hydrocodone is out of the system in four days. Please tell me if on day nine it should be safe to take my urine screening. That will be almost 10 days without any hydrocodone. I only take the oxycodone now. Please help me or answer if you think there will be no hydrocodone so that I can pass the urine test. Thank you so much for your help in advance
