Hello, PLease help ! I am 21 years old, Skinny build (about 5'11" and 150 lbs with high metabolism) I used to frequently sniff oxycontin. I sniffed about 65mg today and before this was completely clean for 10 days. I have urine drug test (5 panel and the version that specifically tests for oxycontin; so 6 panel if that's what it is called). My drug test is in 20 days. If I eat well and exercise frequently will I pass? It is a pre employment screening and I am very nervous about failing because I really want/need the job. Please help me out here I would really appreciate it, I have chronic anxiety and just need some peace of mind!!
