Even though you're clear now I just want to add that I'm pretty sure the further testing is just to see HOW much of that amphetamine was in your urine and if that is a medicinal dosage then it's alright. If it's too high to be medicinal then you'd be screwed. Also opiates like codeine would be alright anyway since they are OTC.
tomm01 Reviewed by tomm01 on . High Anxiety, seeking input Hi everyone, I am in place to start an internship with a Fortune 500 company pending I pass a drug screen. I took it last week with LabCorp/ChoicePoint. I smoked for the first time in 5 and half months, 25 days prior to the test. I also stupidly took a tylenol 3 (with codeine in it) and 20 mg of oxycodone about 4 and half days prior to the test. In my defense, I didn't know I would be getting drug tested when I consumed these substances, and would never have done so otherwise. Rating: 5
