I had to take a drug test for my place of employment. I tested positive for amphetamine and methamphetamine. the amphetamine is from my vyvannse medication, but Im totally confused as to what would cause a positive methamphetamine reading and I desperately need your help as to any medications that could result in this. I have to send documentation on my medications. I am a nervous wreck because I absolutely love my job and want to make sure I know what I can do to give any information to the lab asap so I don't lose the best job I could ever ask for. please help me asap
