I recently had a pre-employment drug test done, the took hair samples from my armpits. The results came back back positive for cocaine. I do not use cocaine, and wonder if a combination of medications, and recent cardiocath done (whatever they used to numb up area before inserting cath), might be the cause for the positive result. I have also read the having diabetes may cause a positive result. Your help with this matter is greatly appreciated.
List of medications are the following,
Metoprolol
Metformin
Plavix
Ramipril
Aspirin
Fish Oil
Isosorb
Diltiazem

Thank you,
James
