I am a First Responder, I get drug tested every few weeks.All my test in the last year have been good{ about 13 tests}All except my last one.I was told that I tested positive for Benzoylecgonine{Cocain},I don't do illegal drugs,and the say skin contact won't cause a positive result. I just started taking bodybuilding supplements,testoserone boosters,muscle recovery powder and weight loss pills,along with Mega Men ripped vitapaks. I am also on Plavix,allopurinol,Bystolic and crestor.Could any or a combinatio of theese cause a result like this?
