I took a drug urine test and just before the test I drunk an monster energy drink and the came back as methanphinemes and the question is can the drink actually cause the test to read that if I have never done that before

But if I have never taken anything like that the could it be a faulty positive ir a faulty equopment

Monster energy drinks are actually notorious for false positives. Mostly of THC though due to a combination of riboflavin ibuprofen (an unlisted ingredient).

J9 is right you need to inform them that you drank that
