I do not smoke marijuana and tested positive. I drank an Monster energy drink before the test. Could that do it? I have lost my job and they won't test another sample. I have done 4 home tests since that came back negative

Some of these sites say yes, some say no. You figure the ingredients in them are herbal so I would say some of the herbs could. You can tell the tester what all you have had that you are concerned about.
