Question:
Can taking St. John's Wort cause a false positive on a drug test?
I had to take a drug test recently for a potential employer. I take St. John's Wort as treatment for a nervous disorder. Can that cause a false positive on a urine test?
Answers:
Just inform the technician when you take the test and the St John's wort will be screened out from the rest of the test.
