I a person is taking a drug test (oral swab drug test) and used two bags of herion and took one suboxen pill, would it show up in a test if its has been 14 days since usage. how far can a swab test detect usage, if the person hasn't used in 14 days. would it show up in a swab oral test. The person hasn't done drugs before, but wants to know if it will show in this type of test.
