I've only taken morphine once 11 years ago and had an allergic reaction, yet i tested positive for morphine on a drug test. how is this possible?

False positive: There is a good possibility that you had a falsely positive test that is usually ruled out with a second test used to confirm the screening test. Make sure you inform testing agency of all drugs, prescribed or over the counter and supplements you take as some may cross react and cause a falsely positive test.
