The test could have created a false positive, which is known to happen a little less than 2% of the time.

If you hang around people who are smoking it you can inhale enough of the smoke to get a positive reading.

False positives are possible. Second-hand smoke is a possibility. Advil and ibuprofen are known to cause false positives for marijuana. Or you went to a faulty lab.

Marijuana won't show up in a blood test, unless used immediately before. Amoxicillin can create a false positive for cocaine abuse, but if this is the case it should be easy to avoid trouble with proof of use of the drug.

Hi Joe-thanks for yo?

Hi Joe-thanks for your question. THC, or delta-9-tetrahydrocannibol, is an active metabolite (breakdown product) of cannabis and is what leads to the effects of marijuana. When positive in the blood or urine, it typically indicates recent marijuana use (chronic users or slow metabolizers will have positive results for longer). However, there are some potential explanations for a positive test in someone who has not been exposed to marijuana-this kind of result is called a false positive test and is due to a metabolite of another substance reacting with the THC test. Ingestion of hemp products or certain medications (anti-acid, anti-nausea, and over-the-counter pain or cold remedies) can lead to a false-positive test. If you have not used marijuana nor been around someone who has, and you believe this test is a false positive, you should request that the test be repeated-using a different testing method if possible. Be sure to discontinue use of any medications that are not necessary; if there is a question, ask your prescribing doctor.
