Hello from JustAnswer.

How much did he smoke before quitting?

Is he taking any medicines, including any over the counter medicines?

It will take me some time to type an answer.

Expert:  Dr. D. Love replied 11 months ago.

It is very unusual for someone that smoked daily to still have a positive test after 60 days. Even someone that is a heavy daily user will usually only be positive for about 30 days after quitting. It is always possible that someone could be an exceptionally slow metabolizer, but it would be very unusual.

It is actually statistically much more likely that he is having a false positive. There are many different reasons that false positives can occur, and we cannot identify the specific reasons in many cases. I ask about other medicines because one of the common reasons are over the counter anti-inflammatory medicines, such as ibuprofen or naproxen. Since he is not taking any medicines, it is possible that it could be related to something in his diet.

While I can say that in someone that has certainly quit marijuana use for 60 days, it is statistically more likely that these are false positives, the proof of this would require performing a confirmatory drug test, such as a GC/MS. These confirmatory tests cannot be done at home, so it would be necessary for the test to be done in a reference laboratory. You can contact a local lab and ask how to get tested. They may require an order from a doctor, but many labs may do the test without a doctor's order (although you or he would be responsible for the bill). If he gets a confirmatory blood test and it is negative, then that is proof that these positive screening tests are false positives.

If I can provide any additional information, please let me know.

You are welcome. Your family doctor would be able to get the confirmatory test done.
