Could Ibrufen And Vitamin B 12 Medication Can Show Positive For Marijuana?
Hi, I took a urine sample and a hair follicle test and a lady called me and said i failed for amphetamines and marijuana in the urine but nothing in the hair and im prescribed to adderall and ibuprofen 800 and take vitamin b2. Cant these throw a false positive for marijuana? I havent smoked it since i was 16 and im 25

No, but there are a certain number of false positive tests. The hair test is done much more reliably and has fewer false positives. the fact that the more sensitive but more reliable test was negative (hair) shows you didn't actually use. They probably know this already, and you probably are not in trouble.
The false positive with urine can just show up. They do not need to be due to anything in particular.
