I have never taken non-prescription drugs in my life, but I have a pre-employment drug screening coming up. I've been doing research to double-check if there's anything that might create a false positive for me. Apparently, I'm on an antibiotic (doxycyline hyclate) that might create a false positive for opiods and a bit of THC. 
I'm going to take my prescription bottle with me to the drug screening. Hopefully it will all work out all right. Please post if you've gone through something similar.
Canada doesn't have to deal with this stuff. They're civilized enough to ban random and pre-employment drug screenings.
