Can some medicine show up as an illegal drug in a drug test?

From Wiki:

"In Canada, codeine can be sold over the counter only in combination with two or more ingredients, which has resulted in the prevalence of AC&C (aspirin, codeine, and caffeine)"

I'm pretty sure Tylenol 3's fall under that distinction but I could be wrong

from: living in Ontario and needing a prescription for T3s

Fair enough, that doesn't necessarily mean that applies for the entire country though. Is it just T3s specifically, or anything with Codeine?

Not medicine and I'm not 100% sure but these things could change your result into a positive for heroine

poppy seeds
(maybe it's just a myth but IIRC a police man confirmed this)

I been told that they can but that is why you have to list all the meds you are taking before you take the drug test.

Jackie, you're alive! In case you haven't heard, your best bud PVS isn't here anymore. Sorry.
