Does psyllium help you pass a drug test?

Psyllium is normally used in the treatment of constipation as it forms a "bulky stool that is easy to pass." This means that it helps clump all that runny, liquidy stool in your GI tract so in theory it would be very good as picking up THC metabolites which would be found within your fat cells and also present in your GI tract. However, I fail to see how this would help you pass any sort of drug test as there isn't a feces drug test lol that I have heard of.
