I had a pre-employment drug test at Quest, and my friend informed me of the substitution method. I used a condom, my friend's clean piss and the tighty whitey method and the piss was in the right range, but the one thing he didnt tell me was to use a NON-lubricated condom. I discovered this forum and was reading the sub thread, and when i saw that someone had said to "make sure to use a non-lubricated condom" my stomach dropped. I used one of the trojan-enz condoms. I made sure to rinse it off really good, but will this affect the outcome of the test?
