Sativa, Killa, and Sensi thank you for your feedback. I've got to tell you that maybe it's just me because I am usually a very thorough person, like when I was out of weed and would take a paperclip to the inside grooving of my bowl for the resin, but I have done prelimenary test on myself using these methods and have failed. Well good news today was I got my test rescheduled for later this month so that gives me a little extra time to exercise my ass off and try and flush myself out. Have a good one.
