Stimpy21,

I have not yet seen or heard of a deterrent to counteract swab testing. FBR was the expert on this subject and he is no longer an active member of this website. This rest of us mainly deal with Urine Analysis, so we don't have much experience with it. I did some checking on home swab tests and they are around $10 a piece. If this is something you want to experiment with, it would greatly enhance the forums here on swab testing.
