I helped a friend deseed a couple of ounces of killer sativa. Didn't smoke eat ingest any, but I did this bare handed. Found out I have to take a pee test Tuesday, the full blown lab kind. Will I pass a (cop) told me a while back thc can go though the skin. Is this true? Should I be worried. I haven't smoked in 3 years and can't believe I'm in this situation. If I fail I'm through in the career field Im in, for life. I will go on a national registry. Anyone have any ideas.
