Please write your question hereThis is a unique question and it'll be easier just to start from the beginning. i was a very heavy weed smoker in the past at least 3.5 grams per day for 10 years. i got in trouble and was put on probation with drug testing so i quit smoking. my drug tests have always had faint lines for thc after i cleaned up. During my heavy smoking period i developed large calcifacations (i think that's the word) in my kidneys now I'm constantly bothered by kidney stones. I go to the er a lot over them. but back to my question. I've always had faint test lines for thc but when ever I'm passing my kidney stones my faint lines turn into no line which results in a positive drug test. but as soon as I'm done passing the stones my tests go back to the faint lines and negative tests for thc. is it possible that my heavy smoking soaked into the buildups when they formed and now result in the constant low levels of thc (faint lines) and failing my tests (no line) when I'm passing kidney stones. the only time i fail my drug test is when passing stones. I've looked everywhere for answers but there isn't any testings done for this. so is it possible that its mykidney stones and if so where shouldistart to take care of this
