Greetings. I am looking for work in Southern California and have not smoked or been around smoke for 89 days as of today. I was heavy-set but have been going to the gym and sweatting out as much of the toxin as possible. As a result I lost 50 pounds and have been flushing out my system regularly with water (about half gallon a day since 3 months ago). I took two different home tests last night, both of which are different brands. I came up positive on both. I am floored by the results and am astonished as to how this could be given my length of time without smoke and my exersize. What am I doing wrong. I keep hearing that people are fine after 30 solid days with out weed and here I am still positive? I was a very heavy smoker with some fat around the gut. I have lost most of the weight and haven't had a single hit. Any advice is greatly appreciated. Thank you.
