I got some home test kits from the local Walgreens to get a feel for what a solid 10 days of abstinence would do for me. I had smoked a small bowl of my own home grown every day for 10 or so days. After 10 weed free days, I still flunked the drug store test. I am 5'8" 135, not too much fat. If this test is not supervised, ie a pre employment test, substitution like "Quick Fix" might be the way to make sure that you won't test hot. I have read that one month of abstinence should be enough for most people to test clean, even the obese. I think if the weed I'd smoked had only been schwag, I would have passed.
