I'm wondering how accurate this calculator might be: Online THC Calculator According to this, I should be about 64 mg/nl this morning. Friday will be 14 days weeks since I last smoked. I'm hoping that I'll hear back about a particular job in the next day or two and, if I do, I know that I'll need to take a drug test immediately. I'm assuming that minimal dilution will drive this number below 50. Ideas? Thoughts?
