Hey guys I have been offered my dream job at a hospital but I am worried I may fail the urine drug screen. My test is one week away and I have stopped using for 13 days so far. I was a very heavy user of concentrates (multiple times per day) for about a year. I am 6'2" and 170lbs. My local smoke shop sells a 5 day Everclean clease. Would this help me to get clean? I cannot unfortunately use synthetics or a friends because I will be at an orientation meeting at the hospital for a few hours beforehand. I have also heard of using flush-free niacin to help pass a drug test. This offer came from nowhere or I would have stopped way earlier. Any advise on methods to try? I am nervous to dilute too much because the hospital is doing the testing not a 3rd party diagnostic lab. Any advise helps, thanks!
