Hey all, getting ready to pass a drug test so I quit smoking on 3-25. I wanted to make sure I'd pass so I went to a lab to test myself on 4-12 (18 days). Former bowl a day smoker of dank bud, 190lbs, 6', average metabolism, male, ride my bike 2 miles a day.

I took a 5-panel test and to my great surprise I failed the initial screen at 50 ng/ml. They sent it to the lab for additional GC/MS confirmation at 15ng/ml, and I called back the next day and they showed that I PASSED.

How is this possible? I thought the lab test was stricter, hence the lower cut off. Does this mean the initial test was a false positive? Or worse, could the lab test have been faulty? I just want to make sure I'll pass my test, it'll probably come around 4-23.
