For the "
I ate a cookie at a party that made me feel weird" excuse.
Yeah. You'd basically be at 0 ng/ml in 3 days.
Even the home test kits that you buy off the shelf a Walgreens have a threshold built into them.
I had an ex girlfriend that applied for a promotion at UNMC that required a urinalysis. She got the promotion and was scheduled for urinalysis 2 days after that.
She was worried because she smoked the weed 2 or 3 times a week. I bought a couple tests from Walgreens that has the cup with the paper strip in the lid and had her pee in the cup first thing in the next morning (i.e. first piss of the day/non-diluted) and it said she was negative.
She passed (negative) her official urinalysis spectrometer test 2 days later.
