" Put piss in small, clean, plastic bottle and it was held securely between balls and ass."
Boyfriend did same thing....temp was off 2 degrees.....back to jail.....1 year... probation violation. It all depends where/when/why you are being tested.
Pain management, court, employers who really care ( many don't/Pot )...you will not pass. For every measure you take to fake a pass ( and they know them all) their is a counter measure.
As for a one day cleanse ($$lol). Buy one than go to ( dollar store, Walmart ,CVS) get 2 tests, pee and watch it pop.
If you are lean, consume lots of water daily and workout/sweat a lot you can pass ( generally speaking ) in 2 -3 weeks.
My experiences..... my opinion.
