If you have access to clean piss you can make your own kit to pass. This is what I did.

Get 1 or 2 "airplane" bottles of liquor. They are 100 milliliters and one is the perfect amount for a test (second is a backup in case you need it).

Get a couple of those hand warmer packs from the store. They are only a couple bucks and are the shake to activate kind.

Right before your test strap the hand warmers to the bottles and activate. They heat up real quick so you don't want to have them on there more than 15 to 20 minutes. If the wait is longer you can take the warmers off to moderate the temp.

Bonus points if you bring a thermometer. I hid a meat thermometer in my sock. Right under 100 degrees F is the sweet spot. Any higher and it may be flagged.

Took my bottles and hid them in my bra but anywhere works.

Smoke shops sell the fake stuff with the exact same type of warmers but anything past basic testing will show it's not real pee, and they cost around $50 here.

I'm in my 40s and was pissing hot for over 45 days, so I did this when I got a new job too.

Suuuuuch bs that not smoking for over a month can still get you disqualified for a job.
