all they guys at work stick it in the microwave everyday i don't do it cause i the the nuke might kill some of the stuff in it

where I work we are always getting called for random urines and what works for us I plenty of water the night before work and plenty All day giving a weak sample usualy they won't ask again due to the cost of retesting. either that or we keep the urinator on hand for any Monday test for coke user and weekend worriors, in 3 years of employment only know 2 guys who failed cause they thought they were clean and it was dust anyways,

i normally stay away from "help me pass a drug test" threads.. But..
You will come out better by drinking a gallon or so of water the morning you wake up of the day of your test.. after you finish the gallon and piss about 4-5 times and your pissing clear, you will have a good chance of passing.. This is confirmed true.. however it is in no way fool proof. my guess is its about 30-50% efffective
