to be sure, take 500mg niacin (dietary supplement that flushes the body, trust me you'll feel it and plenty of water on a daily basis and stop the niacin one week prior to UA so it will not show up in the ua (as minnesota government lab test trace niacin and mark it as a dilution method.)
Niacin is a myth. It does nothing to pass a U/A.

There is no drug testing device that tests for niacin. Whoever told you this has no clue what s/he is talking about and needs to do some serious brushing up on research on drug testing. Because if they had done their research, they'd discover that there are no drug tests that test for niacin, and that the labs check the creatinine and specific gravity to determine if a person drank an excessive amount of fluids, which causes the "too-dilute" result.

if you still feel uneasy, buy a $200.00 ua drink. (one's that say double your money back guarantee, WOULDN'T SAY IT FOR NO REASON)
Detox drinks are an overpriced "Dilution method in-a-bottle". You can spend $200 on the magic potion and not accomplish anything different than you would with just vitamins and water.
The so-called "money back guarantee" is not of any insurance that the snake oil will work. Often, when the consumer fails the test and tries to exercise the guarantee, the consumer is told that they:

- "did not follow instructions therefore the guarantee is void"

- "cannabis is illegal and our products are not to be used on lawfully administered drug tests, therefore the guarantee is void"

In summary, "detox" products are a big scam. They exist only to capitalize on the "war on drugs" by seperating the credulous and ill-informed from their hard-earned cash. Cannabis users are already victimized enough by the "war on drugs" without these vulturing scam artists jumping into the mix.
