how do you pass a drug test the next day?

Without bringing someone who is cleans piss I would say its not possible man

Drink plenty of water at night and the next day drink a cup of white vinegar 2-3 hours before the test.

it's gross but it has worked for me.

Get a pill box and have someone piss for you in it, and just tape it to your thigh and u should be good, it worked for me

theres a way. went to a head shop and bought this pill- its called the omni soft pill, the lady behind the counter said that she has sold it for a very long time and never gotten a complaint and u can get ur money back if you dont do it right ( you have to take it on an empty tummy ) i didnt use it *it was 45 dollars* becuase i just waited to be clean , so i dont know if it turns ur piss bright yellow , but just drink some water and its fine. it works in 90 min- and last like 7 hours. you can look it up online and its got great reviews. i was going to use it if i didnt pass in time. honestly i would use this before anything else. you can buy it online if u dont have a shop that has it, and you dont have to drink anything nasty or burn up on niacin. but yeah i really hope this helps ya dude, theres gotta be a way for us hardcore stonners to beat the system! haha good luck!
