Hello, I was in a simalar situation lately, if you would have read my thread you would know about it...
I have to drop weekly at the clinic I go to, well I was a bad girl and I slipped up and used
cocaine.. well I peed in a cup before I did it, I thought I would be able to save the urine, warm it up and take that and put it in my urine cup to be tested...well I found out a few things...first of all urine will go bad after 24 hours, and you have to refridgerate the urine for the 24 hours as well...I was told and found out that if you keep the urine longer than 24 hours then you can actually get false positives and you dont want to go that route..now here the thing, If you stopped using a month ago you should be fine whether you used heavily or not,
marijuana doesnt stay in your system that long...I think your best bet is if you are telling us the truth and you havent used for 30 days or so...If I were you I would drink water like crazy...drink it no nstop....that way your urine will be diluted and if you havent used in 30 days if there is any thc left the home test may not be able to pick it up...another thing you could do if you have the money is go buy the same test kit..see if you pass it and then if you do you know your in the clear for your folks test..another word of advice I could give you...never give your first urine of the day,. its more concentrated and if there was anything left in you that most likely is the time it would pick it up...
Like I said I think your safe, especially if you have a faster metabolism, and I am assuming your still a teenager so you probably do....like I said, just drink a lot of water, not pop, not juice, water...and you should be fine...
good luck to you..and rememberdont use because your parents may throw a suprise test at you from here on out...its not worth it...
and if for some reason you fail the test, have your parents do some research on the internet about how long it stays in your system that way they know your telling them the truth if you drop dirty....
I think youll be okay though...but dont save the urine, the only way youll get away with that is if you know theyl be dropping you say that evening and you get the-+ sample that day...
good luck to you
let us know what happens
