For an at home test you can probably leave it there for a couple days. Its going to get stinkier the longer you leave it there. You wouldn't want to do this for a job drug test.
killerweed420 Reviewed by killerweed420 on . getting randomly tested, quick question alright so i've been clean for about 2 months now. im getting randomly tested by my parents and i'm wondering if i fill up a travel size shampoo bottle with my clean piss, how long will it last if i put it in the top part of the toilet under the lid thing? i know its not refrigerated but i think it would be cool water because of the constant flushing. any help would be great.
