My mother has been all over my case, and is going to give me a drug test. I haven't smoked in about two weeks, but i'm going to use someone else's pee just to make sure. If I hide the pee in the bathroom, how can I keep it warm? Or does that temperature even matter with an at-home drug test?
MJ can be detectable in your urine up to 30 days after your last smoke. Usually it disappears earlier, on the order of a few days, but keep in mind you are cutting it close, statistically.
you can buy test strips that can detect the smallest amounts of thc in your system. they have them at my local headshop.
