Ok. So a couple days ago I took a couple hits off a joint. Not something I usually do nor am I particularly fond of it; however I suffer from insomnia and I'd rather do that than take pills. So of course as my luck would go I got a call from one of the places I applied at for a job. Nothing's official yet and I'm not even sure they do but if they do a UA it won't be until a couple weeks from now. I was wondering if drinking A lot of water really does flush the trace of marajana out of your system quicker? I mean its not something that I make a habit of its just that I really need this job and obviously if it comes out positive I doubt they'll let me get the job. So...

It doesn't flush it out any faster. It dilutes the sample making it harder to detect.

However, what many don't consider is that all diluting a sample really does is affect the measurement of quantity of a substance. A certain measure is considered a "hot" result. Meaning say 25 parts per million of substance X is considered a failed test.

If you had a few hits, are not a habitual user and don't have the test for a few weeks, most likely you will be fine. If it is a concern of yours, consider NOT taking illegal drugs ever, no matter what the reason. A law is a law regardless of your reason for breaking it. The judge (or employer) could not care less that you can't sleep.
