For Christ's sake, you're on the bloody internet - look for sites with advice/hints/tips/ on how to pass a drugs test.
Here's a few things I found anyway:
* Drink lots of water -- at least two quarts a day several days before you wish all traces to be eliminated. Water is a natural cleanser and assists the body in the detoxification process.
* If you are giving a Urine Sample, use the third or later urine of the day and "catch" your sample in midstream -- not the first drops that come out.
* Excercise and dry sauna heat will help remove the THC for puposes of Detoxing. Do this in combination with heavy water intake.
* Stop exercising at least two days before your test because exercise increases the amount of THC in your urine. Since THC is fat-soluble and is stored in fat cells, exercise will help burn the fat cells thus releasing more THC into your urine sample.
* You should avoid all toxins and unnecessary medications for 48-72 hours before you are testing or need trace elimination to occure.
