haha... i am also a fellow bud toker. Nothing like saying thanks to mother nature for blessing us with a wonderful herb. I just had a drug test today. Found out about it the day before. The night before that i smoked the peace pipe...Fuck!!! its a sketchy situation, and your right, drinking water doesnt cleanse your system. A couple of different things you can try are to eat some fatty foods like bacon or fried cheese the days going up to your test. The THC stays in the fat in your body and not in your urine. When your fatty tissue excretes the THC back into your system, that is when you piss it out. So eating fatty foods will cause another layer of fat to form making it harder for the THC to penetrate and move back into your system. This is not a guaranteed method though. There is no way of testing negative for certain. unless you use a wizzinator but those are expensive. You could also bring some one elses clean urine in but you will have to make sure it is warm enough. and if its anything like mine was they will make you empty your pockets. Now drinking water will dilute your sample possible allowing it to dive below the level you need to get to pass the test. It will also cause your urine to become very clear and labs will be able to tell that you have been trying to flush your system... sometimes thats as good as a positive reading. Now you can take b vitamins 3-4 hours before your test to add color back to your urine. Best ones are B-2 and B-12. Unfortunately i did not have these and used B-6. This did not work. You can also try to eat some peanut butter the day of the test. This will also add color to the sample. Now you can take 4 or 5 aspirin the day of the test... 5-6 hours before. This will also dilute the amount of THC that will show up possibly easing your sample under the level it needs to be under. I also read somewhere to eat fruits and vegetables the days up to the test.. i dont really know what effect this has, and i failed to try it so i dont know if it will work. Also try to eat light the day of the test. Finally. When you wake up on wednesday drink a big glass of water, urinate several times before going to see the doctor. You first piss of the day is the dirtiest. Also dont put the first or last parts of the piss into the cup these are also the dirtiest part. Instead piss into the toilet, stop, then resume in the cup and finish in the toilet. But remember you need to give them a sample that is large enough for what they tell you they need... Hope this could be of some help. Sorry its so long... good luck on your test...
