First of all:
If you are currently using marijuana and know you have a test coming up, stop using immediately. The longer you abstain, the better your chances of passing a test will be.
One of the original methods of avoiding detection is to buy synthetic urine and substitute your urine with synthetic one. This works very well if you're not supervised. Another problem is that labs know what the temperature of a fresh urine sample should be and they also know that a sample should have blood particles in it of the blood type of the person being tested; so it is riskier to try and evade the urinalysis test by using a urine substitution. But if you don't have enough time for other way, this method is the only.
The other way is to clean your body from toxins and to pass the test in natural way.
First of all, you must eating a diet with low fat, low carbohydrate and low sodium. Eat as often as possible, and do not skip any meals, just eat 5-6 times a day. Eat as much as you want if you are following a low fat, low carbohydrate and low sodium diet. Drink a lot of water and use marijuana detox drinks so any stored marijuana metabolites will be flush from your system through urination. But remember: you should stop the dieting 48 hours prior to your drug test.
Exercise. As we know, THC stores in fat cells - exercises are burning fat and THC by products are released into the blood and urine that goes out while you cleansing your system. CRITICALLY IMPORTANT is to stop burning fat near test time (up to 48 hours before your drug test). On test day, it doesn't matter what's in your lipid tissue. What's in your blood and urine does matter.
Water: Drink at least recommended amount of fluid (preferably water) just prior to the test. Many people start drinking water several days before the test; which is useless. Water does not clean any THC metabolites out of your system because THC is not water soluble. Water only dilutes urine temporarily. And if you tried to drink a lot of water to dilute you sample, you will be under suspicion that you've diluted your sample, and your sample may be rejected on the basis of color alone. If a urine sample looks clear, the lab will suspect that it's watered down. They can't report it as positive, but they may reject the sample and inform your employer that you tried to beat the test. To avoid this, color your sample yellow by taking vitamin B. The most effective vitamins B-2 or B-12 you can find in detox drinks and detox pills that are selling in our store.
