Drug Testing - The Definitive Guide
DILUTION TECHNIQUE
It is almost impossible for most people to dilute successfully unless they have abstained for at least 2-3 days. The longer you have not used pot before your test, the easier it is to pass (obviously).
Creatinine
At few days prior to your test, you should raise your creatinine levels. Creatine metabolizes into creatinine within 24-48 hours after ingestion. Remember, the laboratories test creatinine levels in the urine to determine if you have diluted (drank too much fluid before a test). There is no “top end” to the normal levels of creatinine in your urine, but if your urine tests too low for creatinine you will receive a “diluted” result. Normal range is anywhere from about 110 – 200, and it is not uncommon for labs to see a lot of levels in the 20 – 30ng/dL; but as I said, there is no top end to the scale. Anything below 20ng/dL is considered “low” and can be an indication of a diluted specimen.
Aspirin
Anywhere from 4-6 hours prior to test time, you should take 3-4 aspirin. This is not to be confused with ibuprophen, advil or any other “non-aspirin” pain reliever. This has been reported to interfere with an immunoassay test and can help give a negative result. The labs have reported that they have overcome this “flaw” in the testing, but it really cannot do much damage and can help with the headache you are getting from all this nasty testing business in the first place., hours before the test take 4 aspirin (not Tylenol or Advil). This step may be repeated every 4-6 hours up until 4 hours before the test.
Fluid intake
Begin drinking a sports drink about 3 hours prior to test time. 16 ounces of Gatorade®, PowerAde® or any other brand of sports drink to start. Then, every 15 minutes, drink another 8 ounces and continue this for the next hour. Shortly after you finish drinking the sports drink you will begin to feel the urge to urinate. You should feel the need to pee every 20 minutes or so and your urine will be very clear (colorless). Drink about 4-6 ounces of the sports drink to replace what you have urinated each time you urinate.
Vitamins
When you begin to urinate every 20 minutes, you should take a b2 (riboflavin) or b complex vitamin. If you take a multivitamin each morning, the morning of your test, you might want to take 2 or 3 of them.
Make sure to void a couple of times at least, before you actually take the test. You want to flush any old urine, containing high amounts of THC, from your bladder before you go and give a specimen to be tested.
Practice helps. If you purchase a few home tests, (available cheap over the internet) try a dilution run at home a couple of days before your scheduled test. That way you can tell if the dilution method will actually work for you. If it doesn’t, you will need to look into substitution.
Remember, drinking loads of water, cranberry juice or tea in the days leading up to the test does nothing to “clean out” your system. All it does is waste toilet water and paper. You cannot “flush” THC from your system with excessive fluid intake. The entire purpose of the dilution method is to make the ratio of THC metabolites to urine fall below the cutoff level thereby obtaining a negative result. It doesn’t actually remove any more THC from your body, it just adds pee. Sort of like adding thinner to paint. It doesn’t remove the paint, just makes it less dense.
Quantity
You will, at the most, only need 60 milliliters of urine. That is approximately 2 ounces. The collector will probably ask for at least 4 ounces of urine. Be aware that the collector cannot reject your specimen for insufficient quantity if you have given what is needed. Just because more is asked for, does not mean that is the quantity that is required. Collectors always ask for more urine for a couple of reasons:
1. If we have a larger quantity, we don’t have to check the temperature quite as fast. The smaller quantity of urine, the faster the temp will fall after it is in the cup.
2. If we asked for only 2 ounces, inevitably most donors will only give 1-1/2 ounces or 1 ounce. That is not enough, you will not be allowed to leave the testing facility and you will be required to sit there and slowly drink water at a controlled pace until you can produce the required quantity.
If the collector asks for more, it is only to ensure the donor gives enough the first time.
Exercise
People who exercise regularly, people who are naturally thin or have very fast metabolisms are very lucky for more than the obvious reasons. THC is stored in the fatty tissue of the human body. The less fatty tissue a person has, the less stored THC that person has. People with faster metabolites tend to “turn over” the fat cells in the body at a much faster rate than their heavier, less active counterparts. For those of you who have a few weeks of notice before their tests, exercising can be a great way of reducing the levels of THC in the body.
Be sure to stop all or most activity about 5 days or so before test day. That will stop the body from burning fat cells and putting the THC into the urine. It helps to pig out on fatty foods during the few days before test time as well.
