Saliva drug testing is becoming increasingly popular for a few reasons. First, it is fairly inexpensive; second, it is easy to administer by someone with little or no training, and third it is less intrusive than a urine drug test, hair sample drug test or a blood drug test. Saliva drug testing does not measure drug metabolites as with most drug testing, but measures the amount of the actual drug in your system. This makes it easier to pass a saliva drug test as opposed to a urine drug test. Most drugs will be out of your system in 2 or 3 days. Some oil soluble substances like THC in marijuana, may be present and show up on a drug test for up to 90+ days.
The best thing you can do to prepare is to avoid all toxic substances as the drug test is approaching, drink lots of water, workout intensely enough to sweat (perspiring eliminates a lot of toxins) and eat a healthy diet. If you are unsure whether or not you will pass, the best thing to do is test yourself at home first. If that test shows a positive result, use the Ultra Klean mouthwash which comes with a double your money back manufacturer's guarantee. It works instantly and is effective for 30 minutes.
