Saliva blood tests operate by checking for tiny residual amounts of drugs within the saliva. The person being tested wets the test strip with their saliva, and the test shows results using colored bands. Saliva tests check for the presence of opiates, marijuana, cocaine, methamphetamine, and phencyclidine drugs. Any trace of one of these drugs will cause the band corresponding to that drug to change color. A drug-free result would show no color at all.
Pass any Saliva Drug test, Oral Fluid Drug test or Swab Drug test for THC, COC, OPI, MET or BZD! Saliva testing is generally a short-term procedure. It is commonly used for detecting the presence of Nicotine, alcohol, marijuana, meth and cocaine in the chemicals in your mouth.
