Oral Fluid Test (Saliva Drug
Screening) is the least invasive test available.Saliva is collected from the inside of the mouth and tested for the
presence of numerous drugs like marijuana, cocaine, opiates such as heroin and
prescription medications, amphetamines, and methamphetamines. These tests can detect drug usage immediately after use, and up to one to two days later. Oral
fluid drug testing cannot be adulterated or substituted. Oral Fluid Testing provides an increased discretion for clients.
