What is a saliva drug test?
A saliva drug test is a method of determining whether an individual has engaged in the use or ingestion of specific drugs. Basic drug tests commonly screen for five categories of substances, including cannabinoids, opiates, cocaine, amphetamines, and phencyclidine, while expanded tests can include these and many more. During a saliva drug test, the subject is generally prohibited from placing any items in the mouth for a specified period of time. Saliva is then collected and analyzed for the presence of numerous substances. Oral drug tests can usually detect a substance from the point of ingestion through a period of hours or days.
