What is Drugs of Abuse Saliva Testing? (Background Information)
- Ethanol (drinking alcohol) is the most commonly abused legal substance. Additionally, performance-enhancing drugs, such as steroids and erythropoietin, can be tested
- To test for the presence of the above compounds, an initial screen is first performed. The initial screen detects the presence of a drug or its byproducts
- However, the initial screen may detect compounds that are similar to illegal drugs and their byproducts. To differentiate between this and a legitimate drug abuse, a secondary test is performed, which is more sensitive
- The Drugs of Abuse Saliva Testing is used to detect the presence of illegal drugs or their byproducts in saliva. The test is used to determine if an individual has taken illegal drugs. It is also used to diagnose a drug overdose
The National Institute for Drug Abuse (NIDA) has put together a list of the most commonly abused drugs. These include:
- Amphetamines – stimulants (e.g. methamphetamine and Adderall®)
- Barbiturates – depressants (e.g. phenobarbital)
- Benzodiazepines – depressants (e.g. diazepam or Valium®)
- Cannabinoids – hallucinogens (e.g. marijuana)
- Opiates – depressants (e.g. codeine, morphine)
- Phencyclidine (PCP)
- Tricyclic antidepressants (TCAs)

What is the Significance of the Drugs of Abuse Saliva Testing Result?
- Positive Drugs of Abuse Saliva Test indicate that an individual’s saliva contains significant levels of a drug of abuse.
The laboratory test results are NOT to be interpreted as results of a "stand-alone" test. The test results have to be interpreted after correlating with suitable clinical findings and additional supplemental tests/information. Your healthcare providers will explain the meaning of your tests results, based on the overall clinical scenario.
Additional and Relevant Useful Information:
- Some drugs, such as methylenedioxy-methamphetamine (MDMA), are difficult to test because adequate procedures are not available, unlike for many other drugs
- Furthermore, drugs like gamma-hydroxybutyrate (GHB) are quickly cleared from the body. Thus, by the time a test is performed, significant levels may not remain in the body
Certain medications that you may be currently taking may influence the outcome of the test. Hence, it is important to inform your healthcare provider, the complete list of medications (including any herbal supplements) you are currently taking. This will help the healthcare provider interpret your test results more accurately and avoid unnecessary chances of a misdiagnosis.
