Pros: Saliva (Oral) drug test kits are very donor friendly, non-invasive and easy to collect the specimen. There is no need for a bathroom to administer the tests. Saliva drug testing is great at detecting very recent drug use. Also these drug tests are harder to adulterate than the urine drug tests since the sample can be obtained under direct supervision. Results can be read in minutes and there is no need for a lab. Depending on the test, up to 8 (5 or 6 at a time) different drugs could be detected. This method is the best method for determining current use and impairment.
Cons: The main disadvantage of saliva based drug test kits is their detection window. Depending on the variation of the rate of saliva production of the person or the type/density of the drug used ranges from a few hours to at most 2-3 days. Also smoked drugs might cause contamination of saliva and inconclusive results. If saliva test suits your requirement and want to know more information about it, check it out here
