Many employers use a saliva drug test as a post-accident drug test.Saliva or oral fluid based drug tests are becoming more prevalent because of their convenience and the fact that they can not be adulterated.Furthermore, on-site saliva / oral based drug tests in particular enable the implementation of random testing programs, proven to be the most effective type of drug screening.
Saliva / Oral fluid based tests are as accurate as urine. A saliva drug test is usually performed by employers, for either pre-employment, random, post-accident, reasonable suspicion, or return-to-duty testing.
Saliva / Oral fluid based drug testing most closely mimics results found with blood and is preferable for detecting on-the-job drug use or in post-accident applications in this case because the degree of intoxication can be approximated based on the amount of substance in the blood.Detection in saliva tests begins immediately upon use:* Marijuana and Hashish (THC): 1 hour after ingestion, for up to 14 hours* Cocaine (including crack): From time of ingestion for 48 to 72 hours* Opiates: From time of ingestion for 48 to 72 hours* Methamphetamine and Ecstasy (MDMA, “Crank,” “Ice”): From time of ingestion for 48 to 72 hours* BZD: From time of ingestion for 48 to 72 hours
The saliva drug test is becoming more popular as they are a less intrusive form of drug testing and are easiest to administer. The saliva drug test is able to detect more recent use than other drug testing procedures and are able to detect use within the past few days.
A saliva drug test is very product specific because there are no nationally accepted standards or cutoff concentrations for detection.
The saliva drug test does require lab processing to ensure that the test is accurate.
