Besides the method of testing the main difference between saliva testing and urine testing is the detection times.
- Urine drug testing can detect illicit drugs for a longer time frame. This is particularly useful for pre-employment drug and alcohol tests.
- Urine drug tests are the most cost effective and accurate form of testing to ensure that you have a safe work environment.
- Saliva drug tests can only detect illicit drugs if they have been recently consumed in particular cannabis. If the user consumed drugs within two to four hours (depending on drug usage) then a saliva test can be used.
- For recent drug use and impairment, a saliva drug test is the most useful for this purpose.
