There is no right or wrong answer to this question. Both tests have pros and cons, so some people may argue that it’s not easy to respond to this question because there are a few things to consider.
Since drug tests have been available for employee drug screening, most employers, organizations and companies have chosen “urine drug testing” as the preferred drug testing method because there are multiple studies showing its benefits and effectiveness, such as “sensitivity and specificity”.
The advantages and disadvantages of urine testing are obvious and generally understood by most people who are involved with drug testing. Nonetheless, there are many people, organizations and employers who prefer using the “saliva or oral fluid” testing.

Drug detection time:
- Urine drug test: Days or weeks
- Saliva drug test: As short as one hour
Ease of collection:
