Sure there are other drug tests on the market, but I can't find one saliva test, and I have been looking, that has the sensitivity and the simplicity of use that Oraline IV does.
Urine tests are abundant, but what the world needs is a simple early detection method so as users can be referred on to more sophisticated, more intrusive tests (urine) and programs.

If you can find one as good as Oraline IV please feel free to post it.
