• Saliva can reveal very recent drug use up to 12-36 hours.

A saliva drug testing is also a relatively fail-safe way to ensure accurate results.

The method of sample collection—the test subject’s sample is taken while in a tester’s presence—it is extremely difficult and nearly impossible to tamper with, alter, or challenge the results of a test.
