A saliva drug test is a potent tool that can help you discover whether someone is currently high on drugs, or if not currently high, whether they have used drugs quite recently. In this way, you can think of it as a disposable breathalyzer for illegal drugs. Amphetamines, methamphetamines, and cocaine all appear in your saliva 5-10 minutes after use, and it takes 72 hours, 72 hours, and 24 hours respectively for the drugs to disappear from your saliva. A saliva drug test is the only home drug test that gives you the opportunity to tell whether someone is high.
