Need to detect recent drug use with confidence? Oral fluid testing delivers fast, reliable insight into short-term substance exposure.

Because it captures substances present in the saliva shortly after use, oral fluid testing is especially effective for identifying recent consumption — a major advantage in post-accident or reasonable suspicion situations. It eliminates the delay associated with other methods and allows for on-the-spot collection without compromising accuracy.

Drug testing plays an essential role in ensuring that prescribed treatments are both safe and effective. From lab analysis to clinical trials, each stage is designed to uncover how a drug performs, what risks it may carry, and how it interacts within the body.

Delta-8 doesn't exit the body as quickly as many people think.

While most assume it clears in a few days, Delta-8 can remain detectable for weeks—or even months—depending on the testing method. Our bodies process Delta-8 through the liver’s P450 system, breaking it down into metabolites that drug tests look for. In fact, Delta-8 and Delta-9 produce nearly identical metabolites, making them hard to tell apart with standard testing. That’s why many labs fail to differentiate the two—but our testing methods are built to do exactly that.

When accuracy matters, choose testing that sees the full picture.
