How Saliva Tests Work
Saliva tests detect THC, the psychoactive compound in cannabis, through a process called salivaysis. They are typically administered at the point of care and provide results within minutes.
How Long Do Cannabis Metabolites Stay in Saliva?
Duration of Detection
Saliva tests can detect THC for up to 24 to 72 hours after a single use. However, the duration of detection can vary based on several factors, including the amount of cannabis consumed and an individual's metabolism.
Implications for Testing
Understanding the detection window of saliva tests is crucial for employers, parents, and individuals undergoing testing. A single use of cannabis could result in a positive test for up to three days.
