Understanding Saliva Tests for Cannabis
Saliva tests are often used due to their non-invasive nature and ability to detect recent use of cannabis. They function by detecting Delta-9-THC, the active component in cannabis.
It’s important to note that these tests are generally sensitive and may indicate a positive result even in case of passive exposure to cannabis smoke.
Medical cannabis users and people using CBD products should be aware that depending on the THC content of their medication, they could also test positive in a saliva test.
