How Long After Marijuana Consumption Does It Show On Saliva Test?

How long does marijuana shop up in the saliva test? Was about a 12-14 hour window from when I last smoked and when I took the test. I made sure not to press swab against my cheek. Ate dinner afterwards and brushed my teeth and mouthwashed as usual. What should I expect?

Hi,
Thanks for writing in.

Whatever the test used, THC (the active ingredient in cannabis) can never be detected more than 4 to 6 hours in saliva. Most likely you are going to have a negative test of marijuana in saliva. The cut off level is usually 25 ng/ml. Accurate information is given by the manufacturer of the test kit.
