No, they don't do a saliva test for marijuana, they do a urine test.
Saliva contains the enzyme amylase which breaks down starches in oats into simple sugars like glucose, which can then react with Benedict's solution to give a positive test result. The iodine test detects the presence of starch, which is in oats but not in saliva, explaining why the combination tested positive in both tests.
By not taking drugs. The saliva test can only go back a few days.
It usually takes about 1-2 days.
Saliva pH, in order to rule out major illnesses.
Saliva contains enzymes like amylase and proteins, which can interfere with the biuret test, typically used to detect proteins. The presence of these proteins in saliva can lead to a false positive result, as the biuret reagent turns purple in the presence of peptide bonds. Additionally, the enzymes may partially digest proteins, potentially altering the expected outcome of the test. Hence, when conducting a biuret test, saliva should be avoided to ensure accurate results.
