How long does thc stay in your saliva?

THC: All of the cannabinoids have a very long half-life in the body. In the case of thc in saliva, i would expect that it would be detectable for up to 30 days or longer since the last dose.

Dr Pappas and another doctor agreed

In “Pharmacokinetics: Of cannabinoids” by mcgilveray ij it is stated “saliva testing is a newer, less proven technology. The sensitivity of saliva tests is not well established in the case of marijuana. In theory, they are supposed to detect recent use, but this may range from several hours to over a day. They are supposed to detect secretions from inside the oral tissues that cannot be washed out with mouthwash.”.

THC in saliva: Thc is generally detectable in saliva for 1-10 days. However, urine testing is the more common approach -- and length of detectability depends on frequency of use.

Dr Fowler agreed
