What is the half life of THC metabolites in saliva?

The half-life of THC metabolites in saliva is generally estimated to be around 1 to 3 days. However, this can vary based on factors such as frequency of use, individual metabolism, and the sensitivity of the testing methods used. In chronic users, THC can be detectable in saliva for a longer duration compared to occasional users. Overall, saliva tests typically identify THC metabolites for a shorter period than urine tests.
