How Long Can THC Be Detected In Saliva Test?
Hey I ve been looking up time frames on how long thc stays in your saliva. In lab saliva testing they also look for a sister drug which is remence from thc. I am wondering what is the longest time possible thc can be detected in your saliva. I didn t smoke for 24 hrs brushed my teeth alot and still failed a past saliva lab test.

Hello,
24 hrs is a short interval. 3 days is possibly long enough. HOWEVER, THC metabolites are quite sticky.
They lodge in fat. The one study really examining how long this stays detectable found sometimes weeks after the last smoke, the THC was detectable in urine but there isn't data on long term salivary testing in people who were very very heavy users for a long time. 3 to 5 days.
Hope I have answered your query. Let me know if I can assist you further.
Take care
