How long does marijuana stay in your saliva gland?

Marijuana can be detected in saliva for up to 24 to 72 hours after use, depending on factors such as the amount consumed, frequency of use, and individual metabolism. In occasional users, THC (the active compound in marijuana) typically clears from saliva faster than in regular users, who may have longer detection times. Testing methods and sensitivity can also influence how long marijuana remains detectable in saliva.
