how long does it take for marijuana to clear out of your saliva
How long does weed stay in your saliva? Now before you get excited, hereâs the disadvantage of saliva tests. They are very good at detecting very recent marijuana use. If less than 24 hours has elapsed between your last joint and the time of the test, you will likely test positive. And more sensitive laboratory tests can easily detect it up to 72 hours after intake. Chronic heavy users facing a sensitive saliva test can be detected for up to a week in general. THC doesnât remain in your saliva for very long and itâs not easy to detect. But, to ensure that you pass your test, itâs best to stop using at least three days beforehand. Sometimes this is not possible as employers will spring a test on you suddenly.
