how long does it take for cocaine to get out of your system for a swab test
How long does it take for THC to get out your system with a saliva swab test? approx detection period for saliva testing /thc - 1-3 days to max 7-10 days .Main thing ...this type of test don't have nationally accepted standards or cutoff concentrations â¦ so result and time for detection will dependent on the test. have a friend that took a swab test for THC .And it tested positive 5 weeks after they stopped smoking...I was told by a counselor that it depends on how often you smoke as to how long it will take to be undetected..usually 4 to 6 weeks.
