Depends, have you smoked weed recently? If so, then yes.
Thc can be detected in the saliva for 5 to 10 days depending if you are a heavy user.
Alcohol for a swab test go back
It sits in your mouth inbetween your teeth and cheek and soaks up the saliva. If there is THC in your cheek cells, it will be in your saliva. (Your cheek cells are replaced with fresh ones quickly. Don't consume THC for 3-4 days, and you will pass a mouth swab.)
i doubt that it can be detected but anythings possible and they also usually take a urine sample when they do a oral swab test and it can definitely be found there
Alcohol can be detected in your system from a cotton swab test for two days. A cotton swab test is also known as a saliva test, and results can vary depending on how much alcohol was consumed.
yes
Anything that can destroy cells. The cheek swab collects cells, which are then used to extract DNA for testing. To my knowledge, there is nothing short of cellular destruction that can impede the collecting of a sample for a DNA test, since the test is actually conducted on the DNA extracted from INSIDE the cell, not just the swab.
Benzodiazepines can be detected up to a week after use.
The only way suboxone can be tested for is through its on specialized test that is very rare and expensive. You will be fine on the check swab.
Well it would collect an even better sample.
No. The test is done on the cheek cells because they have DNA in their nucleus. The swab can be taken from any part of the mouth or even a "punch" from the skin.
