how does it work


Question by  Mike1346 (35)

How do swab test drugs work?

How long after doing the drug does it stay in your saliva?


Answer by  AlexW (407)

The swabs in the test are used to collect saliva and body cells. Once on the swab, they can be brought in contact with a testing agent. Some drugs stay in your system and saliva much longer than others.
