Not sure but you can beat a saliva test by gargling with hydrogen peroxide before u take the test.I know because i got my job by doing it.
NO... this is not true! The furthest back a drug test can go is about 6 moths if they use a sample of your hair. Urine drug test can only go back as far as a month.
By not taking drugs. The saliva test can only go back a few days.
Alcohol for a swab test go back
If you are talking about a drug test any illegal substance can normally be detected for 30 days in blood, saliva, and urine. It can be detected in hair samples for up to 6 months after last use.

the one that i work at gave a saliva one on the spot but someone else that was hired had to go take a urine test because they ran out of the saliva ones
test are standardized they look back up to 3 months (1.5" of hair ) only court orders go back farther
Hair drug tests can go back seven years. It is not against the law to ask how far back they test before you submit to the test
