Question

How far back can a mouth swab drug test detect cocaine use?

Answer 1

Mouth swabs are unreliable.  Where I work some pot was found in the mens room.  The company performed a mouth swab drug test on all the men.  They all failed.  They were taken to the hospital for futher testing and only 1 failed.

Answer 2

24 - 72 hours for a swab test.

7 days for a urine

30 days for a blood test.

2 years for a hair follicle test

Answer 3

First and foremost time to stop using cocaine. It is a ridiculous drug that is one of the hardest to get the 'coke monkey off your back". That being said check the link below. Normally it is a relatively simple formula. If the substance is water soluble it will clear your system usually within 72 hours, possibly up to 5 days if use is heavy. this would include cocaine. Pot smokers have it much harder as many factors come into play, frequency of use and potency of marijuana, can add up to 15 days to the clean out time. If you are trying to beat a drug test to get a job just remember that most companies that screen before hiring also have "random urinalysis" tests where you show up to work one day and are handed a plastic cup with a cap and must give a urine sample. Ergo... quit using drugs.
