QUICK ANSWER: 2-3 days (without smoking)

the CHEEK SWAB DRUG TEST monitors RECENT use, NOT HISTORICAL. the mouth replaces cheek cells every 48-72 hours. as long as you have not smoked within the 2-3 days before a test, you should be alright (with regular brushing, flossing and rinsing).

there has been a lot of controversy over how effective these tests are. they are VERY effective-... at catching people who smoke the day of the test. seems a little ridiculous that everyone is saying it takes a full month (or sometimes year) to get out of your CHEEK CELLS.

yes, THC remains in URINE for a month or so, but the cheek cells are replaced fast enough that 12+ hours for the infrequent smoker may even be enough (though why cut it that close).

there are also quicker (see: EXPENSIVE) alternatives, though they can get up into the $5

I 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

I've heard 2 weeks. Not sure if it is true or not. ----------------------------------------------------------- A friend of mine who is an insurance agent said up to 2 years (although a few cigarettes won't show up). His uncle had the swab done and claimed he was only a "celebratory smoker" and failed the swab.

theres no way to test for cigarettes just make sure you don't smell at the time of the "test"... you have to stop smoking weed for at least 2 weeks before the test otherwise that will show up.

Marijuana can take in upwards of 30-90 days to get out of your body. But as far as cigarettes go, I believe that the only test for that is in a juvinile detention area where they would test for nicotine in your system, because most people in juvy are under 18. Besides that, there isn't any test for cigarettes.
