How long does it take for traces of smoking not to be detected by a smoking test?

they say it takes 30 days to get out of your system this is true if your an every day smoker but if you smoke 2-3 times a week it should take 2-3 weeks since the last time you smoke if you still feel nervous goto your local GNC and ask for smothing to clean out your body of toxins but this is important don't ask for somthing to pass a drug test goldenseal root also gets it out of your sytem but its important it get all of that out of system before you take your test because it will show up as diluted.
