My god what a fucking beautiful woman ! <| sep |> A quick googling implies that nicotine itself is cleared out within 24 hours , maybe as little as 12 , and cotinine can stick around for 2 to 6 days . As for detection , seems that saliva tests can detect cotinine up to 4 days since last exposuremaybe more depending on intake , but 6 mg I ' d wager closer to 4 days . During said googling I found theories on how to clear it out of your system faster . Methods included drinking more water or cranberry juicepure , not the cranwhatever stuff which is mostly apple juice , basically you want to be pissing a lot , exercising , eating healthier , and staying off nic for up to a week before the test <| sep |> Y ' all are next on the hit list .
