Nicotine is generally detectable in your blood for 1-3 days after you last vaped (or used a tobacco product :() It’s important to note that that is a rough estimate, and the length of time that nicotine stays in your system is dependent on many factors including age, how much or how often you vape or smoke, and your general health condition.
So as long as you haven’t vaped in 3 days you’ll pass the test with flying colors, right? Wrong. Sometimes nicotine tests are actually testing for a substance called cotinine, which is what nicotine transforms into when it metabolizes in your body. Cotinine can stay in your body for up to 10 days.
Time is the best method. If you know that you’re going to be taking a nicotine test in the near future, the best thing you can do is abstain from vaping until after the test.
But let’s be real: not everyone is willing or able to go without nicotine for that long. If you’re in a situation where you’ll be taking a nicotine test soon and you didn’t abstain for long enough, there are a few ways that could help you purge the nicotine from your system.
Make sure that you drink plenty of water, get tons of exercise, and eat a healthy diet. Take of your general health and you should see dramatically reduced levels of nicotine in your body. Of course it’s not going to be 100% effective, but if you’re right on the borderline then these methods might help you reduce your nicotine levels enough to pass a test.
