Introduction

One of the most common questions among vapers and smokers alike is: how long does nicotine stay in your system? Whether you are considering quitting, preparing for a medical test, or simply curious about how your body processes nicotine, understanding the detection window is crucial.

In this comprehensive guide, we will break down everything you need to know about nicotine metabolism, detection times, and how different factors affect how long nicotine remains detectable in your body.

How Nicotine Is Metabolized in Your Body

When you inhale nicotine through vaping or smoking, it enters your bloodstream rapidly and travels to your brain within seconds. Your liver then metabolizes nicotine into cotinine, which is the primary compound tested in nicotine screenings.

Cotinine half-life: approximately 16-20 hours
Complete elimination varies based on individual factors

Regular users: 2-3 weeks
Heavy long-term users: up to 3 months

Hair Follicle Tests
