Nicotine is generally
Nicotine is generally metabolized by your liver and then your kidneys. It takes these two vital organs anywhere from 72 hours to approximately 9 days to rid your system of this drug. During this time these essential parts of the body are working much harder than they are designed to do.
The effects of the nicotine are an entirely different story however. It really depends on how long you’ve smoked and how much nicotine has built up in your system for the physiological effects of nicotine to completely disappear. In general you can expect these effects to last for weeks or months, depending on how much and how long you’ve smoked.
The psychological and social addiction can last years. Some quitters I’ve talked to say that ten years later they still crave a cigarette, but that doesn’t mean you should give up. Managing these cravings, while it may be a lifelong journey, comes with tremendous health benefits. You’ll also not be setting a dangerous example for the young people in your life.
