The answer to this question depends a little bit on the source of the nicotine. For instance, nicotine patches and gums contain a specific dose of nicotine that is designed to clear from the body after a short period of time. Nicotine absorbed by the body through smoking, chewing and other tobacco use can linger for a longer period of time. Each person's unique metabolism also plays a role in how quickly the body gets rid of nicotine.

In terms of testing, nicotine may be detectable up to 30 days after a person last used it. Some types of nicotine tests are more sensitive than others. For example, a blood test is generally considered more sensitive than a urine test, which means a person who passes a urine nicotine test might not pass a blood test. Other types of nicotine tests include saliva and hair testing.

In terms of smoking cessation, nicotine withdrawal symptoms usually peak between 12 and 24 hours after the last cigarette. As the nicotine slowly leaves your system, these symptoms will decrease.

If you have concerns about nicotine withdrawal or smoking cessation, talk to your healthcare provider.
