How long does nicotine stay in your system after quitting?

Hi all,

I'm trying to quit smoking as I have Cirrhosis the Liver and although I'm pretty healthy and not listed for a liver transplant I am part of U of Penn's transplant system and they require I quit (plus I really"want" to quit but I don't "believe" I can Sad ) PENN also "tests" for Nicotine so I'm really curious how long it stays in a person's system after quitting.

I did a search and couldn't find any answers to this question and hope someone here knows....How long does Nicotine stay in our system after we quit smoking?

I'm using the e-cig which all the Docs are saying is more effective than the Patch or Gum or Chantix. Hypnosis worked great for me years ago though...I just never got the chance to say goodbye to my last "sickarette" as I was late to the meeting.

I'm also using but I just don't believe I can do this. This habit is insane. It's breathing! Man, "breathing"...a little necessary, don't ya think?

Anyway, the best answer I've found while googling is from an expert on WebMD:

(this answer may be too long to fit in a "quote" box but I'll try it out)


"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.[b]


[b]Does anyone else know of any other answers?

Thanks and I'll check out more of the current discussions after my shoulder surgery next week (and liver mass follow-up ....Ugghh!)

HOPE and appreciation to you all! Glad this group is here!

The nicotine may leave the system, but the memory of smoking, where, when and why also stays with you a lot longer. Quitting is easy, it's the "Memory of the actions" which make it harder.
