How long does nicotine stay in your system. I haven’t smoked in about a month. I am suppose to get blood test for life insurance. Wife dosen’t think I smoke. HELP!!!

I hear that it stays in your system for two weeks. At least that is how long your body craves it when you quit smoking. I don’t think it would be any longer than that.

Nicotine is short acting and is long since out of your system. The half-life is only about an hour.

The reason that users crave nicotine for
a couple of weeks after cessation has
nothing to do with nicotine remaining in the system that long: it doesn’t.
