How long does nicotine stay in my blood?

I've always heard it is three days but to give you an accurate answer I looked it up on a few medical sites. Glad you asked the question and I looked because it's nice to know the old standard I always heard is incorrect. ;-)
Depending on your system it can still be in the blood for up to twenty days and in your urine for about four days. It also depends on the amount and frequency of nicotine you use that your liver needs to process out of your body via the kidneys.
When I quit smoking, at 10 days I didn't have the super urge to smoke. Good luck.
From the American Heart Association website:
How long does nicotine stay in the body?
From 85-90 percent of nicotine in the blood is metabolized by the liver and excreted from the kidney rapidly. The estimated half-life for nicotine in the blood is two hours.
