How long does nicotine stay in your system?

Question

I had 3 cigarettes yesterday and one cigarette today. This is the first time I have smoked in months. I think I might have to take a drug test within the next couple of days for this program I'm in. Will I pass the test?

Answer 1

Nicotene will leave your body within two weeks.  I did hear that drinking grapefruit juice helps your body get rid of it quicker.  Are you in rehab?  I think cigarettes aren't allowed in rehab, in which case you might be in trouble.

Answer 2

Nicotine and cotinine are rapidly eliminated by the kidney; the window of detection for cotinine in urine at a cutoff level of 200 ng/mL is expected to be up to 2-3 days after nicotine use
