In brief: Nicotine effects

Phsyical nicotine withdrawl is complete usually 72 hrs or so from stopping.
But blood tests can still detect evidence of smoking 7 to 10 days later. Urine tests can find evidence 3 to 4 days after stopping.

In brief: Nicotine

Nicotine metabolizes quickly in the body.
Usually within 8 hours, also it depends on the amount someone smokes. The effects of smoking like if someone had copd- reversal of lung function may take 3- 6 months( provided there is not already a structural damage).
