A member asked:
How is nicotine expelled from the body? i am a light smoker, i smoke 2-3 cigarettes in a 24 hour period.
A doctor has provided 1 answer
If you smoke that: Little, there is no reason you can't stop. Even 2-3 cigarettes a day causes a measurable increase in problems like coronary heart disease, stroke, bronchitis and cancer. Nicotine is metabolized to cotinine which is excreted in urine, but while nicotine is present, it causes vasoconstriction, clamping down and depriving the vessels of oxygen, increasing arteriosclerosis in heart, brain, elsewhere.
