Nicotine causes a short-term increase in blood pressure, heart rate and blood flow from the heart. It can also cause arteries to narrow. The carbon monoxide reduces the amount of oxygen the blood can carry. When combined with nicotine’s effects, this creates an imbalance between cells’ increased demand for oxygen and the reduced amount of oxygen that the blood can supply. NITROGEN DIOXIDE Nitrogen dioxide (NO2) is a precursor to ozone (O3) formation. Current efforts to reduce ozone levels also target reductions in NO2 levels.
