What’s In Tobacco
The nicotine in tobacco smoke travels quickly to the brain, where it acts as a stimulant and increases heart rate and breathing.
Tobacco smoke also reduces the level of oxygen in the bloodstream, causing a drop in skin temperature.
Research has shown that smoking raises levels of dopamine, a chemical in the brain, increasing feelings of pleasure and reinforcing the desire to continue to smoke.
