What effect does smoking a cigarette have on the brain?

Answer 1

The main affect is the carbon monoxide in cigarette smoke binds to the hemoglobin molecules in your red blood cells 40x stronger than oxygen. So, in effect, when you smoke, it reduces the amount of oxygen available to the brain. This creates the euphoric 'high' that cigarette smokers experience. In addition: The chemical nicotine has been proven to be one of the most addictive substances known, even stronger than heroin addiction.
