So exactly what does happen when you smoke?

Every puff on your cigarette delivers, via the lungs to the brain a small dose of nicotine that actually acts more rapidly than a dose of heroin an addict may inject into his veins.

Because nicotine is a quick-acting drug the levels in the bloodstream drop quickly to about half within a half an hour and a quarter within an hour of finishing a cigarette.

As soon as a smoker extinguishes a cigarette, the nicotine rapidly begins to leave the bloodstream and the smoker begins to suffer withdrawal symptoms - that restless feeling that says "I want a cigarette".
