Nicotine`s Effects on the Body
... Nicotine’s Effects on the Body When a cigarette smoker inhales, about 25% of the nicotine in the smoke reaches the brain within six seconds-more than twice as fast as mainlining heroin. A pack-a-day smoker gets between 50,000 and 70,000 such nicotine joints per year. No other drug-taking habit comes ...

Haemodynamic response
In haemodynamics, the body must respond to physical activities, external temperature, and other factors by homeostatically adjusting its blood flow to deliver nutrients such as oxygen and glucose to stressed tissues and allow them to function. Haemodynamic response (HR) allows the rapid delivery of blood to active neuronal tissues. Since higher processes in the brain occur almost constantly, cerebral blood flow is essential for the maintenance of neurons, astrocytes, and other cells of the brain.
