Absorption of Smoking.
Tar & carcinogenic compounds affect the oral and resp. tissue prior to absorption, once nicotine is in the lungs it passes quickly to circulatory system.
-
Distribution of smoking:
once absorbed, nicotine, tar and carcinogens are processed in the liver, sent to brain, and excreted in the kidney. Once nicotine is in the liver, converts to cotinin. Once in the brain, triggers release of dopamine, noreip, endorphins, and serotonin.
