nicotine effects on brain
Memory-like effects in brain reward pathway could contribute to drug addiction. The effects of nicotine upon brain regions involved in addiction mirror those of cocaine, according to new neuroscience research. A single 15-minute exposure to nicotine caused a long-term increase in the excitability of neurons involved in reward, according to a study published in The Journal of Neuroscience.
When you smoke you induce nicotine into your blood stream. The nicotine travels via the blood stream to different parts of the body including the brain, heart, liver, kidney and pancreas. When it reaches the pancreas it has a effect of blocking the production of insulin.
