Hello, folks. My brother has been smoking for years and I am trying to make him quit. It won’t be an easy job. As far as I hear, it is a whole chemical process involved. I hear that dopamine, substance from brain plays an important role. I hope someone could tell me something more.

Hello. You have heard well. Dopamine does play an important role. Nicotine that is inhaled from tobacco gets into the bloodstream and reaches smoker’s brain in 7 to 10 seconds. Nicotine increases the levels of dopamine in the brain. Dopamine is a neurotransmitter. It is very important for feeling pleasure. This effect lasts only for several minutes, so people need to repeat that. That is why they take another cigarette and another… You will have to be persistent with your brother. Good luck!
