This "way" is the mesolimbic - he is responsible for the vulnerability of people to drugs, alcohol and nicotine. Under Canadian neurologist, is the mesolimbic pathway that. The first perception of nicotine, such as making a particular receptor subtype, the brain is sensitive to the taste of cigarettes When the brain remembers the pleasant sensation for themselves, the relationship appears immediately.
