What is the key brain chemical involved in mediating the desire to consume tobacco or other drung?

Answer 1

The chemical most often implicated in addiction is actually a class of brain chemicals called neurotransmitters. Neurotransmitters are like little taxi cabs that carry messages to different parts of the brain. We often hear about the "feel good" effect of endorphines. Well, Endorphines are neurotransmitters.

The most studied neurotransmitter that plays a role in the function and action of addiction is Dopamine. It appears that dopamine receptors may be either damaged or missing in the brains of people who are addicted. Scientists can see that addicted people have fewer of these receptors through PET Scan imaging. Additionally, Serotonin and Norepinepherine have their own role in the addictive process as well.

Each of these neurotransmitters are intricately involved in the brain's reward system; the place where addiction grows and thrives.
