Addictions

Have you ever wondered what a drug addiction does to your brain? There is much more to it than seen with the naked eye. An addiction is characterized the body's suspended manufacturing of a hormone or neurotransmitter that is being flooded in to the brain by a outside source.

When the natural supply is stopped along with quitting the drug, the brain is left without any dopamine.
