Biochemical Aspects of Addiction

When a person drinks or uses drugs over a period of time, the body becomes unable to completely eliminate them all. Drugs and alcohol are broken down in the liver. These metabolites, (the substances the body converts the drugs or alcohol into) although removed rapidly from the blood stream, become trapped in the fatty tissues. There are various types of tissues that are high in fat content, the one thing in common - and the problem that needs to be addressed - is that these drug residues remain for years. Tissues in our bodies that are high in fats are turned over very slowly. When they are turned over, the stored drug metabolites are released into the blood stream and reactivate the same brain centers as if theperson actually took the drug. The former addict now experiences a drug restimulation (or "flashbacks") and drug craving. This is common in the months after an addict quits and can continue to occur for years, even decades.
