Alcoholism or alcohol-use-disorder, is considered to be a hereditary trait by many. Some scientific studies suggest that there is a gene for alcoholism. Some scientists and psychologists are convinced that addictive behaviors are traced back to early childhood trauma, neglect and the effect that both have on our developing brain. Others suggest that addiction is based primarily in the use of substances designed to addict. If you drink often enough you will become addicted. No matter what your family history.
