The Genetics of Alcoholism Why can some people have a glass of wine or beer with their meal without feeling compelled to drink more, whereas others can’t seem to stop drinking? Can some people “hold” their liquor better than others? Does alcoholism tend to run in families? Does genetics hold the key to developing medications to treat alcoholism and its effects on the body? Researchers have been trying to find answers to questions such as these for several decades, seeking to identify the factors that influence a person’s risk of becoming alcohol dependent. Research, to date, indicates that both your genetic makeup (i.e., the information stored in the DNA that you inherited from your parents) and your environment (i.e., how you live) influence your risk for alcohol abuse and alcoholism. Your genes certainly play an important role, influencing how your body responds to alcohol, how sensitive you are to its effects, and how likely you are to have a problem with alcohol. However, environmental factors—such as being surrounded by people who are heavy drinkers and who encourage you to drink—also can raise your risk for drinking too much.
