I have blue eyes, but my tendencies lean towards more natural substances, but I do like to get a drink on occasionally.

A new study from Geneticists at the University of Vermont have revealed links between eye color and alcohol dependency, suggesting it occurs more frequently among people with blue eyes and less frequently among those with dark brown eyes.

The study, which offers another piece of evidence that alcohol dependency has a genetic component, involved a sample of 1,263 individual genetic profiles. They were pulled from a database that only contains genetic profiles of people diagnosed with at least one psychiatric illness, which includes an addiction to, or dependence on, drugs or alcohol. For this study, the geneticists filtered the database for patients with alcohol addiction or dependence and European ancestry.

Repeated analyses of the sample led to the conclusion that European Americans with light eye colors, including blue and green and gray, had higher incidences of alcohol dependency than those with dark brown eyes, and that blue eyes were most strongly associated with the condition. The data showed that people with blue eyes were also more likely to have genes associated with alcohol dependence.
