Binge drinking is a particular concern, defined as consuming five or more drinks for males or four or more for females within about two hours, according to the NIH. But if they can confirm the link, the big challenge will be working out whether it’s caused by genetics, environmental factors, or a mix of the two. One sign of AUD is engaging in certain behaviors during or after drinking that may have harmful effects. For example, a person may engage in activities that risk unwanted or harmful consequences while drinking alcohol. Many people with alcohol use disorder hesitate to get treatment because they don’t recognize that they have a problem. An intervention from loved ones can help some people recognize and accept that they need professional help.
- A notable gap in population-based studies has been identified, highlighting the need for more targeted research in this area.

- Whether you have blue eyes, green eyes, brown eyes, or any eye color in between, getting comprehensive treatment for alcohol addiction is the best way to start on the path to recovery.
Do People with Blue Eyes Have the Highest Alcohol Tolerance?
We measured blood alcohol concentration with a breathanalyzer among 61 customers from various occupational backgrounds, and calculated the association between eye color and BAC. Results showed that among males and females, irrespective of age, participants with blue eyes had a higher BAC than the others … This ecological result suggests that iris pigmentation represents a biological marker for underlying factors involved in higher alcohol consumption. The study followed 1,263 European Americans and controlled for factors such as age, sex, and genetics. Researchers concluded that among their sample population, those with light eyes (defined as blue, green, and grey) were more likely to exhibit signs of alcohol dependency than their dark-eyed counterparts.
Drinking more than intended
Moreover, among the light-eyed, subjects with blue eyes had the highest rate of alcohol dependency. Neither Sulovari or lead author Dawei Li, professor of microbiology and molecular genetics at the University of Vermont, said they think there will be one genetic silver bullet to stop alcoholism. Such research could ultimately lead to more effective strategies for the prevention and treatment of alcoholism and other substance use disorders. However, the complexity of genetic research, including factors such as assortative mating and shared environment effects, often challenges the validity of such findings. For instance, the heritability of alcohol use disorders, as shown in meta-analyses of twin and adoption studies, may be influenced by these factors. Despite these challenges, twin studies continue to provide valuable insights into the genetic underpinnings of alcoholism and other addiction disorders.

The “gene for sickle cell disease” is actually the adult beta hemoglobin gene, which we all have. Sickle cell disease patients inherited a particular form, or “allele” of the beta hemoglobin gene that causes their red blood cells to sickle under low oxygen tension. Upon first encountering a new patient, a good physician self-reported negative outcomes of psilocybin users notes physical features that suggest increased risk of pathology. A patient with clubbed fingernails or toenails should be evaluated for pulmonary insufficiency. That’s what Kyle Parker discovered when he left his hometown of Chicago in 2013 to attend Grinnell College in Grinnell, Iowa, population 9,031.
Personalized medicine, also known as precision medicine, is an emerging field that tailors medical treatment to the individual characteristics of each patient. The potential of personalized medicine is particularly evident in the field of genomics, where DNA analysis can inform the diagnosis and treatment of diseases. An intriguing aspect of this is the consideration of genetic factors such as eye color. Statistically, individuals with blue eyes constitute approximately 8% of the global population.
While 24% of Grinnell College’s students identify themselves as people of color, fewer than 10% of residents of the city of Grinnell would say the same of themselves.

Scientists controlled for other variables that could influence the result, such as age, sex and genetic ancestry. Another study indicated that European Americans with blue eyes had a higher incidence of alcohol dependence. This research posits that the genetic components determining eye color may align with those related to excessive alcohol use, suggesting a potential correlation meth withdrawal symptoms timeline & detox treatment that warrants further investigation. But for the majority of illnesses, our genes only give us a predisposition towards diseases, affected by environmental factors. And for a disease like alcoholism, there are a huge number of non-genetic factors that can influence how and why people drink, such as social or cultural attitudes, income level, upbringing, and stress.
From that database, the study’s authors filtered out 1,263 alcohol-dependent people and retested three times after noticing the connection to eye colour. Call us today to speak with a Recovery Advocate for free about your treatment options. Alcohol use disorder (AUD) benzodiazepine withdrawal is a medical condition characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. Participation in support groups may help people develop strategies to deal with the urge to drink alcohol.
Human eye color is a pretty strange thing – it’s an inherited trait influenced by more than one gene. These genes cause small changes in the genes themselves and in neighboring genes, and we actually don’t know all the genes responsible for eye color. With ranges from light blue to dark brown, you can tell a lot about a person just by looking at his iris color, perhaps even if he’s more likely to become an alcoholic. As it turns out, the genetic components that determine eye color line up along genes related to excessive alcohol use, the study authors explained. Li came to the University of Vermont in 2012 and has studied psychiatric genetics for a decade.
Rose Foods also makes a number of bagel sandwiches, including the Classic Nova with Nova lox and the Classic Whitefish. Trump has appeared to be sleeping in court on numerous other occasions over the course of the trial, which entered its 10th day Thursday. On Tuesday, NBC News reported that Trump’s “eyes were closed for extended periods and his head at times jerked in a way consistent with sleeping.” His campaign previously lashed out after multiple reporters in the courtroom, including The New York Times’ Maggie Haberman, reported on the first day of jury selection that Trump seemed to doze off a few times.
Therefore, the complexity of the blue eyes-alcoholism connection is not only a matter of genetics but is also intricately tied to environmental contexts, underscoring the importance of considering a holistic approach to understanding AUD. The scientific community maintains a cautious stance, considering these findings as preliminary. Genetic, psychological, social and environmental factors can impact how drinking alcohol affects your body and behavior.
For example, if a specific genetic overlap between blue eyes and alcoholism were confirmed, individuals with this trait could benefit from targeted education and prevention programs. Strategies could also involve modifications to treatment approaches to accommodate genetic vulnerabilities, similar to mental health services adjusting their support structures to prevent further harm or trauma. The Vermont study is one among many that attempts to link genetic factors to alcohol misuse. Still, without further studies to confirm and clarify these initial results, the scientific community remains cautious about drawing definitive conclusions. Moreover, the study participants all had at least one mental health disorder, which complicates the interpretation of the data as it suggests that the association with alcoholism could be confounded by other psychiatric conditions.
Furthermore, while some studies have found statistical associations between blue eyes and higher rates of alcohol dependence, causation cannot be inferred from correlation alone. The prevalence of blue eyes in certain populations may coincide with alcoholism rates for reasons unrelated to genetics, potentially leading to erroneous conclusions. The scientific consensus emphasizes the need for more rigorous research, which would include larger sample sizes and diverse populations, to explore the nuances of this potential connection more deeply. Interventions could include early detection and more nuanced risk assessments.
Critics of the eye color-alcoholism connection point out various limitations and challenges inherent in such research. Factors such as cultural background, environmental influences, and socioeconomic status can play substantial roles in alcohol dependency and may coincide with genetic factors like eye color. These variables must be meticulously controlled to assert a causal relationship.
Alcohol use disorder (AUD) is a complex condition influenced by a combination of genetic, environmental, and social factors. While no single gene can be pinpointed as the sole cause of AUD, research indicates a strong genetic component to the disorder. The heritability of AUD is estimated to be around 40%, suggesting that genetics plays a significant role in the risk of developing this condition. People with blue eyes might have a greater chance of becoming alcoholics, according to a unique new study by genetic researchers at the University of Vermont. Most Americans are taught that eye color is a single-gene trait – that a brown-eye gene variant is dominant over the blue-eye variant. The OCA2 gene on human chromosome 15 has a major impact on eye color by producing a protein that controls melanin formation and processing.1 The more OCA2 activity in the iris melanocytes, the darker the eye color.
