Alcohol consumption has been a contentious issue in research for years, with studies suggesting that there is no safe amount of alcohol consumption. The World Health Organization (WHO) has published a statement in The Lancet Public Health affirming that alcohol consumption carries health risks, and there is no safe amount that does not affect health. Alcohol is a toxic, psychoactive, and dependence-producing substance, classified as a Group 1 carcinogen, alongside asbestos, radiation, and tobacco. While some studies suggest potential protective effects of light to moderate drinking on cardiovascular diseases and type 2 diabetes, these benefits do not outweigh the cancer risk associated with alcohol consumption. The WHO advises that the more one drinks, the more harmful it becomes, and the less one drinks, the safer it is. This is further supported by the U.S. Dietary Guidelines, which recommend limiting alcohol intake to one drink or less for women and two drinks or less for men on any single day, rather than on average.

Alcohol is a toxic, psychoactive, and dependence-producing substance
Alcohol has been consumed by humans for its psychoactive effects for thousands of years, and it is currently the second most consumed psychoactive drug globally, after caffeine. While alcohol consumption is generally socially acceptable and legal in most countries, it is associated with significant health risks and negative consequences. Alcohol use is linked to morbidity and mortality, with approximately 2.6 million deaths attributed to alcohol consumption in 2019.
The toxic effects of alcohol are mediated by its carcinogenic byproduct, acetaldehyde. Even small doses of ethanol can have stimulant-like effects, leading to euphoria, relaxation, and decreased inhibition. However, excessive alcohol use can result in adverse effects, including alcoholism, dependence, and withdrawal symptoms. Alcohol use can also affect the metabolism of certain medications, such as warfarin, increasing the risk of bleeding.
The World Health Organization (WHO) advises that there is no safe level of alcohol consumption. Any amount of alcohol consumption carries some level of risk. However, the level of risk depends on various factors, including the amount consumed, frequency of drinking, individual health status, age, sex, and personal characteristics. While some groups may be more susceptible to the negative effects of alcohol, adopting lower-risk drinking patterns can help reduce the likelihood of negative health and social consequences.
To minimize risks associated with alcohol consumption, it is recommended to limit intake to one drink or less for women and two drinks or less for men per day. However, it is important to note that even low levels of alcohol consumption have been linked to increased risks for hypertension, arrhythmias, and cancers of the mouth, throat, and breast. Therefore, the general guideline is that for those who choose to drink, the less alcohol consumed, the better.

There is no safe amount of alcohol that does not affect health
Alcohol is a toxic, psychoactive, and dependence-producing substance. It has been classified as a Group 1 carcinogen—the highest-risk group, which also includes asbestos, radiation, and tobacco. As such, there is no safe amount of alcohol that does not affect health.
The World Health Organization (WHO) has published a statement in The Lancet Public Health, confirming that any amount of alcohol consumption affects health. Dr Carina Ferreira-Borges, acting Unit Lead for Noncommunicable Disease Management and Regional Advisor for Alcohol and Illicit Drugs in the WHO Regional Office for Europe, explains that "the risk to the drinker's health starts from the first drop of any alcoholic beverage". This is because ethanol (alcohol) causes cancer through biological mechanisms as the compound breaks down in the body. Any beverage containing alcohol, regardless of its price and quality, poses a risk of developing cancer.
The U.S. Dietary Guidelines recommend that healthy adults who choose to drink alcohol should limit their intake to one drink or less per day for women and two drinks or less per day for men. However, it is important to note that even low levels of alcohol consumption have been associated with greater risks for hypertension, arrythmias, and cancers of the mouth, throat, and female breast.
While moderate drinking may reduce the risk of negative health effects compared to excessive drinking, it may still increase the risk of death and other alcohol-related harms compared to not drinking at all. For example, drinking about two drinks per day does not lower the risk of death compared to not drinking. In fact, it may increase the overall risks of death and chronic disease, including cancer and heart disease.
Additionally, the potential protective effects of light and moderate drinking on cardiovascular diseases and type 2 diabetes do not outweigh the cancer risk associated with these levels of alcohol consumption. As Dr Jürgen Rehm, a member of the WHO Regional Director for Europe's Advisory Council for Noncommunicable Diseases, clarifies, the protective effects of alcohol consumption suggested by some studies may be influenced by the comparison groups chosen and the statistical methods used.

Drinking less or not drinking at all lowers health risks
While there is no guaranteed safe amount of alcohol for anyone, drinking less or not drinking at all lowers health risks. Alcohol is a toxic, psychoactive, and dependence-producing substance. It has been classified as a Group 1 carcinogen, the highest-risk group, which also includes asbestos, radiation, and tobacco. Even low levels of alcohol consumption have been associated with greater risks for hypertension, arrythmias, and cancers of the mouth, throat, and female breast.
The World Health Organization (WHO) has stated that there is no safe amount of alcohol that does not affect health. Dr Carina Ferreira-Borges of the WHO Regional Office for Europe explains that the risk to the drinker's health starts from the first drop of any alcoholic beverage. The less you drink, the safer it is. Vulnerable and disadvantaged populations have higher rates of alcohol-related deaths and hospitalizations, and the harms from a given amount and pattern of drinking are higher for poorer drinkers.
The U.S. Dietary Guidelines recommend that healthy adults who choose to drink can minimize alcohol-related risks by limiting intake to one drink or less for women and two drinks or less for men per day. However, it is important to note that even drinking within these limits does not provide a significant reduction in all-cause mortality. Additionally, past research may have overestimated the benefits of moderate drinking, while current research points to added risks, such as breast cancer, even with low levels of drinking.
For certain individuals, abstaining from alcohol is especially important. This includes people who are pregnant or planning to become pregnant, those under the age of 21, individuals with certain medical conditions or taking medications that interact with alcohol, and those with a history of alcohol use disorder. By not drinking at all, these individuals can significantly reduce their health risks associated with alcohol consumption.
Overall, while moderate drinking may reduce the risk of negative health effects compared to excessive drinking, the current research indicates that the less alcohol consumed, the better. Lowering alcohol intake or abstaining from it altogether can effectively reduce health risks and is recommended for individuals looking to improve their overall health and well-being.

Drinking guidelines for transgender, non-binary, gender diverse, and intersex people
While there is no guaranteed safe amount of alcohol for anyone, general guidelines can help people minimize the risks associated with drinking. The U.S. Dietary Guidelines recommend limiting alcohol intake to one drink or less for women and two drinks or less for men on any single day, not as an average. However, it is important to note that these guidelines are based on binary sex assigned at birth and not on gender identity.
Currently, there are no established drinking guidelines specific to transgender, non-binary, gender diverse, and intersex individuals. This is due to a lack of research and understanding of how alcohol affects these communities. The existing literature suggests that there are differences in how their bodies handle or process alcohol compared to cisgender individuals. As a result, transgender, non-binary, gender diverse, and intersex people should consult their healthcare team about recommended drink limits, as individual circumstances vary.
Some general recommendations for reducing alcohol-related risks include drinking within recommended limits, avoiding heavy and binge drinking patterns, and being aware of the typical weekly volume consumed. Additionally, certain individuals should refrain from drinking altogether, including those who are pregnant or planning to become pregnant, under the legal drinking age, or managing health conditions that can be worsened by alcohol.
It is important to recognize that alcohol use can have negative physiological, psychological, and social consequences. Research has linked even low levels of alcohol consumption to increased risks for hypertension, arrhythmias, and cancers of the mouth, throat, and breast. Therefore, for those who choose to drink, the advice is generally to drink less to minimize risks.
While there are no specific guidelines for transgender, non-binary, gender diverse, and intersex people, ongoing public health attention and research are aimed at improving the understanding of alcohol's effects on these communities. This includes expanding the repertoire of alcohol measures, testing established screening instruments, and considering the complex interplay of physiological sex characteristics and socially constructed gender.

Binge drinking is a spectrum of dependency
While there is no guaranteed safe amount of alcohol for anyone, general guidelines can help minimise the risks. According to the US Dietary Guidelines, men should limit their intake to two drinks or less in a day, while women should have one drink or less in a day. These guidelines are not intended as an average, but rather the amount consumed on any single day.
Binge drinking is a pattern of drinking that brings a person's blood alcohol concentration (BAC) to 0.08% or above. This typically happens when men consume five or more drinks and women consume four or more drinks in about two hours. Binge drinking is a form of alcohol misuse, which includes heavy alcohol use, and is considered high-risk behaviour that should be avoided. Alcohol misuse refers to drinking in a manner, situation, amount, or frequency that could cause harm to oneself or others.
The frequency of heavy drinking days and the weekly volume of alcohol consumption are also factors that influence the risk of developing AUD. Binge drinking can lead to brain damage faster and more severely than chronic drinking. This is due to the substantial amounts of glutamate released and overstimulating the brain as a binge finishes.
Overall, the less alcohol consumed, the better. Those who wish to minimise their risk of alcohol-related harm may choose to abstain or limit their intake according to the guidelines provided by health authorities.

Yes, certain groups should avoid alcohol consumption, including those who are pregnant or planning to become pregnant, under the age of 21, managing health conditions that can be worsened by alcohol, taking medications that interact with alcohol, or recovering from alcohol use disorder.
Alcohol is a toxic, psychoactive, and dependence-producing substance. It is classified as a Group 1 carcinogen, the highest-risk group, and can cause at least seven types of cancer, including bowel and breast cancer. Excessive alcohol consumption increases the risk of early death, injury, and chronic diseases such as liver disease and heart disease.
Excessive alcohol consumption, also known as binge drinking, is defined as drinking upwards of ten drinks in a single week. This pattern of drinking is high risk and should be avoided. It can lead to alcohol use disorder (AUD) and cause social harms such as relationship problems.
