Definitions
Stolle, Sack and Thomasius define binge drinking as episodic excessive drinking.
[Compare: ] There is currently no worldwide consensus on how many drinks constitute a "binge", but in the United States, the term has been described in academic research to mean consuming five or more

, defines binge drinking as "a pattern of drinking that brings a person's blood alcohol concentration (BAC) to 0.08 grams percent or above. This typically happens when men consume five or more drinks, and when women consume four or more drinks, in about two hours." and estimated that about 16% of American adults met these criteria at least four times per month. One 2001 definition from the publication ''Psychology of Addictive Behavior'' states that five drinks for men and four drinks for women must be consumed on one occasion at least once in a two-week period for it to be classed as binge drinking.
This is colloquially known as the "5/4 definition", and depending on the source, the timeframe can vary. In the

, binge drinking is also known as risky single occasion drinking (RSOD)
and can be classified by the drinking of seven or more standard drinks (by males) and five or more standard drinks (by females) within a single day. When BEACH (
Bettering the Evaluation and Care of Health) conducted a study which gathered information of people over the age of 18, it defined binge drinkers as those who consumed six or more standard drinks on one occasion whether that be weekly or monthly.
The above definitions are limited in that they do not take into account the time period over which the drinking occurs or the body mass of the person drinking. A person could be defined as a binge drinker even if he or she never becomes intoxicated. The term, however, has succeeded in drawing public awareness to the problem of excess drinking..

(NIAAA) defines the term "binge drinking" as a pattern of drinking that brings a person's blood alcohol concentration (BAC) to 0.08 percent or above.
Whatever the numerical definition used, heavy drinking or rapid consumption over a short period of time with the intention of becoming intoxicated is often implied when the term is used colloquially, since four or five drinks consumed over the course of a whole day and as an accompaniment to meals will not have the same effects as the same amount consumed over a couple of hours on an empty stomach.
An alternative colloquial term for binge drinking, "going on a bender", formerly implied a drinking spree of several days.

Semi-structured interview were carried out with 64 14- to 17-year-olds who had an experience of binge drinking. These interviews found that motivations included social facilitation which was ease in social situations, individual benefits such as getting a 'buzz' and influences of peer pressure and social norms.
Risk factors for binge drinking among adolescents include: low socioeconomic status, large amount of disposable (pocket) money, sensation and novelty seeking, low self-control, delinquency and having delinquent friends. Other risk factors include: using alcohol as a coping strategy for emotional problems (more common in adolescent girls), excessive drinking among peers, poor relationship with parents, alcohol abuse by parents. Genetic conditions combined with a background of negative environmental factors increase the harmful use of alcohol.
Additionally the risk-taking behavior associated with adolescence promotes binge drinking.

Binge drinking is also associated with an increased risk of unplanned and unprotected sex, unplanned pregnancies, and an increased risk of HIV infection. 10% of women and 19% of men have reported being assaulted as a result of alcohol. Males who drink more than 35 units of alcohol per week report being physically hurt as a result of alcohol, and 15% report physically hurting others as a result of their drinking. Almost 16% of binge drinkers report being taken advantage of sexually, and 8% report taking advantage of another person sexually as a result of alcohol within a one-year period. Heavy drinkers cause approximately 183,000 rapes and sexual assaults, 197,000 robberies, 661,000 aggravated assaults, and 1.7 million simple assaults each year. Binge drinking has been associated with higher probability of divorce, spousal abuse, and poor job performance. Binge drinking can cause adverse effects on the body including effects on blood

Alcohol affects brain development quite significantly especially during adolescence when the brain is still developing. The main lobes that are involved in decision making and complex thought processes are undergoing their final development phase during adolescence and binge drinking can negatively stunt the growth of these frontal lobes.
Adolescence and young adulthood
The high levels of binge drinking among young people and the adverse consequences that include increased risk of alcoholism as an adult and liver disease make binge drinking a major public health issue.

This is particularly interesting, as drinking for the sole purpose of getting drunk remains a major health and social problem on college campuses across the United States. Heavy and regular binge drinking during adolescence is associated with an increased risk of alcoholism. Approximately 40% of alcoholics report heavy drinking during adolescence.
Repeated episodes of excessive drinking, especially at an early age, are thought to cause a profound increase in the risk of developing an alcohol-related disorder (ICD-10, harmful use/dependence syndrome). Heavy drinking is also closely associated with
depression. Those with severe depression have higher rates of alcohol abuse than those with low depression. College students who are depressed are more susceptible to use alcohol than college students who are not depressed. In a study conducted at Harvard University, it was found that about 32% of students surveyed were diagnosable for alcohol abuse and about 6% were diagnosed as alcohol dependent. Binge drinking is also becoming an increasing problem in Australian adolescents, the Australian School Students Alcohol and Drug survey conducted by the National Cancer Council discovered that around 33% of students between years 7 and 11 consumed alcohol in the week leading up to the survey, they also found that 10% of the students participated in binge drinking at a consumption level which is considered dangerous to adults. When the survey results were separated into age groups the findings were that 13% of 15-year-old's and 22% of 17-year-old's had alcohol consumption levels above the daily maximum suggested to adults and that 20% of 17-year-old's had a consumption level of alcohol considered risky to adults.

include social and genetic factors. Several researchers have found that starting drinking before the age of 15 is associated with a fourfold increased risk for developing alcoholism compared to people that delay drinking until age 20 or later. It has been estimated by some that if the age at which people started drinking could be delayed to age 20, there would be a 50% reduction in the number of cases of alcohol use disorder.
However, it is unclear whether this is a causal relationship, or a function of confounding familial (and other) factors associated with both age at first drink and propensity for alcoholism.
The main cause of death among adolescents as a result of binge drinking is road traffic accidents; a third of all fatal road traffic accidents among 15- to 20-year-olds are associated with drinking alcohol. Cyclists and pedestrians are likely to have less spatial awareness and concentration while travelling after binge drinking and, also, it is more common that adolescents that binge-drink drive drunk or are the passenger of a drunk driver. It has been found that 50% of all head injuries in adolescents in the US are associated with alcohol consumption. Violence and suicide combine to become the third-most-common cause of death associated with binge drinking among adolescents. The suicide risk in adolescents is more than four times higher among binge drinkers than non-binge drinking adolescents.
Earlier sexual activity, increased changing of sexual partners, higher rate of unwanted pregnancy, higher rate of sexually transmitted diseases, infertility, and alcohol-related damage to the fetus during pregnancy is associated with binge drinking. Female binge drinkers are three times more likely to be sexually assaulted; 50% of adolescent girls reporting sexual assault were under the influence of alcohol or another psychotropic substance at the time.

effects of alcohol abuse during adolescence can be permanent.
Research in humans, which utilised sophisticated brain scanning technology suggests that in adolescent teenagers, drinking more than four or five drinks once or twice a month results in subtle damage to the teenagers developing brain tissue, in particular the white matter.
However, this research is primarily cross-sectional and done with fairly small sample sizes, making causality less certain.
Several studies have been conducted to discover if there is a link between binge drinking in adolescent years and becoming a chronic alcohol consumer when they transition into adulthood. A particular study conducted by the National Longitudinal Survey of Youth found that harmful drinking during adolescent years was significantly associated with the continuance of dangerous levels of alcohol consumption into adulthood years. Binge drinking is a way for young adolescents to rely alcohol as a way to cope with certain stress or depression.
Central nervous system
Heavy binge drinkers tend to have delayed auditory and verbal memory and deficits in executive planning function and episodic memory, which are similar to deficits seen in
Korsakoff's syndrome. Impairments in spatial working memory and pattern recognition tasks also have been found in heavy binge drinkers. Impulse control is also impaired in binge drinkers, especially female binge drinkers. Additionally, immediate and delayed recall of verbal and visual information is impaired; conversely, semantic organizational ability is better in binge drinkers compared to non-binge drinkers. Studies in adolescents have shown that regular binge drinking may cause long-lasting cognitive impairments, though the threshold needed to produce significant effects remains unclear. Cognitive impairment in adults is also unclear, as one study found no association between binge drinking and cognitive impairment.

with resultant distortion of neurotransmission. Adolescents, females and young adults are most sensitive to the neuropsychological effects of binge drinking. Adolescence, in particular early adolescence, is a developmental stage that is particularly vulnerable to the neurotoxic and neurocognitive adverse effects of binge drinking due to it being a time of significant brain development.

While several rat studies indicate that alcohol is more toxic during adolescence than adulthood, some researchers believe that it remains unclear whether this is also the case in humans. Though heavy binge drinking adolescent humans show impaired brain activity during memory tests and underdeveloped brain structures compared to adolescents who did not binge-drink, they argue that these findings are similar to adult alcoholics who did not abuse alcohol during adolescence.

concluded that alcohol's long-term damage to cognitive processes was the same regardless of whether heavy drinking commenced during adolescence or later.
Pregnancy
Binge drinking is a more important factor rather than average alcohol intake, with regard to the severity of alcohol induced damage to the fetus. Alcohol has definite long-term adverse effects on the fetus, in particular impaired attentional skills and may lead to psychiatric disorders when the child grows up.
In a 2005 study in the US, approximately one in five non-pregnant women binge-drank and one in 25 pregnant women binge-drank.

Binge drinking increases cardiovascular toxicity due to its adverse effects on the electrical conduction system of the heart and the process of
atherothrombosis.
Excessive alcohol consumption is responsible for an average of 80,000 deaths in the U.S. each year
1 and $223.5 billion in economic costs in 2006.
2 More than half of these deaths and three-quarters of the economic costs are due to binge drinking

(poisoning due to reabsorbed waste). The recovery rate is high, with most fatalities due to
septic blood poisoning. A person is more likely to urinate while passed out before the bladder ruptures, as alcohol relaxes the muscles that normally control their bladder.

blackout (alcohol-related amnesia), which can cause shame, guilt, embarrassment, harm to personal relationships, injury or death, and is also associated with the loss of personal belongings.
Cardiovascular system
A recent study conducted on an American College tested to discover if excessive binge drinking would have an effect on the cardiovascular system. From the results they received they found alterations in the binge drinker's macrocirculation and microcirculation functions which may be sign of a risk in cardiovascular disease. The study suggests that binge drinkers with a history of strong binge drinking should be screened regularly.
Pathophysiology
Binge drinking has the propensity to result in brain damage faster as well as more severely than chronic drinking (alcoholism), due to the neurotoxic effects of the repeated rebound withdrawal effects. During the repeated alcohol free stages associated with binge drinking, a larger amount of glutamate is released than occurs during withdrawal from chronic alcohol abuse; additionally this extreme release of glutamate happens on a repeated basis in binge drinkers leading to
excitotoxicity
In excitotoxicity, nerve cells suffer damage or death when the levels of otherwise necessary and safe neurotransmitters such as glutamate become pathologically high, resulting in excessive stimulation of receptors. For example, when glutamate ...

with resultant learning deficits. While brain damage from binge drinking is known to occur as a result of binge drinking patterns, it is unclear how long drinking sessions last and how regular binge drinking is done to cause brain damage in humans. One study found that humans who drank at least 100 drinks (male) or 80 drinks (female) per month (concentrated to 21 occasions or less per month) throughout a three-year period had impaired decision-making skills compared to non-binge drinkers. Repeated acute withdrawal from alcohol, which occurs in heavy binge drinkers, has been shown in several studies to be associated with cognitive deficits as a result of neural

and
synaptic systems mature. This critical developmental stage is where lifelong adult traits e.g., talents, reasoning and complex skills mature; however alcohol and in particular binge drinking may disrupt and interfere with this developmental process. Adolescence is also a period of development characterised by a high level of novel seeking, thrill seeking and risk taking behaviour and thus alcohol and other drug experimentation and abuse is common.
An adolescent rat study found that a short exposure to high levels of alcohol resulted in long-lasting changes to functional brain activity with corresponding abnormalities in

brain waves that persisted into adulthood, including persisting disturbances in sleep EEG with a reduction in slow wave sleep. These EEG findings are similar to premature aging. According to one review of the literature, if the developmental stage of adolescence is similar to the developmental stage of the fetus with regard to sensitivity to the neurotoxic effects of alcohol, and if long-lasting or permanent damage to the brain occurs similar to what animal studies suggest, then this represents a major public health issue due to the high levels of alcohol use by adolescents.
Indeed, alcohol can affect the remodeling and functional changes in synaptic plasticity and neuronal connectivity in different brain regions that occurs during adolescence (''see
this related article'').
Diagnosis
An alcohol use disorder may develop when a person continues to drink heavily despite recurrent social, interpersonal, and/or legal problems. Behaviorally, frequent binge drinking is usually involved, but not everyone who engages in binge drinking develops an alcohol use disorder.
For the purpose of identifying an alcohol use disorder when assessing binge drinking, using a time frame of the past 6 months eliminates false negatives. For example, it has been found that using a narrow two week window for assessment of binge drinking habits leads to 30% of heavy regular binge drinkers wrongly being classed as not having an alcohol use disorder.

is somewhat enhanced when longer timeframes are used.
Prevention
Binge drinking is considered harmful, regardless of a person's age, and there have been calls for healthcare professionals to give increased attention to their patients' drinking habits, especially binge drinking.
Some researchers believe that raising the legal drinking age and screening brief interventions by healthcare providers are the most effective means of reducing morbidity and mortality rates associated with binge drinking.
Programs in the United States have thought of numerous ways to help prevent binge drinking. The Centers for Disease Control and Prevention suggests increasing the cost of alcohol or the excise taxes, restricting the number of stores who may obtain a license to sell liquor (reducing "outlet density"), and implementing stricter law enforcement of underage drinking laws.
There are also a number of individual counseling approaches, such as motivational interviewing and cognitive behavioral approaches, that have been shown to reduce drinking among heavy drinking college students. In 2006, the Wisconsin Initiative to Promote Healthy Lifestyles implemented a program that helps primary care physicians identify and address binge drinking problems in patients. In August 2008, a group of

to 18 (presumably) was one way to curb the "culture of dangerous binge drinking" among college students. This idea is currently the subject of controversy. Proponents argue that the 21 law forces drinking underground and makes it more dangerous than it has to be, while opponents have claimed that lowering the age would only make the situation worse. Despite health warnings, most Australian women drink at least one night a week. But experts are warning they are not only damaging their bodies but are also at risk of attracting sexual predators.
Reduction
Research shows ways to reduce binge drinking or engage in dangerous drinking. Some computer-based intervention appear to reduce binge drinking, an example of which is "rethinking drinking". A systematic review of published research also indicated that face-to-face interventions are most effective in reducing binge drinking among college students, although internet-based interventions may also be beneficial.
Understanding consumer personality and how people view others is important. People were shown ads talking of the harmful effects of binge drinking. People who valued close friends as a sense of who they are, were less likely to want to binge drink after seeing an ad featuring them and a close friend. People who were loners or who did not see close friends important to their sense of who they were reacted better to ads featuring an individual. A similar pattern was shown for ads showing a person driving at dangerous speeds. This suggests ads showing potential harm to citizens from binge drinking or dangerous driving are less effective than ads highlighting a person's close friends.
In 2009 the Australian Government Department of Health and Ageing spent $53.5 million Australian Dollars on National Binge Drinking Strategy to target young Australians. This campaign titled "Don't Turn a Night Out Into a Nightmare" was delivered to the public over many mass media platforms to show the harms and consequences of risky single occasion drinking (RSOD) as binge drinking is defined in Australia. Evidence as to the effectiveness of these types of campaigns is mixed. Research needs to be completed to ensure that the effectiveness of the messages are resulting in a positive shift in the behaviours of the target audience.
Treatment
Due to the risks especially in adolescents, of cognitive impairments and possible irreversible brain damage associated with binge drinking, urgent action has been recommended.
There is some evidence that interventions by employers such as, health and lifestyle checks, psychosocial skills training and peer referral, can reduce the level of binge drinking.
In the US brief motivational interventions have shown some benefit in reducing future binge drinking.
Adolescents who misuse alcohol can benefit from interventions aimed at risk reduction. For more severe cases an intervention involving parents, guardians, or a psychotherapist is recommended.
An effective strategy of intervention for adolescents whose binge drinking leads to admission to hospital, e.g. for alcohol poisoning or injury, is manualised brief interventions at the hospital in one to four counseling sessions each lasting 30 to 60 minutes conducted by trained staff. Evaluation of personal pattern of drinking and associated risks and an emphasis on personal responsibility in a non-condescending manner is recommended during the intervention; discussing and informing and educating the adolescent of possible negative short and
long-term consequences of drinking is recommended. The setting of goals and rules to achieve those goals is also recommended during intervention with problem binge drinking adolescents.
Motivational enhancement therapy also shows promise as a treatment.
Increasing public information and awareness regarding the risks of binge drinking, conducting interviews in emergency departments of young people suspected of harmful drinking patterns and trying to persuade them to accept individual counseling in youth addiction counseling services are effective strategies for reducing the harm of binge drinking. Encouraging recreational and adventurous training activities such as climbing or driving can be used alternative "natural buzzes" to alcohol misuse. Additionally, the provision of educational content about the risks of binge drinking and a risk assessment are beneficial during intervention with young binge drinkers and a referral in the case of an alcohol use disorder for specialised help.
According to the NIAAA definition of "heavy drinkers", men may be at risk for alcohol-related problems if their alcohol consumption exceeds 14

A standard drink is a measure of alcohol consumption representing a hypothetical beverage which contains a fixed amount of pure alcohol. A standard drink varies in volume depending on the alcohol concentration of the beverage (for example, a st ...
s per week or four drinks per day, and women may be at risk if they have more than seven standard drinks per week or three drinks per day. Despite this risk, a 2014 report in the National Survey on Drug Use and Health found that only 10% of either "heavy drinkers" or "binge drinkers" also met the criteria for
alcohol dependence, while only 1.3% of non-binge drinkers met this criteria.
An inference drawn in this study is that evidence-based policy strategies and clinical preventive services may effectively reduce binge drinking without requiring addiction treatment in most cases.
Epidemiology
Binge drinking is more common in men than it is in women. Among students in the US, approximately 50% of men and 39% of women binge drink. Racial differences exist among binge drinking with Hispanics followed by Caucasians having the highest level of binge drinking. Caucasians have been found to be nearly twice as likely to binge drink than blacks. It is a common pattern among
Native Americans.
Among the Australian youth population, 31% of males and 14% of women aged 15–17 years engage in risky alcohol consumption.
Individuals of African descent have a lower level of binge drinking followed by those of Asian descent. In the case of Asians their low level of binge drinking may be due to the presence of the aldehyde dehydrogenase gene (ALDH2, Chromosome 12) in many (but by no means the vast majority) that results in poor metabolism of alcohol, which leads to severe adverse effects such as facial flushing.
Men are more likely to binge drink (up to 81% of alcohol binges are done by men) than women and men are also more likely to develop alcohol dependence than women. People who are homozygous for the ALDH2 gene are less likely to binge-drink due to severe adverse effects that occur even with moderate amounts of alcohol consumption.
College students have been found to be more likely to binge drink than their same age peers who were not enrolled in college. In the US, this effect has caused serious problems with the country's

. This effect is more prevalent in women than in men.
Other factors that have been found to correlate with higher levels of binge drinking include low religiosity, marijuana use, living with roommates, and cigarette use.
History
Society and culture
Binge drinking costs the UK economy approximately £20 billion a year; 17 million working days are estimated to be lost due to hangovers and drink-related illness each year. The cost of binge drinking to employers is estimated to be £6.4 billion and the cost per year of alcohol harm is estimated to cost the National Health Service £2.7 billion.
Urgent action has been recommended to understand the binge drinking culture and its aetiology and pathogenesis and urgent action has been called for to educate people with regard to the dangers of binge drinking.

released a study in October 2011 that showed that in the United States binge drinking costs society $223 billion a year, which amounts to $2 per drink. These costs include health care costs for alcohol-related issues, including liver cirrhosis, loss of work productivity, property damage due to drunk driving, and expenditures related to criminal acts. Overall, 11.9% of binge drinkers drove during or within two hours of their most recent binge drinking episode. Those drinking in licensed establishments (bars, clubs, and restaurants) accounted for 54.3% of these driving episodes. Significant independent risk factors for driving after binge drinking included male gender (AOR=1.75); being aged 35–54 or ≥55 years compared to 18–34 years (AOR=1.58 and 2.37, respectively); and drinking in bars or clubs compared to drinking in the respondent's home (AOR=7.81). Drivers who drank most of their alcohol in licensed establishments consumed an average of 8.1 drinks, and 25.7% of them consumed ≥10 drinks.

. This difference in effect occurs even when a woman's body weight and consumption of alcohol are the same as that of a man. Because of these discrepancies, college-age women tend to experience the consequences of binge drinking before their male counterparts.
There is no known safe level of alcohol consumption either when trying to get pregnant or during pregnancy. With
alcohol abuse remaining highly stigmatized—particularly in the case of pregnant women—some advocate for
treatment programs to focus on a non-judgmental stance, on personal empowerment, and on offering contraceptives to women engaging in sex, in order to prevent
