How much do you really drink compared to everyone else?

No more than 14 units a week, for men and women alike, under the UK Chief Medical Officers’ Low Risk Drinking Guidelines as updated in 2016. Spread them over three or more days rather than saving them up. Fourteen units is roughly 6 pints of average-strength beer, or 10 small 125ml glasses of lower-strength wine. Read it as a low-risk threshold rather than a target, since the guidelines state there is no completely safe level.

14 grams, or 0.6 fluid ounces, of pure alcohol. That works out at roughly 12 ounces of regular 5% beer, 5 ounces of 12% table wine, or 1.5 ounces of 40% spirits. Plenty of real servings hold more than one, including a generous restaurant wine pour and a 16oz pint of 7% IPA, which comes to about 1.9 standard drinks. Counting glasses and counting drinks are not the same exercise.

Yes. The International Agency for Research on Cancer (IARC) classifies alcoholic beverages as a Group 1 carcinogen, meaning carcinogenic to humans. Regular drinking raises the risk of cancers of the mouth, pharynx, larynx, oesophagus, liver, colorectum and female breast. Risk rises with the amount consumed, and no threshold has been identified below which the extra risk disappears. Alcohol accounts for roughly 4% of UK cancer cases a year.

It depends which country you ask. The UK CMO figure of 14 units a week for both sexes is roughly 112 grams of pure alcohol. NIAAA in the US calls it moderate up to 14 standard drinks a week for men and 7 for women, which puts the American male limit well above the British one. WHO disputes the word itself, since even moderate consumption carries cancer risk and “moderate” implies a safety the population-scale evidence does not support.

A 10-question screen built by the World Health Organization in 1989 to pick out drinking that is hazardous or harmful, and dependence with it. Scores run from 0 to 40, with 8 or above the standard cutoff for hazardous drinking and 20 or above pointing to possible dependence. AUDIT-C is the three-question short form used in primary care, covering frequency, typical quantity and binge frequency. In the six-country WHO study that built it, 92% of people with hazardous or harmful drinking scored 8 or more, and 94% of those without scored under 8.

US total alcohol per capita consumption runs at about 9.6 litres of pure alcohol a year for people aged 15 and over, on the WHO's estimate for 2023. That sits above the global average and below the heaviest-drinking Europeans, with Moldova, Lithuania and the Czech Republic near the top. The American figure is close to Australia and the UK, and far above the Middle East, South and Southeast Asia and sub-Saharan Africa, where large abstaining populations pull the regional averages down.

The J-curve held that moderate drinkers had lower cardiovascular mortality than abstainers and heavy drinkers alike, which is what observational studies in the 1990s and 2000s kept showing. Mendelian randomisation, which uses genetic variants linked to lower drinking as a natural experiment, has since cast doubt on it. Among current drinkers in 83 prospective studies, Wood et al. (2018, Lancet, 599,912 participants) found the lowest all-cause mortality at about 100 grams of alcohol a week, roughly 12.5 UK units, with more drinking raising the risk of stroke, heart failure and fatal hypertensive disease even as heart attack risk edged down. Canada's 2023 guidance rejected the framing outright, and alcohol's effect on blood pressure is one of the most direct routes by which moderate drinking still raises cardiovascular risk.

Alcohol use disorder is the DSM-5 diagnosis for drinking marked by loss of control, preoccupation, continued use despite the harm it causes, tolerance, or withdrawal on cutting back, and it is graded mild, moderate or severe. NIAAA estimated 28.9 million Americans aged 12 and older had AUD in 2023, about 10.2% of that population. Fewer than 10% of them get treatment in a given year, one of the widest treatment gaps in mental health.

About 21.7% of Americans aged 12 and over, 61.4 million people, reported binge drinking in the past month on SAMHSA's 2023 National Survey on Drug Use and Health. Binge means 5 or more standard drinks on one occasion for men, 4 or more for women. Heavy use, meaning binge drinking on 5 or more days in the month, ran at 5.8%. Binge drinking and alcohol use disorder both peak among young adults aged 18 to 25, and Esser et al. (2014) found 90% of US excessive drinkers didn't meet the criteria for alcohol dependence.

Drinking peaks in the late teens and early 20s in most developed countries, then falls through the 30s as work and family crowd it out. A partial rebound shows up in the 40s and 50s, particularly among women whose children have left home. After 65 both prevalence and quantity drop away, on health grounds and medication and fewer occasions to drink at. The useful wrinkle in HSE 2024 is that older drinkers drink on more days of the week while younger ones put more into fewer nights, so a settled older drinker can post a high weekly total while feeling entirely in control. Alcohol is also one of the inputs in the biological age calculator, which tracks the cumulative cellular cost.

A voluntary cut in drinking driven by wellness rather than by recovery, named after journalist Ruby Warrington's 2018 book. You see it in Dry January and Sober October, in alcohol-free social spaces, and in the no/low category, which IWSR Drinks Market Analysis tracks as a growing category across its key global markets. Under-35s in the US keep reporting less drinking than earlier cohorts did at the same age, and NIAAA data has the share of adults reporting no past-month drinking rising modestly but steadily from 2015 to 2023.

Canada's Centre on Substance Use and Addiction rewrote its guidance in January 2023 and stated that no amount of alcohol is safe for health, which drew attention well beyond Canada. It bands 1 to 2 standard drinks a week as "low risk," 3 to 6 as "moderate risk," and 7 or more as "increasingly high risk." The previous Canadian advice allowed up to 10 drinks a week for women and 15 for men, so this was a very large cut, and it is stricter than current UK, US and WHO guidance. Cancer risk at low doses did most of the work, alongside the disputed J-curve and fresh meta-analyses of all-cause mortality.

More than 14 standard drinks a week, or more than 4 on any single day, for men. For women the lines are more than 7 a week or more than 3 in a day. That difference reflects body water percentage, lower levels of alcohol dehydrogenase in women, and pharmacokinetics that leave women at higher blood alcohol concentrations than men from the same intake. NIAAA treats the 4-a-day and 14-a-week figures for men as a low-risk limit rather than a recommendation, and drinking past them raises the risk of AUD and of alcohol-attributable injury.
